A review of the literature given in the above list, only those works marked (*) 

 having been inaccessible to me. has brought out the following facts, which are 



presented in full: 



1792. Schoepff, J. D. — Historia Testudinum, pp. 64-66, pi. xv. 



This author describes "the terrapin" underthe name Testudo terrapin, and gives three figures of 

 the animal, Bhbwing the carapace, plastron, and a front view (the first two figures colored). The 

 habitat is given as North America. ' 



The figure shows a shell which must have come from tin- northern form, probably from Delaware 

 Bay or northward. The carapace is brown with darker mottlings, and the concentric ridges ou the 

 plates an- plainly visible. The greatest height is at the 3d vertebral plate. The plastron is light yel- 

 low with a large orange blotch ami an irregular dusky ring or rectangle on each plate. 



Unfortunately Schoepff seems t" have Keen misled bythe name terrapin, and accordingly regarded 

 his species as identical with the species of t (melin, which was based on the specie- described by brown 

 from Jamaica (Rept. Jamaica | under tin- name Testudo terrapin or Testudo palustris. The hitter animal 

 has nothing to do with the one in question aid belongs to a distinct genus, Pseudemys. 



1793. Schoepff, .1. 1». — Naturgeschichte der Schildkroten, Abth. 3 u. 4, s. 71-74. 



The description previously cited is given, though in German instead of Latin, with the additional 

 statement that two of the shells upon which the species was based were brought by the author from 

 North America. From the context we may infer that these two shells came from Long Island. The 

 figure shown is the same as in the edition already referred to. 



1800. Bechstein, .1. M. — Lacepede's Naturgeschichte der Amphibien, I, pp. 166-170, pi. iv, fig. 2. 



Under the name Testudo terrapin the description of Schoepff is repeated. The plate is a reduced 

 copy of Schoepff's figure, showing the shell from the side.

berg '/'< rrapins ibidem nuncupari solent, et hoc sub nomine in soris Philadelphia?, et alibi, venules prostant. Licet capitis

In reeentissime epistola. Rev. Miihlenbeig sequentia addit: "Habitat in aquis salsis; ad pedis magnitudinem inter- 

 dum oxereseit. Pedes palmati; palmse5, plantse 1-dactyla . Cauda brevis."
