Xymphon hirtum, var. obtusidigitum (Miers), PL III. fig. 3. 



Among the specimens from Franklin Pierce Bay is a 

 single example, which differs from the males of the foregoing 

 variety only in the legs being cylindrical, not dilated and 

 compressed, and in the form of the chelae of the mandibles. 

 These have the fingers arcuate, meeting only at the tips, 

 which terminate in small knobs. The chelae are slender, 

 not globose, as in the form figured by Bell, in Belcher, 

 ' Last of the Arctic Voyages,' p. 409, pi. xxxv. fig. 4, under 

 the name of X. robustum, and that recently described by 

 Heller as X. Mans (' Sitz. cler k.-k. Akad. ; ' Wien., ' Naturw.' 

 lxxi. p. 610, 1875), in which species the fingers although 

 arcuate are represented as acute. 



Xymphon Stromii (Kroyer).

 three specimens, and at lat. 81° 56', one specimen; Cape 

 Frazer, at a depth of 80 fathoms, bottom hard, one adult 

 and three young specimens.
