perfect and without tails. Several more specimens 

 came to light later. Mr. Mole fed the adults on 

 "frogs," presumably Leptodactylus sp., as there are 

 no Bana in South America. A large specimen, about 

 six inches head and body, will take four "frogs" at 

 a meal, sometimes from one's hand. Mr. Mole has 

 tried to feed them small fish, — as we have also done 

 with specimens from British Guiana, at Bronx Park, 

 — but they take nothing but frogs.

NOTES ON COLPOCHELYS KEMPI 

 GARMAN. 



In examining a few of the turtles in the collec- 

 tion of the American Museum of Natural History, 

 the writers recently found two specimens of the sea 

 turtle Colpochelys kempi Garman, which appear 

 worthy of note. This species ranges from the Gulf 

 of- Mexico along the Atlantic coast of the United 

 States as far north as New Jersey. One of the pres- 

 ent specimens is from Cape Hatteras, and the second 

 bears no closer locality than "United States" (col- 

 lected by Prince Maximilian von Wied). Both were 

 labeled Thalassochelys caretta (L.). 



The two specimens agree in the possession of the 

 chief external characteristics which differentiate C. 

 kempi from Caretta caretta. There are four infra- 

 marginals, of which the anterior is the largest; the 

 inferior face of the marginals is proportionately much 

 broader; and the parietals are much longer. Both 

 have the prominent alveolar ridge of the upper jaw 

 with the deep median notch, and the anterior median 

 tooth of the lower jaw. 



The larger specimen, A. M. N. H. No. 2205, 

 from Cape Hatteras, presents a striking peculiarity 

 of the carapace in having an interrupted keel, rising 

 at the posterior edges of the first three neurals into 

 prominent upturned spines, that of the second neural
