Station 870, 155 fathoms (abundant); 873, 100 fathoms; 878, 142 

 fathoms (very abundant). It was also taken in abundance this season 

 at many stations in shallow water off Ehode Island. 



In the dredgings off Cape Cod, in 1879, this species occurred at a 

 great number of the stations, in 15 to 116 fathoms, and was very often 

 associated with P. Montagui, and at 116 fathoms with P. inopinquus. 

 It was particularly abundant in 25 to 50 fathoms, several quarts of 

 specimens often being taken at one haul of the trawl. In the dredgings 

 previous to 1879 it occurred very much less abundantly, and was care- 

 lessly confounded with P. Montagu^ under which name specimens of P. 

 leptocerus may have occasionally been distributed in the sets of speci- 

 mens made up from the Fish Commission collections and distributed from, 

 the i^ational Museum. In the dredgings of 1877-'78, it occurred sparing- 

 ly, in 22 to 48 fathoms, in Massachusetts Bay ; and in 75 to 90 fathoms, 

 in the Gulf of Maine, off Cape Ann, in considerable abundance and of 

 large size ; in both localities associated with P. Montagu^ and in the 

 Gulf of Maine with P. borealis also. In Casco Bay, in 1873, a few 

 specimens only were taken. Among great numbers of si)eciraeus of P. 

 Montagui from the Bay of Fundy I have not succeeded in finding a 

 single specimen of the new species, although it very likely occurs there. 

 At Halifax, ISTova Scotia, a few specimens only, most of them very 

 small, were taken, and these were from 18 fathoms. In the region of 

 George's Banks, in 1872, it was taken in 30, 45, 50, 60, and 430 fathoms,
