THE VOYAGE OF H.M.S. CFIALLEHGEE. 
Eiijiliione, n. gen. 
Ewphione elisahethce , n. sp. (PI. IX. fig. 3 ; PL XVII. fig. 7 ; PI. XYIII. fig. 10 ; PI. 
VIIIa. figs. 3-6). 
Habitat . — Dredged at Station 142 (soutfi of the Cape of Good Hoj)e), December 18, 
1873; lat. 35° 4' S., long. 18° 37' E,; deptli, 150 fathoms; bottom temjDerature 47°'0, 
surface temperature 6 5° ’5 ; green sand. 
Length about 35 mm., breadth at the widest part (including bristles) 23 mm. 
A large and remarkable form, the stalked and rotate papillae giving the back a 
characteristic appearance. The body is broadly fusiform or nearly elliptical in outline, 
and is only a little less elevated ventrally than dorsally. 
The head somewhat resembles that of Lepidonotus. The eyes occupy the postero- 
lateral border of the head, and are so close as to be almost connate. They are nearer 
each other and much less distinct than those of IjjJiione muricata. The tentacle is of 
moderate length, reaching a little beyond the palpi, and narrows below the distal enlarge- 
ment from which the filiform tip proceeds. The two latter parts are whitish while the 
column is greyish. The antennae are of similar colour and shape, and are proportionally 
lone;. The tentacular and dorsal cirri follow the same outline, and the constriction 
below the swollen tip is in all well shown. The palpi are covered by a series of long 
conical papillae which give them a very hirsute appearance (under the microscope). 
These papillae show a crenated internal region, and the tip is in many furnished with a 
palpocil. They are continued to the tip of the organ, though the distal j^apillae are short. 
All the cirri have a dense cuticle, except at the tip, and though many adventitious 
structures {e.g., mud and sponge-spicules) are attached, their surface is quite smooth. 
The ventral cirri are subulate and projDortionadly large. The ventral papillae (or 
mamillse) are much more prominent than in l 2 )liione, but somewhat less tlian iii Lepi- 
donotus. They become distinct on the seventh foot, as in the latter. The mouth 
opens on the ventral surface as in Lepidonotus. 
The scales are thirteen in number on each side, and therefore the same as in Iphione, 
but their texture is flexible and leathery, and their surface is studded with warts or 
papillae as in Lepidonotus. The first scale is rounded, the rest more or less elongated 
transversely, so that the general shape is rhomboidal — ^the anterior edge, however, being 
incurved, and the posterior convex. The most characteristic feature is the presence of 
the peculiar rotate papillae on their surface, some being small and adpressed, others large 
and elevated on a pedicle. These processes occur mostly on the inner region of the scales, 
the outer border being occupied by softer elongated spinose papillae, which in shape 
somewhat resemble a prickly pear. Continuing along the border inward these 
gradually merge into irregularly rotate forms. The latter marginal papillae are much
