Buccinum undatam (L.). E. S. Morse has observed in the harbour of 
Eastport that the male specimens are much smaller [about 21-25 mm. 
in length] than the females [40-45 mm.] ; as these animals live there on 
a ledge partly exposed at low tide, hid away in rocks and concealed in 
the cracks and crevices, only males of small size can work their way out 
and unite with the females in such restricted quarters. P. Bost. Soc. 
xviii., pp. 284-287. 
Buccinum grcenlandicum (Chemn.) : its radula, somewhat different from 
that of B. undatum ; Hogg, P. R. S. xxv. p. 201.

Canidia (H. Adams) and G/ea (H. Adams) : operculum unguiculate, radula

n. recidiva, recent shells dredged near the Cape Verde Islands ; Martens, 
JB. mal. Ges. iii. pp. 239 & 246, ph ix. figs. 3 & 10. 
Nassa corniculum (Olivi) is a true Nassa ; and an inaccurate figure of

for it the sub-genus A mycZa ; id. 1. c. p. 249.
