 Terrapene reticulata, Bonap. Ohs. Cuv. R. A. 155 (1830). 



Hab. North America, on the coast between North Caro- 

 lina and Georgia. The flesh is much esteemed. 



The shell is about 9 or 1 inches long. 



22. Emys Mobilensis. The Mobile Terrapen. 



"Shell oval, ecarinate, convex anteriorly, depressed pos- 

 teriorly, entire in front, emarginate and subserrate behind ; 

 jaws serrated, inferior furnished with a hook." Length 

 15 inches. 

 Emys Mobilensis, Holbrook, N. A. Herpet. ed. 2. i. 71 . t. 9. 



Hab. North America (Alabama). Greatly esteemed at 

 Mobile as an article of food. 



The figures greatly resemble my E. ventricosa, but the 

 margin is represented as having sutural spots, which is not 

 the case with that animal. See No. 25. 



23. Emys Troostii. Dr. Troost's Terrapen. 

 " Shell subrotund, much depressed, ecarinate ; posterior 

 part of the margin very slightly serrated ; lateral and mar- 

 ginal plates marked with blotches or lines of horn-colour. 

 Sternum broad, dirty yellow, each plate with a large blotch 

 near its centre. Head long, narrow ; upper jaw emargi- 

 nate, lower jaw furnished with a tooth." 



Emys Troostii, Holbrook, N. A. Herpet. i. 123. t. 20. 

 Hab. N. America (Cumberland River). 



Length of shell 8 inches. 



I have received an indistinctly marked specimen (evi- 

 dently from its having lived in a muddy river) of E. 

 scripta, from the Leydeu Museum, under the above name, 

 and it is said to come from the Cumberland River ! The 

 mark on the shell was only to be seen when the homy 

 plates were removed. 



Can this be the shell intended in the above description ? 



24. Emys labyrinthica. The Netted Terrapen. 

 Shell oval, regular ; hinder edge rather sinuous and ele- 

 vated ; central hue swollen, not keeled, rugose, green, more 



or less brown, with a great number of sinuous and twisted 

 yellow lines. Sternum entire in front, nicked behind, yel- 

 low. Head rather large ; head and neck yellow streaked ; 

 lower jaw toothed. 



Emys labyrinthica, " Lesueur, MSS.," Bum. Cat. Rept. 

 Mus.H.N. 13 (1851). 



Hab. North America (Wabash River). 



What is Emys elegans, Wied, Voy.Amer.Septent.m. 255, 

 from North America ? 



** Borsal shields variegated or ringed; the marginal 

 shield with a single spot or ring, with the centre on 

 its hinder margin. The costal shields with a single 

 pale ring, surrounding the dark areola, giving out 

 pale streaks from its circumference, diverging {some- 

 times anastomosing or crossing each other) towards 

 the margin of the plates. 



§ The areola and ring on the hinder upper angle of the 

 first or front, and the front (?) upper angle of the 

 other costal plates ; vertebral plates ? 



25. Emys ventricosa. The Swollen Terrapen. 

 Tab. XIV. 



Animal 



■ ? Shell convex, ventricose, swollen on the 



sides of the back, slightly keeled in front, and more sharply 

 so behind ; margin toothed behind ; the hinder lateral mar- 

 gin bent up over the legs. Back rugose, blackish-brown, 

 with some indistinct dark-edged yellow lines diverging from 

 a squarish ring in the upper angle of the costal shields ; 

 upper side of the marginal plates with some dark rings 

 concentrically round the hinder outer margin. The first 

 vertebra urceolate, about as broad as long ; the second, 

 third and fourth elongate, six-sided. Sternum convex, pale 

 yellow, with a narrow dark edge to the plates.

? 



a. Adult (shell only). 



The sternum may in the perfect specimen be more 

 distinctly marked, as this example had evidently died in 

 confinement, as proved by the carious state of the centre 

 of the sternum. The colour is veiy much suffused in the 

 hinder part, almost hiding the pattern of the paler marks, 

 and the central dorsal shields are rubbed and worn, hiding 

 the pattern in that part of the shell. The swollen form.
