Astarte lactea of Brod. and Sowerby. Crustacea are peculiarly 
plentiful on this bank, particularly the two species of Hyas ; 
Eupagurus; Pandalus annulicornis ; Crangon boreas ; Nectocran- 
gon lar (fine); Hippolyte spina ; +H. Phippsii ; and +H. pusiola. 
e Amphipods are represented by Acanthozone cuspidata 
(Lep.); Tritropis aculeatus (Lep.) ; and Eusirus cuspidatus. The 
Isopods by Jdotea marmorata Packard, and by a Bopyrus which 
was found burrowing under the carapace of the common Pan- 
dalus. A small species of Nymphon was also dredged here. 
At the end of the third day a stiff breeze from the southwest 
sprung up, accompanied with rain, and in consequence of this 
we made for Miscou Island for shelter. As soon as the gale 
moderated we proceeded to the Bradelle Bank, and on our way 
mon on both banks. Astrophyton Agassizii ; Ophioglypha Sar- 
su, large; Q. nodosa ; and Psolus phantapus are frequent on the 
Bradelle, where also a fine living specimen of Ophiocoma nigra 
‘iiller was obtained. The Crustacea of both banks are for the 
ee similar, but on the Bradelle a few additional species 
cheirus pinguis ; +Harpina, sp. ; + Paramphithoé pulchella Bruz. ;
