15”, W. long. 65° 51’ 25’, 810 fathoms ; the two females off the Carolina 
coast, stations 526 and 329, 464 and 603 fath. 
The species is allied to L. maia and L. antarctica in having no scale 
_ and only a single spine at the base of the antenna, and in the general 
form and armament of the carapax and appendages, but differs from 
them both conspicuously in the rostrum, which is rather short and tri- 
spinous, with the lateral spines nearly as long as the rostral spine itself. 
The spines upon the carapax and appendages are more numerous and 
much more acute than in LZ. maia, and the marginal spines of the cara- 
pax are not very much larger than the dorsal. The two adults differ 
remarkably from each other, and from the immature specimens, in 
the number and length of the spines upon the carapax and legs, the 
spines being fewer and very much longer and more slender in the small 
specimens than in the adults, and more slender and more numerous in 
the smaller than in the larger of the two adult specimens. 
Four of the five specimens seen give the following measurements in 
millimeters :

PAGURIDEA. 
Bupagurus pubescens Brandt ex Kroyer. 
This species appears to be restricted to a very narrow region south 
of Cape Cod. It has not been taken in over 65 fathoms off Martha’s 
Vineyard, though common in much deeper water north of Cape Cod. 
None of the specimens seen are large, and all the carcinecia are com- 
posed of Epizoanthus Americanus or entirely overgrown with it.
