110 Dr. J. E. Gray on the Tortoises 



1. Einys t'ncisa, Dumdril and Bocourt, I.e. p. 11, t. i. & il. 



From the mountains of Conchavona, in the province of La 

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

 habitants saj it is never found in Avater. 



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

 figured that it is impossible to determine what modern genus 

 or species it may belong to. 



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

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



Cholcepus 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. 

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

 magazine of incongruous species called Emys by these authors. 



3. EniTjs venusta, Gray, Cat. Sh. Kept. 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 dififerent from, 

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

 p. 286 ; Gray, Cat. Sh. Kept. 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 Callichelys con- 

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

 Hand-list Sh. Kept. 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. Kept, 

 p. 36). 



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

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

 belonging to C. callirostris.
