another, and sometimes vividly illuminating the whole 
outline of the star-fish. 
On the 27th we dredged in 862 fathoms (Station 42), 
the weather being still very fine, and the sea quite 
smooth. The bottom was ooze, with sand and dead 
shells. Among the Mollusca procured were a new 
species of Pleuwronectia, Leda abyssicola (Arctic), Leda 
messinensis (a Sicilian tertiary fossil), Dentalinm 
gigas (sp. n.), Siphonodentalium (sp. n.), Cerithium 
metula, Amaura (sp.u.), Columbella haliweti, Cylichna 
pyramidata (Norwegian and Mediterranean), and 
many dead shells of Cavolina trispinosa. These 
latter were very common in all the northern dredg- 
ings, though we never saw a living specimen on the 
surface. 
During the afternoon we took a series of inter- 
mediate temperatures, at intervals of 50 fathoms, from 
the bottom at 862 fathoms to the surface. 
On the 28th we dredged in 1,207 fathoms (Station 
43), with a bottom of ooze. <A large Fusus of a new 
species (/". attenuatus, Jeflreys) was brought up alive, 
with two or three Gephyrea, and an example each of 
Ophiocten sericeum and Kehinocucumis typica. We 
again dredged on the 29th and 380th, gradually draw- 
ing in towards the coast of Ireland in 865, 458, 180, 
and 113 fathoms successively (Stations 44, 45). In 
458 fathoms (Station 45) we procured a broken 
example of Brisinga endecacnemos, previously taken 
by Mr. Jeffreys off Valentia, and a number of 
interesting Mollusca; and in 458 and 180 fathoms 
(Stations 45 and 45a) an extraordinary abundance of 
animal life, including many-very interesting forms—
