Fig. 38. Eirafaicllina remota, a, view of the spire ; h, oblique view of anterior side. 



Description. — Shell small hemispherical, spire depressed and rounded 

 in outline ; height, two to three lines, width three to four 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 four lines wide, the width of the aperture is 

 about one and one-half lines, as nearly as can be determined from an indi- 

 vidual party buried in the matrix. Surface nearly smooth. 



Occurs at Smith's Sound, Trinity Bay.

*" Hyolithes EXCELLENS. (N. sp.) 



Description, — Shell usually about two inches in length, tapering 

 at the late 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 projecting parts 

 of the sides are about one-third the height ; above this the sides are 

 gently convex, the dorsum more narrowly rounded. The shell is thin, 

 nearly smooth, with very fine obscure striae, about ten in one line. 

 The striae curve forwards on the ventral side, forming an arc the height of 

 which is equal to about one-third the width of the shell. On crossing the 

 lateral edges the strij« curve backwards, until they reach the most project- 

 ing part of the sides, then cross up and over the dorsum at a right angle.
