ART. 22 STEGOCEPHALID AND AMPELISCID AMPHIPODS SHOEMAKER H 



Ampelisca spinipes is a very abundant species in the vicinity of 

 Woods Hole, Mass., but heretofore it has not been recorded from 

 Nova Scotia.

Station 2481 steamer Albatross, east of Nova Scotia, 44° 07' 30" N., 

 57° 16' 45" W., July 5, 1885, 116 fathoms; 1 specimen. 



This species was described by Sars from the western coast of Nor- 

 way. Chevreux recorded it off Cape Finisterre, and Stephensen has 

 recorded it from several localities off the western coast of Greenland. 

 The present record is the first for the eastern coast of North America. 

 Sars gives 8 mm. as the lengtli of the female, and Stephensen's speci- 

 mens measured between 5 and 7 mm. The present specimen is about 

 4 mm. in length.

 57° 16' 45" W., July 5, 1885, 116 fathoms; 1 specimen. 



Several specimens of this species were taken by the Ingolf Expe- 

 dition off the western coast of Greenland, but it has not heretofore 

 been recorded directly from the waters of the eastern coast of North 

 America. The present specimen measures 7 mm. in length. 



? AMPELISCA TYPICA (Bate)

 1891. Ampelisca typica G. O. Sars, Crustacea of Norway, vol. 1, p. 165, pi. 57. 



Ampelisca typica has not until now been recorded from the West- 

 ern Hemisphere. Sars gives 10 mm. for the length of this species; 

 the present specimen, however, measures only about 5 mm. and is 

 presumably quite immature.
