ZOOLOGY. ! 
Two-HEADED SNAKES.—In reference to the two-headed snakes 
e 
present year, I would say that there exists another specimen 
without locality in the collection of the Lyceum of Natural His- 
tory of Williams College. In the same collection is a specimen 
of a five-legged frog (Rana sp.) from Rochester, N. Y. In this 
the fifth leg is situated between the two posterior pairs and just 
above the anus, and is in all respects as perfect as the two nor- 
mal ones. The specimen is about as large as the average X. 
palustris, and, if I remember rightly, belongs to that species. 
In “An Essay on the Natural History of Guiana,” London, 
T. Becket and P. A. DeHondt, 1769, the author discourses upon 
the Amphisbene of that country, stating that they have a head at 
each extremity, and “yet, except these there is no animal in 
nature that is thought to have two heads ;” and in a foot note on 
the same page (214) says: “I have received a particular descrip- 
tion of a monstrous Azmphisbena found near Lake Champlain in 
North America by an officer in the American service, who, with 
one of his Majesty’s draughtsmen, was sent during the late war 
to make a survey of that lake. They were previously informed 
by the Indians of the existence of these serpents, one of which 
they killed near a bay in Lake Champlain, which in the maps of 
that country has been since called Double-headed-snake bay. 
This serpent was a small one of the kind, it being about fifteen 
inches in length and largest near the middle, terminating in a 
slender tail. The body at the other end divided into two necks 
of equal size, to each of which was joined a perfect head, with 
two eyes, a large mouth and throat, a forked tongue, with teeth 
of the same species with those of the rattlesnake. The color of 
and disposition resembling those of the rattlesnake. This ser- 
ent was a perfect monster, of whose existence I should strongly 
doubt, did I not think the veracity of the gentlemen from whom 
I have this information, and by whom it was unquestionably 
killed, unquestionable.” 
__ The frontispiece of the same volume gives a figure of this same 
specimen, drawn by M. Park, and bearing the inscription “ Am-
