 gin is stouter and the teeth stronger than in A. tener, and different in 

 relative size and proportions; the ligament-plate is also longer.

Gasteanella Yerrill. 



American Journal of Science, vol. iii, p. 286, 1872. 



" Shell oblong, more or less irregular, and sometimes with the ven- 

 tral margin inflexed; pallia! sinus large ; ligament external, elongated. 

 Right valve Avith two small cardinal teeth ; the posterior one thin, 

 directed obliquely backward. Left valve with two cardinal teeth ; the 

 posterior one stout, bilobed ; the anterior one smaller. Xo distinct lat- 

 eral teeth. Animal with long, slender, separate siphonal tubes, with a 

 simi)le circle of papilhe at the ends ; mantle well open anteriorly ; foot 

 ligulate. The curious little shell for which this genus is constituted 

 apparently resembles Gastrana more than any other described genus."

 Shell small, variable in form, swollen above, more or less elongated 

 oval, or oblong, with rounded ends, compressed posteriorly. The beaks 

 are rounded, somewhat prominent, incurv^ed but not approximate, and 

 directed somewhat forward ; the anterior dorsal margin is deeply concave 

 in front of the beaks, but without a distinct lunule, at the anterior end 

 regularly rounded or a little prolonged, compressed ; ventral margin 

 slightly convex, or nearly straight and sub-parallel with the dorsal mar- 

 gin, or incurved, in the different specimens ; jiosterior end broadly 

 rounded in some, decidedly prolonged in others; dorsal posterior mar-
