CAPRELLIDAE OF WESTERN NORTH ATL.\NTIC 75 



the terminal articles of pereopods 3 and 4 varied from 1-4, of which 1 

 was sometimes plumose. The number of setae on the inner lobe of the 

 maxilliped varied from 3 to 4. 



Distribution. — Type-locality: St. Croix Kiver, New Brunswick, 

 at a depth of 9-18 m. 



Other records: Several localities in the Bay of Fundy to a depth of 

 91m; Mount Desert Region, Maine. 



New records: 44°00' N., 68°15' W., 101 m; 39°54'30" N., 70°20'00" 

 W., 713 m. 



Remarks. — The 3 males available to me were taken from greater 

 depths than the material which was exammed by Huntsman. I have 

 been unable to examine Huntsman's type material but my specimens 

 agi'ee closely with his description and figures. 



Thus far this species has been collected only in the Gulf of Maine to 

 Cape Cod region.
