No. 2.] AVHITEAVES — ON DEEP-SEA DREDGING. 95 



Yoldla (^PortlandkC) lucida, Loveo. Living iu seven of the 

 localities examined, its range in depth being apparently from 150 

 to 250 fathoms. 



^Yoldla (^Portlandla) frigida Torell. Frequent, living with 

 the preceding. This and the preceding are new to America. 



Dacrydium vitreum, Moll. In 212 fathoms, mud, to the S.S.. 

 E. of the east point of Anticosti, living. 



Cri/ptodon Goiddii, Philippi. Common, living, at all depths;, 

 it ranges from 10 to 250 fathoms. 



Astarte lactea, Brod & Sow, Fine in several localities. Off 

 Sawhill Point in 30 fathoms ; off Moisie village in 70 fathoms ; 

 mouth of St. John's River, Mingan, in 50 fathoms; Gaspe Bay. 

 The young is Astarte Bichai-dsonii, Beeve. 



Astarte. Two species of Astarte, both of the A. sulcata 

 group, were collected in deep water. One, of which two speci- 

 mens only were dredged (off Bear Point, Anticosti, in 1 12 fathoms), 

 I at first thought to bo A. crebricostata ; the other is by far the 

 most abundant mollusk of the greater depths of the northern part 

 of the river and gulf of the St. Lawrence. Mr, Jeffreys says that 

 this latter shell is Astarte sulcata^ var. minor. No specimens that 

 I have seen, from American or European localities, exactly re- 

 semble either of these shells; and in my judgement, both are new 

 and good species. 



TeUina (^Maco?na) inflata, Stimpson, MSS. Perhaps M. fra- 

 gills of Leach. Fine living specimens of a shell which the late 

 lamented Dr. Stimpson gave to the writer some years ago, with 

 the label " Macoma injiata, St. MSS,," were dredged in 70 

 fathoms, sand, off Moisie village, and at various depths iu other 

 localities. 



^Necera arctica, Sars. Several living specimens of this species 

 (the largest of which measures upwards of an inch and a quarter 

 in its greatest breadth) were taken in 125 fathoms, off Cap-Rosier 

 lighthouse ; also in 200 fathoms, mud, Ellis Bay, Anticosti, bearing 

 S^S.W,, 27 miles distant. 



Mecera obesa, ItOYen (=iN. pelhicida , Stimpson). Off Caribou 

 Island, on the north shore of the St. Lawrence, nearly opposite 

 Cape Chatte, living, in 170 fathoms, mnd. I regard both N.^ 

 arctica and JSf. obesa as varieties of the European N. cusjndata, A^. 

 arctica being adults of unusual size, and A^. obesa the young of 

 the same species. In deference to Mr. Jeffreys's greater experience, 

 however, I keep the two forms separate. N. arctica has not pre-- 

 viously been found on the American coast.
