K. odoratum. Testa elliptica valde convexa, dorso plus minus carinato (inter- 

 dum medio depresso piano) postice valde declivi, margine angusto minime dis- 

 panso', scutis vertebralibus imbricatis, primo ad nuchale et marginalis primi 

 dimidium apposito, scuto postremo quinquangulari ad marginale postremum 

 solum apposito, scutis mavginalibus duobus postremis caeteris valde latioribus. 

 Sterrio testa multo angustiore, lobo anteriore posteriore mobiliore, interdum 

 tamen amHobus fixis.

It is remarkable how this species has been shifted from one genus to another, 

 until it may be found arranged under six different genera, and divided into four 

 species. It does vary considerably as regards the mobility of the sternum, and 

 the form of the dorsal pottion of the shell, which although generally carinate is 

 sometimes perfectly flat in the middle; specimens in all respects intermediate 

 may be found. The anterior valve of the sternum cannot be moved more than 

 so as to form an angle of 20 with the abdominal line, the posterior much 

 less. 



K. guttatum. Testa ovali, dorso subcarinato; flavida fusco maculata, mar- 

 gine undique, postice valde declivi, minime dispanso. Sterno fiavescente, angusto, 

 antice truncato, postice late emarginato, femoribus et cruribus seriebus papillarum 

 latere interiore echinatis. Cauda mutica. 



Hah. in Pennsylvania ; Prof. Baird. 



Head and neck dusky brown, varied with yellow on the front and cheeks, jaws 

 yellow with a few shades of dark brown ; the upper one not hooked, the margin 

 scarcely sinuate, chin with four small warts. Legs dusky, furnished with the 

 usual plicas and scales, the femora and tibiae with a small area on the inner side of 

 each, echinate with rows of small pointed papillae. Tail with six rows of 

 pointed papillae, unarmed at the end. Shell yellowish, exactly elliptical, convex, 

 declivous on all sides, nearly perpendicular behind, subcarinate on the vertebral 

 line ; spotted with dark brown particularly on the upper part. Vertebral scuta 

 imbricate, the first triangular with the ap?x truncate and the base nearly straight, 

 applied to the nuchal and more than half of the first marginal, second, third and 

 fourth urceolate, hexagonal, the upper face emarginate, the lower rounded, the 

 fifth pentagonal, the upper face narrow and emarginate, the two basal faces 

 incurved and applied only to the last marginal. First lateral, large, unequally 

 four sided, the lower side curved, and three times as long as the upper, second and 

 third pentagonal, fourth quadrangular, the posterior lateral angle widely emar- 

 ginate by the curved upper side of the penultimate marginal, so as to uive the 

 figure another side; nuchal plate small linear, the othpr marginals oblong four- 

 sided, nearly equal, except the two last which are much higher, and nearly equal, 

 their uppor faces curved Sternum yellow, narrow, wings very much produced, 

 before truncate and entire, behind widely emarginate, valved as in the last. 

 Gular plate small, irregularly triangular, pectorals four angled, all the sides more 

 or less curved, the posterior lateral angle projecting a little beyond the next 

 scutum, brachials four sided, the upper side concave, the outer convex. Abdo- 

 minals four sided, wings lonj; and narrow, axillary and inguinal plates semi- 

 oval, the first produced anteriorly, the other posteriorly to a point ; femorals 

 triangular, the apex widely truncate, the posterior exterior angle projecting be- 

 yond the next scutum which is four sided; the upper side oblique inwardly, the 

 lower concave. 



Length 3.8, breadth 2.7, height 1.-15. Sternum length 2.6, breadth at the valve 

 1.4, tail 1.5.
