derstand Mr. Davidson, what appears to be aa aperture, in the 

 apex of the ventral valve, is not truly such, but an impression 

 made in the cast of the interior by a tubercle on the inside of the 

 shell.

Fig. 7. Straparollina remota, a, view of the spire ; oblique view of 

 anterior side. 



Shell small hemispherical, spire depressed and rounded in out 

 line, height 2 to 3 lines, width 3 to 4 lines, whorls about three, 

 suture deep. The whorls are nearly uniformly rounded, more 

 narrowly so on the upper side close to the suture, and also on the 

 basal side. On a side view the minute apical whorl is scarcely 

 at all seen ; the next below it is elevated about half its own 

 diameter above the body whorl. In a specimen 4 lines wide, the 

 width of the aperture is about 1 J lines, as nearly as can be deter- 

 mined from an individual partly buried in the matrix. Surface 

 nearly smooth. 



Occurs at Smith's Sound, Trinity Bay.

 dorsal side of b is too broadly rounded. 



Hyolithes excellens, spec. nov. 



Shell usually about two inches in length, tapering at the rate 

 of between four and five lines to the inch. The ventral side is 

 nearly flat or very gently convex; the lateral edges narrowly 

 rounded, in some specimens rounded angular ; the most project- 

 ing parts of the sides arc at about one-third the height ; above
