end. The shape of the lips is doubtful, owing to the injuries that they have 
sustained. The anterior portion of the hack seems to have been triangular. The 
ventral surface is not re-entrant, but flattish and only slightly convex. The 
dorsal surface is moderately convex. The anterior part is broken, but appears to 
have borne a median ridge and four lateral ridges, which disappear in the posterior 
half. The whole surface of the shell bears numerous fine transverse ridges. After 
the termination of the animal inside, the shell is produced into a thin point 
4 mm. long. The embryonic shell resembles Pelseneer’s figure (/. ¢., pl. IL, 9) of 
Clio sulcata rather than Clio australis, 
The foot, wings and other portions of the animal protruded from the shell are 
yellow, the viscera reddish. The wings are ample, about 6 mm. long and 5 mm. 
wide, deeply bi-lobed and with wavy edges. 
The interior of the liver is deep red. The stomach contains four large plates, 
bearing a conspicuous Y-shaped ridge on the outside. There also appears to be a 
fifth plate, smaller, indistinct and triangular, as well as a double row of minute 
plates. The radula is tri-seriate. The sides of the teeth are somewhat irregular 
and indented, but not serrulated. 
I think that these specimens belong to the Clio sulcata of Pelseneer, 1. ¢., but 
feel some doubt whether that species is really identical with Pfeffer’s Cleodora 
suleata. 
To the same species are probably referable a small Clio, to which fragments 
of shell are attached and two posterior ends of shells, one of which bears 
remarkably large and distinct transverse furrows. They are all labelled

The labels state that the numerous specimens representing this form were all 
captured at Winter Quarters in from three to ten fathoms, the great majority at 
the latter depth. They fall into two classes, chiefly distinguished by their colour, 
some being yellowish and generally well expanded; others, brownish or greenish 
grey, and much more contracted. These differences seem due to the method of 
preservation rather than to natural variations, and the labels make it probable that 
the yellowish specimens were killed with picric acid. 
The measurements of a large specimen are: length, 17 mm., breadth of the 
body at its thickest part, 6 mm., breadth across the fins, 9 mm. The colour is 
usually a pale lemon yellow (probably representing an original white), sprinkled 
with round dots of opaque yellow. The number of dots varies greatly, but they 
are entirely absent in comparatively few individuals. They are much more
