Lofoten Islands, 300 fathoms ; Straits of Florida, 150-465 
fathoms [Dr. Rush) ; east coast of North America, 124-400 
fathoms [Dali). 
It occurs fossil in the Coralline Crag of England. 
Jeffreys says that it is not the Bulla conulus of Deshayes. 
I have no opportunity here of consulting that work. It is 
certainly not Bulla striatula, Forbes = Bulla conulus , Wein- 
kauff=R. [Cylichna) Hoernesi, Weinkauff = C. cuneat a, Ti- 
beri, which I have from Algiers and Palermo. That is a 
larger shell, remarkably attenuated above, with deeply in- 
verted spire, which is quite open above (the margin of the 
last whorl not projecting over the edges of the inversion as in 
T. ovata)) and the shell strongly striated vertically, especially 
at the apex. 
Nor is it Diaphana conulus , Brugnone, which Dali states 
is the Cylichna obesiuscula , Brugnone. It is to this last 
species moreover, according to him, that the shells found by 
Seguenza in the Italian Pliocene really belong, and not to 
T. ovata , to which they were referred by Jeffreys. 
I have followed Sars in placing the species in the present 
genus as its characters come near to those of T. umhilicata 
and T. nitidula , which Sars has shown by examination of 
the masticatory apparatus are true Tornatince.
