KINOSTERNON. 35 



j3. Scutellis marginalibus lateralibus sub-latioribus, (v. t. 

 Mus. Bell.) 



Hab. in America Meridionali; Mexico, lJ^eigman?i; Brasilia, 

 SpLv. (v. t. Mus. Brit. Bell, &c.) 



The finest species of the genus. Shaw's figure is very 



good, but the anterior marginal plates which exist in his 



specimen have been omitted by the artist. Tt varies in regard 



to the breadth of the dorsal plates and the distance between 



the dorsal keels. Weigmann, (Isis, xxi. 364,) refers to 



Shaw's figure, and his description agrees excellently with our 



species, except that he says sterno antice mohili angustissimo, 



and areolJs steriii 12, neither of which correspond. The 



usually accurate Schweiger falls into the same error with 



regard to the sternal plates, in his description of both the old 



and young state, but this may originate in the gular plates 



being crossed by an elevated ridge in the usual place of the 



suture. All the specimens I have seen have only had eleven. 



Kinosternon hrevicaudatum, Spix, t. 13, appears only to 



differ in the tail and hinder lobe being rather shorter, perhaps 



a male ; both the species have 23 marginal plates in the 



figures, and 25 according to the text.
