Hence it would appear, that with the exception of Emys decussata, Crocodilus 

 acutus, Spb.-Briodactylus sputator, Anolis Sagrsi, Leionotus maculatus, Dro- 

 micus aatillensis, and Typhlops lumbricalis, unless several of the others have 

 been incorrectly determined, the species belonging to the Islands Jamaica and 

 Cuba, although but 90 miles distant, are altogether different, and that several 

 of the genera vyhich exist in the one are wanting in the other. Besides the 

 above we have in our collection a small serpent of the size of a Calamarian, 

 with a very short and broad frontal (vertical) plate, a large pre-ocular, no loral 

 and broad gastrostega, carinated scales and a double row of black spots along 

 the back, from Jamaica, included in the donation of Dr. Penrock, which is 

 identical with Storeria DeKayi, B. & G. (Ischognathus DeKayi, Dum. et Bib.* 

 With the exception of Anolis Carolinensis, the reptiles of Cuba differ in their 

 species altogether from those of the United States, even the southern portion of 

 it; and not only so, but with the exception of Emys, Hylodes and Bufo, and 

 perhaps Ischognathus, there does not appear to be even a genus common to the 

 two countries. Were the Herpetology of each of the West India Islands 

 fully known and very accurately determined, many highly interesting and 

 important facts would be developed, tending much to elucidate the laws which 

 govern the geographical distribution of species.

Five specimens of Emys pseudo-grographica, (young.) The shell of the 

 largest of these specimens measures two and a half inches in length, by two 

 inches, five lines in breadth, and is almost orbicular; the carinse upon the ver- 

 tebral plates are very distinct. Color of carapax olive, with orange colored con- 

 centric and irregular lines, most conspicuous when the epidermis is removed ; 

 an areola towards the posterior margin of each of the plates ; sternum yellowish, 

 marked with irregular dark colored lines ; extremities and head and neck marked 

 with longitudinal lines of yellow and black ; a curvilinear transverse yellow band 

 on each side, behind the eyes continuous with one running down the neck, and 

 a longitutinal one between the eyes ; 24 marginal plates. This species, according 

 to Prof. Holbrook, is found in many of the rivers that empty into the Mississippi, 

 but never east of the Alleghanies.

Three specimens of Crotaphytus coUaris, Holb. 



These differ from those from the Creek boundary presented by Dr. Woodhouse, 

 and another large specimen in the collection of the Academy from Arkansas, in 

 wanting the numerous spots with which the latter are covered. The black 

 bands upon the neck and between the shoulders are very distinct ; the general 

 color above is blue, more or less deep, with a tinge of green, with transverse 

 bands of white upon the body and tail; deeper bands of blue upon the posterior 

 extremities; under parts white, with dark colored markings under the chin in 

 two of the young; the plates upon the front in all the specimens are, for the 

 most part larger than those upon the muzzle ; those constituting the semi- circular 

 ridges along the internal margin of the orbit quite large ; occipital plate distinct ; 



*This species has a wide range, being found in Massachusetts and Georgia. 

 Dumeril and Bibron say they have received a specimen from Mexico.
