Several entire and perfectly fresh specimens, some living, occurred 
at station 894. Other specimens were taken at 891 and 947. At 
one station many living specimens were obtained in the trawl-wings, 
presumably, therefore, from close to the bottom.

Plate XLII, figure 19. 
A line, large specimen (fig. 19), probably belonging to this species, 
but with the apex broken, was dredged by the party on the “ Bache,” 
in 1873, in the Gulf of Maine (station 12 b), in 60 fathoms, mud. 
Another specimen, with the apical notches complete, and 10""" 
long, 2 •5""" broad, was dredged in the Gulf of Maine, 107 fathoms 
(station 9 b), 1K73. 
Off Martha’s Vineyard, at stations 892, 949, 994, in loo to 487 
fathoms, specimens were taken that probably belong to this species, 
but the apex is broken in every case.
