Ofl' Martlia's Vineyard, station 1143, in 452 fathoms, soft mud, 

 1882. One specimen. 



The affinities of this shell are doubtful, as the animal and oj)ercu- 

 luni are both unknown. The sculpture resembles that of some 

 Pleurotomidje.

This species is rather common in our deeper drcdgings. 



It ao-rees very well with Sars's descriptions and figures. Among 

 our numerous sfftcimens there is considerable variation in form, 

 and in the number and prominence of the thin elevated ribs. 



It occurred at station 2035, in 1362 fathoms; sta. 2037, in 1731 

 fath. ; sta. 2(^38, in 2033 fath. ; sta. 2041, in 1608 fatli. ; sta. 2042, in 

 55 fath. ; sta. 2043, in 1467 fath. ; sta. 2076, in 900 fath. ; sta. 2084, 

 in 1290 fath.; sta. 2096, in 1451 fath.; sta. 2115, >iu 843 fath. 



It was most abundant at sta. 2038, N. lat. 38° 30' 30", W. long. 

 69° 08' 25", in 2033 fath., twenty specimens (No. 34,847) ; sta. 2076.
