Similar specimens were taken by the U. S. Fish Commission in 1872, in 

 the Bay of Fundy, at low- water and at the surface ; and in 1877, off Halifax 

 and the Atlantic coast of Nova Scotia. In the Gulf of St. Lawrence this 

 species was collected by the writer, in 1872, at the Magdalen Islands, in a 

 towing net, in floating weed ; and in 1873, by a lowing net off Pictou 

 and in Shediac Bay; at low-water at Poiate du Chene, Shediac Bay; and, by 

 the dredge, in 4i fathoms, on the Egmont Bank, Northumberland Strait. 



Idotea PHOSPiiOREA, Harger. 



"This species is found associated with the last among rocks and sea- weed 

 along the entire coast of New England and extends northward to Halifax, 

 Nova Scotia, and the Gulf of St. Lawrence. It appears to be a more 

 northern species than /. ii'rorata, as it is comparatively rare south of Cape 

 Cod, while it is abundant in Casco Bay, Maine, and in the Bay of Fundy " 

 (Harger). In Canadian waters it has been taken by the U.S. Fish Commis- 

 sion in 1872, in the Baj'of Fundy, at two localities ; and in 1877, off Halifax, 

 Nova Scotia ; also by the writer in 1873, on the Egmont Bank, a small 

 rocky patch to the N.E. of Shediac Bay, in i\ fathoms, with the preceding 

 species. 



loDTEA ROBUSTA, Kroyer. 



From the south shore of L mg Island, northward to Greenland, often taken 

 swimming free or among masses of sea-weed, sometimes in mid-ocean. In 

 Canadian watei'S, so far, it has only been taken off Halifax, at the surface, 

 by the U.S. Fish Commission in 1877. 



Syxidotea nodulosa (Kroyer). 



Idothea nodulosa, Kroj-er (1849). 

 Synidotea nodulosa, Harger (1878). 



Specimens of this species were "dredged off Halifax by the U. S. Fish 

 Commission at several localities in the summer of 1877, in from 16 to 190 

 fathoms on sandy and rocky bottoms, with red alga; at one locality. A speci- 

 men was brought from Georges Banks by Mr. Joseph P. Schemelia, of the 

 schooner Wm. H. Raymond, in the summer of 1879, and Mr. J. F. Whiteaves 

 has sent to the Museum two specimens collected by Mr. G. M. Dawson, in 1 1 1 

 fathoms, Dixon Entrance, north of Queen Charlotte Island, British Columljia." 

 " The range of the sjDecies would therefore be, as at present known, from 

 Georges Banks to Greenland and the Arctic seas, and southward on thePacific 

 coast as far as British Columbia" (Harger). The "several localities" off 

 Halifax, are elsewhere stated to be: olf Halifax, N.S., in 16 fathoms; 120 

 miles .south of Halifax, in 190 fathoms; and Halifax, outer harbour, in 

 18 and 16 fathoms.
