The figure is said to be highly magnified, but the dimensions 
are not given.

C. QUADRATA, Reeve. PI. 18, fig. 31.

Described by Reeve without locality. His figure is three 
times the size given above, but there are good reasons for sup- 
posing it to be magnified ; among them, is the fact that Prof. C. 
B. Adams: obtained a shell in Jamaica which, except for its 
diminutive size, exactly corresponds with Reeve’s figure. He 
proposed to call his species M. diminuta, in case it should prove 
distinct. My specimens confirm his suspicion and Krebs’ con- 
viction that the two species are identical. 
C. ANGULIFERA, Reeve. PI. 18, fig. 22. 
Body-whorl biangulated, the upper and lower parts chestnut, 
the middle yellowish. 
West Indies. 
Dimensions not given, but greatly magnified in the figure. 
C. MONILIFERA, Sowb. PI. 14, fig. 9; Pl. 18, fig. 43. 
Shell minutely reticulated; white, tessellately painted with 
squares, each composed of four short parallel brown lines. 
Length, 5 mill. 
West Indies. 
Described as a Columbella, and included in that genus in the 
“ Manual,” v, p. 149; the figure, however, shows the Pleurotomid 
notch. P. scalpta, Reeve (Pl. 18, fig. 43), and P. fuscolineata, 
C. B. Ad., are synonyms.
