604 EDGAR A. SMITH. 
Family HARPIDAE. 
59. Harpa ventricosa, Linn. 37,/. IX. 
60. Harpa minor, Lamarck, 37,/. IX. 
A specimen captured by Mr Gardiner at station I. has the hinder portion of the foot detached. 
Judging from the large size of the separated portion, the animal apparently divested itself of it, 
being unable to withdraw this bulky appendage within the shell. Or, may it not be cast off as 
a peace offering to any fish or other predatory creature who attacks the helpless Mollusc? 
Family MARGINELLIDAE. 
61. Marginella picturata, Nevill, var. Pl. XXXV. figs. 3, 4 (JZ. picturata, Weinkauff, 43). X. 
The two specimens which I believe to be a variety of this species differ from the type in 
having the outer lip strongly denticulate within, in one example the denticles numbering thirteen, 
in the other only nine. Both are of a fleshy tint, with two white narrow zones with reddish- 
brown spots upon the penultimate whorl, and three upon the last, one at the suture, one at the 
shoulder, and one towards the base, all terminating upon the thickened labrum in a red _ spot. 
Between the second and third zones there are three or four transverse lines of pinkish red colour 
and the extreme tip of the spire is also reddish. The brown spots upon the narrow white zones 
are small and might be described as cross lines rather than spots.

The two specimens obtained by Mr Gardiner differ considerably from all the figures given of 
this species. They are much more slender, and the upper part of the shell above the white zone
