CAPRELLIDAE OF WESTERN NORTH ATLANTIC 33 



Remarks. — The appendages of C. linearis are quite similar to 

 those of C. septcntrionalis and are discussed under the latter species. 



C. linearis does not appear to be specific in its habitat, having been 

 collected from brown, green, and red algae, sea grass, sponges, hydroids, 

 alcyonarians, and tunicates. Ohlin (1895a) reported it from an Asterias 

 collected ofT Newfoundland. This report may refer to C. unica since 

 the body form and most of the appendages of these species are quite 

 similar and C. unica has been collected off Newfoundland. Mayer 

 (1903) also reported C. linearis from an asteroid, Solaster, which was 

 collected off Scotland. 



C. linearis has been taken from the surface to a depth of sev^eral 

 hundred meters.

 Caprella longimana.— Mayer, 1882, p. 66; 1890, p. 73. 



Remarks. — A caprelhd from Grand Manan was described by 

 Stimpson as 



Body with a few spines along the back of each segment. Superior antennae rather 

 stout and twice as long as the inferior ones, which are very slender. Hands very 

 long and rather broad, with two or three teeth along the inner edge; the arms to 

 which they belong are placed on the thickened posterior part of the second seg- 

 ment. Color light-yellowish brown. Eyes red. Length about three-fourths of an 

 inch. 



From this description it is impossible to tell to which species Stimpson 

 is referring. It might be C. septentrionaUs because of the mention of 

 a few dorsal spines, but several other species bear spines.
