Deal Voe, Shetland [Jeffreys] ; ' Triton ' exped., 1882, 

 St. 13, lat. 59° 51' N., long. 8° 18' W., 570 fathoms ; 

 ' Knight Errant; 1880, St. 7, lat. 59® 37' N., long. 7° 19' 

 W., 530 fathoms; off south of Ireland, 1000 fath., ' Flying 

 Fox,' 1889 [E. A. Smith). 



Its extra-Britannic range is ' Porcupine,' 1870, Stat. 16, off 

 Portugal, 994 fathoms ; ' Travailleur,' 1880, Bay of Biscay ; 

 ' Washington,' 1881, Mediterranean, 337-464 fathoms ; 

 ' Challenger,' 350-1000 fathoms, off the Azores ; off Culebra 

 Island, West Indies ; off Pernambuco ; by G. 0. Sars off 

 Lofoten Islands, 300 fathoms ; Straits of Florida, 150-465 

 fathoms [Dr. Rush) ; east coast of North America, 124-400 

 fathoms [DaU). 



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 striafula, Forbes = Bulla conulus, Wein- 

 kauff=5. [Cylichna) Hoernesi, Weinka.uf^= C. cuneata, 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 Dall 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. umbilicata 

 and 1\ nitidula, which Sars has shown by examination of 

 the masticatory apparatus are true Tornatince. 



[In the Report 'Porcupine' Exped., 1869 (Proc. Royal 

 Soc), Jeffreys gives under St. 42 ^^ Cylichna pyramidata 

 (Norwegian and Mediterranean) ; " and in B. C. v. p. 223,
