gneiss, &c. Soft-bodied organisms are peculiarly plentiful oa 

 this bank. The most characteristic of these are Alcyonium ruhi- 

 forme Ehr., small varieties of Urticina crassicornis ; Asc'idiop- 

 •sis complanatus, oi unxxsVidX size and abundance; various other 

 Tunicates ; and quantities of common Ophiurids and Asterids„ 

 '\ Metopa glacialis Boeck, was occasionally met with between the 

 inner and outer tunic of Ascidiopsis. The stones are often 

 covered with encrusting sponges, of two or three species : Gran- 

 tia ciliata was frequent, and with it there occurred another 

 calcareous sponge which Prof. Verrill has identified as the 

 Ascort is fra gills of Haeckel. Hydrozoa and Polyzoa are exceed- 

 ingly abundant on this bank; the former seem to be mostly 

 common northern forms. Among the latter, Myriozoum suh- 

 gracile D'Orb. ; CeUepora scabra Fab. ; Eschara cervicornis f 

 Pallas; Cahereti EUisii ; and other species, were fine and frequent- 

 Two fine specimens of Forella Icevis (Fleming) were dredged at 

 this locality. ^ Bol tenia ciliata Moller ; ^ Molgida pannosa 

 v.; Cynthia pyriformis (Rathke) ; and C. monoceros Moll., 

 occurred sparingly among the other Tunicates. 



Among the Echinoderms are Pteraster militaris, Asferias 

 Grctnlandicus, and Psolus pliantapus. The rarest of the Orphan 

 Bank Mollusca are Amicula Emersonii (Couth.), fine and fre- 

 quent; Mamma immaculata (Totten) ; Trophon craticidatus 

 (O. Fab.) ; Buccinum tenue Gray ; Neptunea Spitzhergensis 

 ^Reeve) ; Tritonofusns Kroyeri Moll. ; Astyris HolholUi Beck ; 

 and a few Astarte lactea of Brod., and Sowerby. Crustacea are 

 peculiarly plentiful on this bank, particularly the two species of 

 Hyas ; EnjKigurus ; Pandalus annidicornis ; Crangon horeas \ 

 Nectocrangon lar (fine); Hippolyte spina; '\ H. Phippsii ; and 

 "fS. pusiola. 



The Amphipods are represented by Acanthozone cuspidata 

 (Lep.) ; Tritropis aculeatus (Lep.) ; and Eusirus cuspidatus.. 

 The Isopods by Idotea may^iorata Packard, and by a Bopyrus 

 which was found burrowing under the carapace of the common 

 Pandalus. A small species of Nymplion 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 

 made one cast of the dredge between it and Miscou. In this 

 haul, specimens of f Hippolyte macilenta ; f Pseudomma, noVo .
