110 Dr. J. E. Gray on the Tortoises 



1. Emys incisa, Dumeril and Bocourt, I.e. p. 11, t. i. & ii. 



From the mountains of Conchavona, in the province of La 

 Union, one of the ports of Salvador on the Pacific. The in- 

 habitants say it is never found in water. 



It appears to be an Emys ; but the head is so indistinctly 

 figured that it is impossible to determine what modern genus 

 or species it may belong to. 



2. Emys areolata, Dum. Arch, du Mus. 1852, tome vi. 

 p. 223, t. xiv. ; Bocourt, I.e. p. 13. 



Choloepus areolatus, Cope, Proc. Acad. Nat. Sci. Philad. 1866, p. 123. 



M. Bocourt observes that fig. 1 in the plate cited repre- 

 sents more plates than the species possesses, the artist being 

 apparently misled by the irregularity in one side of the cara- 

 pace. 



In the ' Supplement to the Catalogue of Shield Reptiles,' 

 p. 42, I observed that this species was probably a variety of 

 Malaclemmys concentrica. The examination of the palate, 

 which would at once settle this question, is not noted in MM. 

 Dumeril and Bocourt's essay, but the species is left in that 

 magazine of incongruous species called Emys by these authors. 



3. Emys venusta, Gray, Cat. Sh. Rept. 1855, p. 24, t. xii. a ; 

 Bocourt, I.e. p. 13. 



He refers to a peculiarity in the genito-urinal organs de- 

 scribed by Vautherin, Ann. Sci. Nat. ser. 5, p. 12. 



4. Emys Grayi, Dum. & Bocourt, I.e. p. 13, t. iii. f. 2, 2 a. 



This species is described as allied to, but different from, 

 Emys ornata, Bell, MSS. ; Dum. & Bibr. Erp. Gen. t. ii. 

 p. 286 ; Gray, Cat. Sh. Rept. p. 24, t. xii. ; Bocourt, I.e. t. iii. 

 f. 1 & 1 a, figured from a specimen presented by Mr. Bell to 

 the French Museum. E. Grayi is found on the east coast of 

 Guatemala, at the mouth of the Nagualate. 



I believe that this species is the same as Gallichelys con- 

 cinna, Gray, Ann. & Mag. Nat. Hist. 1873, x. p. 148 ; 

 Hand-list Sh. Rept. p. 48*. Described from two specimens 

 received from Tehuantepec, San Mateo. 



This species has nothing to do with Emys Grayi of Giinther, 

 P. Z. S. 1869, p. 504, t. 38, from Bussora (Emmenia Grayi, 

 Gray, Suppl. Cat. Sh. Rept. p. 38, and Hand-list Sh. Rept. 

 p. 36). 



* In the ' Hand-list of Shield Keptiles,' p. 48, the name accidentally 

 dropped out in making up the pages, and the specimens are referred to a9 

 belonging to C. cattirostris.
