Hab. Gulf of Suez. 
Very similar in form to the succeedin ng species; but the 
axis is not perforated, the inner sd is hardly reflexed, and the 
whorls are angulated at the sutures

Hab. Gulf of Suez. 
A pretty shell, more nearly resembling the type of Hyala 
than any other form with which I am acquainted, but the 
true position of which must remain doubtful until the animal 
shall have been discovered and examined. 
3. H. pumila, A. Ad. 
H. testa elongato-turbinata, imperforata, alba, wity pellucida ; spits

Hab. Gulf of Suez (M'Andr.), Japan (A. Ad.). 
This pretty little shell, which — to be identical with 
specimens I found in Japan, resembles in form some species 
of Onoba, but is smooth and nearly pellucid, and has the ob- 
tuse spire seen in Hyala. The inner lip being continuous 
A the outer, also, reminds one rather of Onoba than o 
Yala.
