2. On a New Species or SALAMANDER FROM CALIFORNIA. By J. E. Gray, Pa.D., F.R.S., V.P.Z.S.
(Reptilia, Pl. VII.)
Mr. Henry Gurney most kindly sent to the Zoological Society for exhibition some Reptiles, from Monterey in California, with the de-, sire that the specimens should afterwards be placed in the British Museum. Among the rest was a very fine and large specimen of a Triton, which has much the external appearance of the large white- spotted Ambyostoma Caroline of the eastern part of the United States of America. On more minute examination and comparison, it proved to be quite distinct ; and as I do not find any description of it in any of the American papers on these animals, I have sent a comparative description of the two species.
1. AmByostoma Caro.in#&, Gray, Cat. Amph. B. M. 35.
Brown; small spot over orbit, large spot on each side the occiput, on each leg near the joint, and a series down each side of the back and tail, white; palatine teeth in a short, nearly straight line, be- tween and not reaching to the internal nostrils, and with a separate small group of teeth behind each internal nostril.
2. AMBYOSTOMA CALIFORNIENSE.
Black ; sides of lips, lower part of neck, body and tail, and limbs, with large white spots; palatine teeth in an elongated angular trans- verse line, bent forwards in the middle and extending to the outer edge of the hinder part of the internal nostril.
Hab. California, Monterey, in a well (Gurney).
A smaller white spot on each side of the back, not symmetrical ; the one on the right side being much in front of the other.
Ambyostoma punctulatum, Gray, Cat. Amph. B. M. 37, has the tongue free on the side, and is nearly allied to the genus Plethodon : the palatine teeth are very indistinct, not forming a regular ridge.

3. Description oF a New Species or Tortoise (Testupo PLANICEPS), FROM THE GaLAPAGOs ISLANDS. By J. E. Gray, Pa.D., F.R.S., V.P.Z.S., P.B.S. erc.
After the examination of the specimens of the large Black Tor- toise (Testudo Indica) in the various English and continental col- lections, including the specimens which had served Schweiger, Schle- gel, Fitzinger, Dumeril and Bibron, and others, as the types of spe- cies, I placed them all in the ‘Catalogue of the Tortoises, Croco- diles and Amphisbzenians in the Collection of the British Museum,’ as varieties of a single, very variable species, which had been scat- tered by man in different tropical parts of the globe. I see no cause to change my opinion with respect to the head now about to be de- scribed, even should it prove to be that of a black species, which is possible, as the black species is the only one known which has any affinity to it in point of size. The skull now described was sent to Haslar Hospital, and said to have been taken from a specimen brought from the Galapagos Islands. The Black Tortoise of those islands has been described by Dr. Harlan under the name of Testudo elephan- topus ; but his figure and description so exactly agree with the adult Testudo Indica, and the specimen in the Gardens of the Zoological Society brought from the Galapagos Islands, is so exactly similar to the specimen of Testudo Indica from the Mauritius, that I cannot think that the usual Galapagos Tortoise is different from that spe- cies, or like the skull here noticed. I therefore propose to designate this species by the provisional name of Testudo planiceps. The fol- lowing comparative statement of the characters presented by this skull and that of 7. Indica, will show the differences which exist be- tween them.
Testupo Inpica.
Skull high, convex.
Forehead convex, rounded to the nose-cavity; broad between the eyes.
Temples flat behind.
Cheeks small, four-sided.
Edge of the jaw between the nose- cavity and the mouth narrow and rounded.
Nose-cavity oblong, nearly twice as high as broad, contracted on each side above. :
Palate broad, oblong, very deeply concave, and with concave con- verging sides in front.
TESTUDO PLANICEPS.
Skull much-depressed, flat.
Forehead flat, with a rapid de- clivity towards the nose-cavity ; narrow between the eyes.
Temples produced, bent in be- hind.
Cheeks large, subtrigonal.
Edge of the jaw between the nose- cavity and the mouth high and erect.
Nose-cavity nearly square, scarce- ly higher than broad, and very little contracted above.
Palate narrow, nearly lozenge- shaped, truncated behind, rather deeply concave, with straight converging sides in front.

A portion of a letter from Mr. Louis Fraser, H.M. Consul at Whi- dah, was read, in which the writer mentioned that he had received accounts of the occurrence of a large Ape in the vicinity of Fernando Po. He says it has only been brought down to the colony on two or three occasions. The natives call it Tap-par-po-har, and sup- pose it to be a Chimpanzee ; but from the description they give of it, he thinks it must be a Cynocephalus. The people say it is as large as a man, that it has a long head and a very short tail, and that it barks like a dog. He adds that there are curious tales current about the animal, which he will endeavour to collect.
The following papers were also read :—
1. Descriptions or Two NEw Birps, FROM FERNANDO Po. By Louis Fraser.
Buso Pornsis, Fraser.
Brownish yellow, each feather barred with brown, the brown pre- dominating on the crown, shoulders and middle of the back; tail
14
above barred with brown and greyish brown alternately ; twelve bars of each colour. }
Total length 16 inches; gape, 12; wing, 12; tail, 7; tarsi, 14.
Hab. Fernando Po. po
Killed in June. The specimen from which the above description was taken is the only one that has been seen by the town’s-people ; consequently I presume it is very scarce, at least in this part (Cla- rence) of the island. The natives say it destroys fowls, which here roost in the trees.
Native name ‘Oko.’ This is evidently a generic term, as the same name is applied to my Striw Poensis.
Buceros Poensts, Fraser.
Female by dissection. Head and neck maroon, the feathers of the head standing out in apparent disorder, as in Buceros comatus ; the rest of the plumage black, the back and tail having bronze reflections ; the four outer tail-feathers terminated with white.
Cere czerulean-blue ; upper part of throat-sac French-white, middle a blending of French-white and blue, terminated with czerulean-blue ; these fleshy parts are much wrinkled; legs and feet deep blue.
Total length 30 inches; gape, 6; wing, 143; tail, 13; tarsi, 13.
Hab. Fernando Po.
Killed in the month of July, in deep moult.
Native name, ‘Oon-cot-to.’ The natives say it cries, as it flies, ‘ How-oo-ar, how-oo-ar, how-oo-ar.’. Very shy. Makes its nest in holes of very large trees, in the dry season; lays two eggs. These birds used to be common in the neighbourhood of Clarence, but since the introduction of guns they have been much shot, and have retired to the mountain.
Palm oil nuts, only, were found in the gizzard, which was soft, almost like a stomach ; skin very thin and difficult to prepare. Be- tween the skin and body appeared to be air-cells.
The male is said to differ materially, but I have not been fortu- nate enough to procure a specimen.
