and a species of Pycnogonum. Several of the last-named crus- 

 taceans were taken at a depth of 250 fathoms, entangled on a 

 swab, fastened in front of a deep-sea lead, which was attached to 

 the rope, a few feet from the mouth of the dredge. This cir- 

 cumstance tends to show that the genus is not always parasitic in 

 its habits. The Decapods, Amphipods, &;c., at least those of 

 greatest interest, have not yet been identified. Among the most 

 noticeable of the marine Polyzoa are Defrancia truncataj and 

 what appears to be a Retepora. Not many species in this group 

 were obtained in very deep water, and those procured were, for 

 the most part, of small size. About six species of Tunicates were 

 collected. Beino; anxious to have Mr. J. Gwyn Jeffreys' opinion 

 upon the various species of Mollusca during his visit to Montreal, 

 I studied these carefully first, and submitted the whole of them to 

 him for examination. Twenty-four species of Testaceous Mol- 

 lusca were obtained at depths of from 90 to 250 fathoms. Nearly 

 all of these are Arctic forms, and eleven of them are new to the 

 continent of America. 



The following are some of the most interesting of the deep- 

 water Lamellibranchiata : — Pecfa grcenlandicus of Chemnitz, but 

 not of Sowerby ; * Area pectuncido ides Scacchi; Yold'ia luc'ida 

 Loveu ; Y.frigida * Torell ; Keoera artica ^ Sars ; N. Obesa^ 

 Loven. Among the novelties in the Gasteropoda of the same zone 

 are the subjoined : — Dentalium ahyssoruTn Sars ; Siphonodcnta- 

 lium vitreumSavs; Eidima stenostoma J e^reys ] Bel a Trevelt/ana 

 Turton*; Chrysodomus (^Sipho) AS^arsu Jeffreys.* Three Brachio- 

 pods occur in the Gulf, of which Rhi/nchonella j^sittacea and Tere- 

 hratella Sjntzhergensis are found in about 20 — 50 fathoms, and 

 Terebratula septentrionalis in from 100 — 250. A few rare shells 

 were obtained in comparatively shallow water; among them an 

 undescribed TelUna (of the section Macoma), a new Odostomia, 

 and Chrysodomus (^SijyJio') Spitzhergensis^ Beeve. Nor were 

 even the Vertebrata unrepresented; from a depth of 96 fathoms 

 off Trinity Bay, a young living example of the '* Norway Had- 

 dock " (^Sehastes Norvegiciis') was brought up in the dredge. And 

 off Charleton Point, Anticosti, in 112 fathoms, on a stony bot- 

 tom, two small fishes were also taken ; one, a juvenile wolf fish 



• I am indebted to Mr. Jeffreys for the identification of species to 

 Which an asterisk is attached. He corroborates also my determina- 

 tion of the remainder.
