FIAP. in.] THE CRUISES OF THE l PORCUPINE: 97 



; ECHINODERMATA. Ophiocten sericeum, FORBES ; 



several well-grown specimens. 

 Echinocucumis typica, SARS. 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 crinoid allied to Rhizocrinw, 

 ut presenting some very marked differences. 

 POLYZOA. Salicornaria, sp. n. 

 CCELENTERATA. T\vo fragments of a hydroid 

 >ophyte. 



PROTOZOA. Numerous foraminifera belonging to 



te groups already indicated as specially charac- 



firistic of these abyssal waters ; together with a 



ranching flexible rhizopod, having a chitinous cortex 



judded with globigerinae, which encloses a sarcodic 



]edulla of olive-green hue. This singular organism, 



( which fragments had been detected in other dredg- 



igs, here presented itself in great abundance. 



One or two small SPONGES, which seem to be 

 iferable to a new group. 



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

 sme depth ; but when the dredge came up at 1.30 P.M. 



1 was found that the rope had fouled and lapped right 

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

 1 3 dredge. The dredge was sent down again at 3 P.M., 

 ad was brought up at 11 P.M., with upwards of 



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

 secies of Pleurotoma and one of Dentalium ; 

 Qrobicularia nitida, MTJLLER; Dacrydium vitreum, 

 IRELL; OpMacantha spinulosa, M. and T. ; and 

 t'hiocten Jcroyeri, LUTKEN ; with a few crustaceans 

 a :1 many foraminifera.
