through nearly the same set of forms as those there represented. 

 The Coccoliths agree with those figured in the same place exactly, 

 and also with those found in the English chalk and recent seas. 

 They are in a remarkably good state of preservation. The 

 average diameter of the larii;er among them is about -003 milli- 

 metres, which agrees very nearly with that of those found in 

 other places. Dr. Gumbel has discovered Coccoliths in lime- 

 stones of many ages, and they appear, though so minute even in 

 comparison with the Foraminifera, to have played no unimpor- 

 tant part in the fixation of calcareous matter, and the building 

 up of the crust of the earth. 



ON RECENT DEEP-SEA DREDGING OPERATIONS 

 IN THE GULF OF ST. LAWRENCE.^f^ 



By J. F. Whiteaves. 



During the summer of 1873, the Hon. the Minister of Marine 

 and Fisheries of the Dominion of Canada very kindly placed one 

 of the government schooners at my disposal, for dredging pur- 

 poses. These investigations, which were undertaken on behalf 

 of the Natural History Society of 3Iontreal, had, as their pri- 

 mary object, an examination into the present condition of the 

 Marine Fisheries of the Gulf, and w^ere supplementary to similar 

 explorations carried out by myself in the summers of 1871 and 

 1872. In the present paper, a short descriptive account will be 

 attempted of some of the most interesting zoological specimens 

 collected in 1873. Nearly nine weeks were spent at sea (from 

 July 18th to September 8th) ; and during this time, although 

 the weather was often unfavorable, we nevertheless got about 

 seventy successful hauls of the dredge. The cruises were 

 essentially four in number^ but on the whole the first yielded the 

 greatest number of novelties. 



Cruise 1. — The first two weeks were devoted to an examina- 

 tion of the deep water in the centre of the mouth of the river^ 

 between Anticosti and the Gaspe Peninsula. The most inter, 

 esting specimens were obtained in from 200 to 220 fathoms^ 

 mud ; and among them are the following :
