The specimens that I have had the opportunity of examining are 

 apparently all females, and the dorsal process of the fourth pleon 

 segment is just as shown by Sars for the female of H. tubicola. The 

 specific name spinosa is given in reference to the rows of strong spines 

 on the rami of the second uropods. Stebbing^ figures the second 

 uropod of H. laevis as having a row of spines on the outer ramus, but 

 those of the inner ramus are not nearly so numerous or conspicuous 

 as in the present species.

Station 2497 steamer Albatross, east of Nova Scotia, 45° 04' 00" N., 

 69° 36' 45" W., July 6, 1885, 57 fathoms, yellow sand, broken shells, 

 hard; 3 specimens. 



Station 2499 steamer Albatross, southeast of Nova Scotia, 44° 46' 

 30" N., 59° 55' 45" W., July 6, 1885, 130 fathoms, black mud; 4 

 specimens. 



This species was described by Doctor Stephensen from a single 

 specimen taken off the western coast of Greenland by the Ingolf 

 Expedition. His specimen measured 4.5 mm., while the present ones 

 are from 3 to 4 mm. ; they appear, however, to agree very well with 

 the figures he has given.
