Pleurotoma carinata, Jeffreys, Brit. Conchol. vol. v. p. 221, pi. cii. 



fig. 7. 

 Spirotropis carinata^ G. O. Sars, /. c. p. 242, pi. xvii. fig. 5 o, 6 (figura 



bona). 



Dredged by Dr. Jeffreys and myself N.N.W. of Unst, 

 Shetland, in 120 fathoms, living. ' JPorcupine,' 1869, " N. of 

 Hebrides, 189 fath." * 



I have dredged it frequently in the Norwegian fiords, and 

 it occurs in the Mediterranean. By the ' Travailleur ' it was 

 obtained off the coasts of Spain, Portugal, and Marocco, and 

 as far south as the Canary Islands {Locard). 



Genus 4. Drillia, Gray. 



1. Drillia semicolon (Searles Wood). 



Pleurotoma semicolon (J. Sow. ?), Searles Wood, Crag MoU., Univalves, 



p. 54, pi. V. fig. 3. 

 Pleurotoynn galerita, Jeffreys, Brit. Conch, v. p. 221, pi. cii. fig. 6. 

 Pleurotoma semicolo)}, Monterosato, Nuova Revista delle Conch. 



Medit. 1875, p. 42. 



Jeffreys (Brit. Conch, v. p. 221) writes: — "A fresh but 

 dead specimen of P. galerita, Ph. (P. galeritum, Moll. Sic. 

 ii. p. 172, t. xxvi. fig. 15), was dredged by Carpenter and 

 Thomson in 189 fathoms, about 50 miles N. of the Butt of 

 Lewis. It is a very rare Calabrian fossil." Philippi's 

 figure, however, does not at all resemble that of Jeffreys, and 

 Monterosato writes: — "II P. galeritum, Ph. = subasperum, 

 Brugnone, fossile di Calabria e di Sicilia, b differente." 

 Mediterranean, 50-100 fath. {Jeffreys, dredgings of Capts. 

 Spratt and Nares). 



Genus 5. H^dropleura, Monterosato MSS. 



(Bucquoy, Dautzenbeig, and G. Dollt'us, Moll. Marins 



du Roussillon, p. 110). 



1. Ilccdropleura septangularis (^lontagu) ,^ Pleurotoma sept- 

 angularisy Jeflr. 



This species, which is operculated, cannot be retained in 

 the same genus with the inoperculated Mangilice. 



Genus 6. Mangilia, Risso. 



1. Mangilia striolata (Scacchi). 



2. Mangilia attenuata (Montagu). 



• This exact depth is not ^ivon for nny station; probacy Stat. 86, 

 190 fathoms. I have a pood living specimen, dredged by the ' Porcupine ' 

 and given me by Sir Wyville Thomson.
