ceedingly numerous; Catapagurus socialis Sm., was found in 
swarms at several spots, and at others the maioid Euprognatha 
rostellifera Stimpson, abounded. 
Of Parapagurus pilosimanus Sm., about 400 examples were 
taken at one station in 312 fathoms, always associated with a 
polyp which builds itself around the crab and absorbs the shell it 
resides in. This species was previously known only from a few 
specimens taken by the Gloucester fishermen in deep water off 
Nova Scotia. 
During 1882 Crustacea were less abundant than in previous 
years, but the large shrimps, Pandalus leptocerus and P. propin- 
guus, occurred, the latter at depths of from 158 to 640 fathoms. 
Among the most interesting species were the large cancroid 
Geryon quinquedens Sm., which was taken in considerable num- 
in from 322 to 452 fath. Lithodes maia abundant at 291 
fath.; the macruran Pentacheles sculptus Sm., of the family Eryon- 
tide, a form known only by six examples; the Crangonids, 
Ceraphilus agassizii Sm., taken in from 291 to 640 fath., and Sa- 
binia princeps Sm., in 374 to 452 fath.; Hippolyte lilljeborgit Dan- 
ielsen, frequent in 144 to 640 fath.; Janira spinosa Harger, in 
640 fath.; Astacila granulata in 291 to 640 fath. ; and Boreomysis 
tridens in 351 fath. Two new species of Galatheidæ, allied to 
unida, were also taken. i: 
he scarcity of many species, such as Catapagurus socialis, 
Pontophilus brevirostris, and a Munida which, though most abun- 
in 1881, was not seen at all in 1882, is accounted for by Pro- 
fessor Verrill by the occurrence of a severe storm which forced 
the belt of cold water outward into the area occupied ordinarily 
by the warmer water, thus lowering the temperature to a degree 
to the more delicate forms. (
