Gulf of St. Lawrence, twenty-eight miles E.N.E. of Cape Gaspe, in 110 

 fathoms; and twenty-five miles E. by N. of Cape Gaspe, in 210 fathoms; several 

 specimens from each of these localities, dredged by the writer in 1873. 



PSEUDOMMA TRUNCATUM, S. I. Smith. 



1379. Trans. Conn. Acad. Arts and Sc, vol. v., p. 99. 



Gulf of St. Lawrence, about half-way between the Bradelle Bank and 

 Miscou Island, in 45 fathoms, one male ; also a little to the north of the 

 Baie des Chaleurs, between Grand Pabou and Cap d'Espoir, in 50 and 70

 dredged by the writer in 1873. Two young males and a young female of 

 this species have since been dredged by the U. S. Fish Commission in 

 Massachusetts Bay, off Salem, in 33 fathoms (S. I. Smith).

"Bay of Fuiidy, 1864, 1868, 1870, 1872, 1876 : in great abundance at the 

 surface, and often brought up in the dredge. Off Cape Sable, Nova Scotia, 

 59, 88 and 115 fathom^, sand, gravel and stones, sandy mud, sand and 

 gravel, 1887" (S. I. Smith, 1879 ; Trans. Conn. Acad. Sc. and Arts, vol. v., 

 p. 89). Gulf of St. Lawrence, 210 fathoms, mud, S. of the S.W. Point of 

 Anticosti, dredged by the writer in 1873. 



" Since this, as well as the next species, is essentially pelagic, swimming 

 in vast numbers at the surface, and doubtless at great depths as well, it is 

 of course somewhat uncertain whether the specimens taken in the dredge 

 really come from the bottom or from some point between that and the sur- 

 face. It was found in the stomachs of the hake taken in the Bay of Fundy, 

 in 1872, however, which is very good evidence that it lives at the bottom 

 for a part of the time. 



" In the Bay of Fundy it occurs at the surface in vast swarms, filling the 

 -w - t«r for miles, and is usually accompanied by schools of mackerel, young
