in the Gulf of St. Lawrence. 349 



Yoldia (? Portlandid) thraciceformisj Storer. One living speci- 

 men occuiTed in 212 fathoms, S.S.E. of the east point of 

 Anticosti, and a dead, but perfect one, in 125 fathoms, off 

 Cap Rosier. 



Yoldia {Portlandia) lucida^ Loven. Living in seven of the 

 localities examined, its range in depth being apparently from 

 150 to 250 fathoms. 



"^Yoldia [Portlandia) frigida^ Torell. Frequent, living with 

 the preceding. 



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

 of the east point of Anticosti, living. This and the pre- 

 ceding are new to America. 



Cryptodon 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 ; oiFMoisie village in 70 fathoms; 

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

 Bay. The young is Astarte Richardsonii^ Reeve. 



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

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

 specimens only were dredged (off Bear Point, Anticosti, 

 in 112 fathoms), I at first thought to be -4. crebricostata j 

 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 resemble 

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

 and good species. 



Tellina [Macoma) inflata, Stimpson, MSS. Perhaps M.fragilis 

 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 fragilis, St. MSS.," were dredged 

 in 70 fathoms, sand, off Moisie village and at various depths 

 in other localities. 



^Newra arctica, Sars. Several living specimens of this spe- 

 cies (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. 



'^Neo'ra ohesa, Loven ( = N.jJelhicida, Stimpson) . Off Caribou 

 Island, on the north shore of the St. Lawrence, nearly oppo- 

 site Cape Chatte, living, in 170 fathoms, mud. I regard 

 both N. arctica and N. obesa as varieties of the European 

 N. cusjyidata, N. arctica being adults of unusual size, and N. 

 obesa the young of the same species. In deference to Mr.
