350 Mr. J. F. Whiteaves on Deep-sea Dredging 



Jeffreys's greater experience, however, I keep the two forms 

 separate. N. arctica has not previously been found on the 

 American coast. 



* Utriculuspertenuis^ Mighels. In 25 fathoms, sand, off Trinity- 

 River, also in Gasp^ Bay ; abundant at both localities. 

 (Probably = U. turritus^ Moller.) 



Utriculus hyalinus'^j Turton {=D{aphana debilis^ Gould). 

 With the preceding, but rare in both places. 



^Pliiline quadrata, Wood. Alive, from 212 fathoms, mud, to 



/ the S.S.W. of the east point of Anticosti. 



Philine Uneolata^ Couth. Gaspd Bay, and off the St. John's 

 E-iver, Mingan, in 50 fathoms. 



I)entalmm ahyssorum^ Sars. Dead but good specimens of this 

 specieswere dredged in three localities: — inl64fathoms,mud, 

 off Seven Island Bay; also in 160 and 200fathoms to the S.W. 



., and S.S.W. of Ellis Bay, Anticosti. New to America. 



Siphonodentalium vitreum^ Sars. Deep water, in several lo- 

 calities, fine and living. Most frequent in 200 to 250 

 fathoms ; also new to the American side of the Atlantic. 



Margarita argentata^ Gould (=J/. glauca^ Moll.). Off the 

 mouth of the St. John's River, Mingan, in 50 fathoms, and 

 sparingly in other localities. Gaspe Bay. 



Margarita striata ?, Brod. & Sow. A remarkable variety of 

 this species, with three unusually prominent revolving ribs 

 (so much so as to remind one of some of the Australian 

 Trochocochleas), occurred in 70 fathoms, sand, off Moisie 

 village. The type is abundant and large almost everywhere 

 in the St. Lawrence in shallow water. 



Bissoa carinata, Mighels. Frequent, alive, from 96 fathoms 

 in Trinity Bay. 



Bissoa castaneay Moll. With the above, and elsewhere not 

 unfrequent. 



Bissoa scrohiculata^ Moll. Collected in three localities, in 

 from 125 to 250 fathoms, where it is large and fine. It 

 occurs living, but of small size, in Gaspe Bay, at depths of 

 from 20 to 30 fathoms. 



Bissoella ehurnea^ Stimpson. One living and adult example, 

 in 70 fathoms, off Moisie village. 



Lacuna glacialis^ Moller. A living adult specimen of this 

 species was dredged from 96 fathoms in Trinity Bay. The 

 shell is not a true Lacuna^ and belongs, in my judgment, to 

 a new genus. 



Aporrliais occidentalism Beck. A remarkable thin and in- 

 flated variety of this species was taken in 120 fathoms off 

 Bear Head, Anticosti. The type is not uncommon through- 

 out the gulf in from 20 to 50 fathoms.
