No. 5.] WHITEAVES — DEEP-SEA. DREDGING. 259 



species has not yet been taken in the Gulf. Cornulariella mo- 

 desta Verrill, was collected (in 1871) at depths of 220 fathoms^ 

 between the east end of Anticosti aud the Bird Rocks. 



EcHiNODERMATA. — Schizasfer fragilis Dub. & Koren, and 

 Vtenodiscus cris2}atus, are common in the deep-sea mud, as are 

 also Ojyhiacantlia spinidosa M. & T., and an Amphiura whose 

 specific relations are still obscure. The Ophiuridae collected 

 during this cruise have yet to be studied. One living example 

 of * Oj)hioscolex glacialis M. and T. was dredged in 210 fathoms, 

 txi the southwest by south of the Southwest Point of Anticosti. 



PoLYZOA. — A beautifully perfect specimen of Flustra ahi/ssf- 

 cola of G. 0. Sirs, showing the singular avicularia, so character- 

 istic of the species, was dredged in the centre of the mouth of the 

 river, at a depth of 220 fathoms. Two examples of Honiera 

 iichenoidcs (Linn.) and one of a peculiar variety of Bug nla jduni- 

 osa? were dredged in the same place. Escharella palmata (M. 

 Sars) was also sparingly taken in deep water. 



MoLLUSCA. — The most abundant species collected at greater 

 depths than 150 fathoms are Pecten Groenlandlcns Ch., and Area 

 pectuncAiloides ; but Fortlandia luclda, F.frlgida, Fhdine quad- 

 rata, Ci/Jichna nmhilicata Mont., Dentalimn attenuatum^ f Say, 

 and SiplwnodentaJlinn vitreum Sars, also occurred, though more 

 sparingly. Two living speciment of Cerifhiopsis costidata Moll. 

 (the B'lttiam arcticum of Morch) were dredged in the 220 fathom 

 locality. 



Crustacea. — The deep-sea Crustacea are of unusual interest. 

 Among them is a living specimen of Calocaris MacAncfreije Bell, 

 the first, I believe, that has been observed on the American side 

 of the Atlantic. In the same region, four specimens of a crust- 

 acean were collected, which belono- in my iiidument, to a new 



Note — lam indebted to Prof. Verrill for the identification of 

 several critical species, to whose names an asterisk (*) is prefixed; 

 aud the difficult Crustacea, whose appellations are preceded by a 

 •dagger (f), were kindh' determined for me by Mr. S. I. Smith. 



* If the shell described by the late Dr. Gould as D-intaliuvi dentale 

 •lae really the Dentaliuvi attenuatum of Say, the latter name is miicli 

 .prior to Stimpson's D. occidentale. Having received a number of Nor- 

 wegian specimens of D. abyssorum Sars, through the kindness of Mr. 

 -Jeffreys, and compared them with the St. Lawrence longitudinally 

 ribbed species, I cannot see any differences which in my judgment 

 are sufficient to separate them. At the same time, Dentalium striolafum. 

 St. seems to me a perfectly distinct and good species.
