in the Gulf of St. Lawrence. 347 



Annelida. 



By far the most numerous of the denizens of the deep-sea 

 mud in the St. Lawrence are marine worms. Apparently 

 about 20 or 30 species were collected j but none of them has 

 as yet been studied or determined. 



Crustacea. 



Hempen " tangles " used in 212 fathoms water, to the south- 

 east of the east point of Anticosti, brought up several living 

 examples of a Pycnogonum, which is Dr. Stimpson's P. pelagi- 

 cuniy but which does not seem to differ from the P. littorale^ 

 Strom, of European seas. A fine specimen of Nymphon 

 giganteum^ Goodsir, was dredged in 125 fathoms off Cap- 

 Rosier lighthouse. On the authority of the Rev. A. M. 

 Norman's ' List of the Crustacea of the Shetlands/ I had quoted 

 this (in a report printed by the Department of Marine and 

 Fisheries for the Dominion) as Johnston's species ; but Prof. 

 S. J. Smith informs me that it was Goodsir who first described 

 it. Several examples of Munno2)sis ty2nca^ M. Sars, were 

 taken in 125 fathoms off Cap-Rosier lighthouse. Several 

 curious Amj)hipods were taken, among the more conspicuous 

 of which were fine specimens of an Ejnmeria^ which Mr. 

 Smith refers doubtfully to E. coniger of Boeck. No large 

 Decapods were dredged from deep water ; the only specimens 

 observed were a few shrimps. Mr. Smith recognizes the fol- 

 lowing critical forms of Macrura in a smaU series which I sent 

 to him for identification : — 



Pandalus annulicornis, Leach. 96 fathoms, Trinity Bay, 



and 125 fathoms off Cap-Rosier lighthouse. 

 Hippolyte Phippsii^ Kroyer, with the preceding species. 

 Hippolyte Fabricii^ Kroyer. 125 fathoms, off Cap-Rosier 



lighthouse. 

 Hippolyte polaris^ Kroyer. 38 fathoms, off Cap-Rosier 



lighthouse. 



POLYZOA. 



Good specimens of the following species have been deter- 

 mined, from depths of from 90 to 250 fathoms ; but many in- 

 teresting forms are at present unnamed: — 



Crisia eburnea, Linn. 

 Idmonea atlantica, Forhes. 

 Defrancia lucemaria ?, Sars. 

 Alcyonidium gelatinosum, Pallas. 

 Scrupocellaria scruposa, Linn. 

 Gemellaria loricata, Linn. 



Caberea Ellisii, Flem. 

 Bicellaria ciliata, Linn. 

 Acamarchis plumosa, Pallas. 

 Flustra Barleei, Busk. 

 Retepora cellulosa, var. 



elongata, Stnitt.
