1. Cistudo Carolina (p. 39). 



M. Leconte erroneously cousitlers the variety C. Blan- 

 dingii of Holbrook as synonymous with Lutretnys Melea- 

 gris, a European species. — Jouni. Acad. Philad. vii. 189. 



M. Leconte, not having seen C. Mexicana, refers it as a 

 variety of C. Carolina with doubt. 



14. KINOSTERNON (p. 43). 



In the Proceedings of the Academy of Natural Sciences 

 of Philadelphia for 1854, vol. iii. no. 5. p. 183, there is a 

 paper by John Leconte, entitled " Descriptions of Four 

 Species of Kinosternon" read on the 31st October 1854. 

 The genus is divided into three groups, thus : — 



I. Consisting of those with bivalve sterna ; the valves 

 joined to the abdominal piece by ligamentous hinges. 



1. K. longicaudatmn, Spix, Bras. 17. t. 12. 



2. K. scorpoides. Surinam. 



3. K. Mexiconum. Testa ovali, valde convexa, fusco-lu- 

 tescente vel nigricante ; dorso fortiter tricarinato, margine 

 undique decHvi, scutis vertebralibus secundo, tertio et quarto 

 elongatis. Sterno utrinque rotundato, integerrimo ; cauda 

 unguiculata. Mexico. 



4. K. integrum. Testa fusca, regulari, ovali, convexa, 

 carinata, declivi, margine postice dispanso, laterali perpen-' 

 diculari. Sterno magno, bivalvi, cistani omnino occludente, 

 antice rotundato, postice paulo emarginato ; cauda brevis- 

 sima, mutica. Mexico. 



5. K. lexicostomum, Dumcril, Mus. Acad. 



II. Anterior valve of sternum joined to the abdominal 

 portion by a ligament and partly by a suture, the posterior 



by suture only ; wings tolerably long, with a deep divided 

 groove on the anterior part. 



6. K. Pennsylvanicum. From Canada to Florida. 



7. K. Sonoriense. Testa modice convexa, postice latiore, 

 antice et postice declivi, margine antice et postice dispanso, 

 medio declivi, dorso indistincte tricarinato, carina intermedia 

 vertebrali evidentiore ; alarum canali leviter exarata, prope 

 rudimentali ; cauda unguiculata. Tacson in Sonora. The 

 shell much less elevated than any other species. 



III. Sternum narrow, subcruciform ; valves joined to the 

 abdominal portion of the chest by sutures, the lateral teeth 

 of which are so large as to admit of but little motion, 

 especially in the posterior one ; wings long and narrow, 

 without any groove on the inner part. Tail unarmed. 



8. K. odorutum. From New York to Florida. 



9. K. guttatum. Testa ovali, dorso subtricarinato, fla- 

 vida fusca maculata, margine undique postice valde declivi, 

 minims expanso. Sterno flavescente, angusto, antice trun- 

 cate, postice late emarginato, femoribus et cruribus seriebus 

 pai5illarum latere interiore echinatis ; cauda mutica. Penn- 

 sylvania. 



As I have not seen the species here described as new, I 

 can give no opinion on their distinctness. A'. Pennsylva- 

 nicum, from the description of the young, is evidently the 

 species I have described under that name, but the other 

 descriptions do not appear to be intended for the new spe- 

 cies I have described ; at least the characters on wliich I 

 have founded the species are not observed. 



K. guttatum, which is described as subcarinate, is evi- 

 dently not the Aromochelys cai-inatum of this work. 



M. Leconte considers K. Doubledayii, from the descrip- 

 tion given, to he a distinct species.
