Biriney on Terrestrial Mollnsks. 75 



Say's description is as follows. 



P. AVAUA. — Shell covered with nuniorous sliort, roV)ust hairs ; 

 spire convex ; whorls four, regularly rounded, with hardly elevated 

 lines forming grooves, wdiich are much more conspicuous near the 

 mouth ; mouth subreniform, two projecting, obtuse teeth on the 

 outer lip within, separated by a deep sinus ; outer lip elevated, 

 equal, describing two-thirds of a circle ; pillar-lip elevated, broadly 

 but not profoundly emarginate, concave beneath, and connected to 

 the inner side by an elongated, lamelliform tooth, which is placed 

 obli<|uely on the penultimate w'horl, near the middle of the mouth ; 

 lips almost equally prominent, continued ; umbilicus moderate, not ex- 

 hibiting the volutions, no groove on the penultimate whorl within it. 



Breadth quarter of an inch. Inhabits Florida. Cabinet of the 

 Academy. Animal longer than the breadth of the shell, acute 

 behind, above granulated and blackish, beneath, and each side, 

 white. 



This we found in the orange groves of Mr. Fatio, on the river 

 St. John, East Florida ; it is usually covered with a black, earthy 

 coat, which is probably retained and collected by the hairs. When 

 unencumbered with this vesture, the shell is of a horn-color. It is 

 by no means so common as the preceding species.
