(vith warts ; parotids small, covered with pores ; under parts thickly covered 

 all over with granulations. 



Coloration. Brownish black above, with a yellowish dorsal band extending 

 from the occiput to near the anus ; on either side of this a number of jet black 

 blotches, not always very distinct; head olive colored above or fuscous, a black 

 spot in front of each parotid and upon occiput, in the latter situation sometimes 

 coalescing so as to form an irregular band ; the spots in front of the parotids 

 not always pi'esent ; an olive colored irregular broad band upon the sides, com- 

 mencing at the parotids and extending upon the tbighs ; thighs mottled poste- 

 siorly with yellow ; extremities broadly banded with brown, and narrowly with 

 yellow; under parts ochraceous. In a specimen procured from Prof. Agassiz, 

 and deposited in the Academy by Dr. Holbrook, the ground color of the body 

 above is black, the dorsal and lateral bands fuscous, extremities banded with 

 black, under parts fuscous. 



Dimensions of largest specimen. Length 3 inches (Fr.) from extremity of 

 snout to posterior extremity of body; length of head 1 inch 2 lines; greatest 

 breadth 1 inch 2 lines; length of arm 8 lines; of forearm 9 lines; of palm of 

 hand to extremity of longest finger 8 lines ; of thigh 1 inch 1 line ; of tibia 1 

 inch 1 line; of tarsus 8i lines; of sole to extremity of longest toe 1 inch. 



Ilab. Texas. Seven specimens in Museum of Acad. Nat. Sciences. 



Gen. Remarks. This toad is decidedly South American i*i its type, differing 

 entirely in the configuration of the head from any of the North American species. 



It is remarkable, as we have before observed, that the fresh water turtles in 

 Texas and New Mexico appear to be so rare, and we have as yet received none 

 of the Salamandridse from either of these regions, with the exception of an Am- 

 bystoma, viz., A. nebulosum. 



Besides the above we have recently received from Dr. Hammond, of the U. S. 

 Army, stationed at Fort Riley, Kansas, a further collection of reptiles, viz., Cro- 

 taphytus collaris, two specimens. One of these has a double interrupted black 

 collar, the body above marked with transverse lines of white spots, the inter- 

 spaces minutely white spotted ; chin and tail marked with bluish ; abdomen, 

 under parts of extremities and tail immaculate ; intermaxillary teeth small, fol- 

 lowed by others larger, conical, the posterior teeth tricuspid ; palatine teeth 

 very remarkably developed ; tongue slightly notched in front and free, emargi- 

 nate posteriorly ; eighteen femoral pores on each side. Three specimens of 

 Phrynosoma Douglassii, one of Cnemidophorus gularis, B. and G., one of Ophi- 

 saurus ventralis, (striatulus, Cuv.,) two of Coryphodon constrictor, (young,) one 

 1 foot 10 lines in length, with the usual markings; one of Elaphis confinis ? 

 (Scotophis confinis, B. and G.,) 1 foot 2 inches 8 lines in length ; 25 rows of 

 scales ; abdom. scut. 233 ; sub. caud. 62; 29 black blotches upon body, 8 upon 

 tail, a smaller intermediate lateral row of black spots on eack side ; abdomen 

 black spotted. (We have recently received the same species from Dennisville, 

 Cape May County, New Jersey, presented by our fellow member S. Ashmead. 

 In this specimen, which is smaller, there are from 25 to 27 rows of scales.) One 

 of Ablabes triangulum, (var. calligaster ;) 25 rows of scales; a triangular spot 

 with its base resting on the frontal ; the apex extending one and a half lines 

 behind the posterior margin of the occipitals, and two long blotches commencing 

 about half a line behind the post-oculars, each about three-fourths of an inch 

 in length ; transverse blotches narrow. One fine specimen of Coronella, similar 

 to the one described in the last number of the Proceedings, but much larger, 

 measuring 1 foot 11 J inches in length, and two inches in circumference. (The 

 red blotches in this specimen are for the most part much wider apart, the black 

 rings approaching each other near and upon the tail ; in one spot near the tail 

 the red has almost totally disappeared.) One Coronella Sayi, (young,) var. see 

 Marcy's Report, pi. vii. One Heterodon nasicus. One Bufo punctatus, (young 

 of Americanus.) Three Ambystoma, (var. luridum,) and two Siredons. These
