chap, in.] THE CRUISES OF THE 'PORCUPINE: 97 



Echinodermata.— 0/;7//otfferc sericeum, Foebes ; 

 several well-grown specimens. 

 JEchinocucumis typica, Saes. This seems to be a 

 very widely distributed species ; we got it in 

 almost all our deep dredgings, both in the 

 warm and in the cold areas. 



A remarkable stalked ci'inoid allied to Rhizocrimis, 

 but presenting some very marked differences. 



Polyzoa. — Salicornaria, sp. n. 



Ccelenterata. — Two fragments of a hydroid 

 zoophyte. 



Protozoa. — Numerous foraminifera belonging to 

 the groups already indicated as specially charac- 

 teristic of these abyssal waters ; together with a 

 branching flexible rhizopod, having a chitinous cortex 

 studded with globigerinse, which encloses a sarcodic 

 medulla of olive-green hue. This singular organism, 

 of which fragments had been detected in other dredg- 

 ings, here presented itself in great abundance. 



One or two small Sponges, which seem to be 

 referable to a new group. 



On Friday, July 23, we tried another haul at the 

 same depth ; but when the dredge came up at 1.30 p.m. 

 it was found that the rope had fouled and lapped right 

 round the dredge-bag, and that there was nothing in 

 the dredge. The dredge was sent down again at 3 p.m., 

 and was brought up at 11 p.m., with upwards of 

 2 cwt. of ooze. — We got from this haul a new 

 species of Pleurotoma and one of Dentalium; 

 Scrobicularia niticla, Mullee ; Dacrydium vitreum, 

 Toeell; Opliiaccmtha spimdosa, M. and T. ; and 

 Ophiocten kroyeri, Lutken ; with a few crustaceans 

 and many foraminifera. /
