Note: Numerous specimens from Misaki and two females from the Nagasaki Prefecture in 

 the Sci. Coll. Mus. They inhabit gastropod-shell-like colonies of Hyrfracliiiia sodalis 

 Stimpson and of TT. spiralis Goto. 



In all the specimens before me, antenna 1 acicles do not quite reach up to the level 

 of the extremity of eycstalks, while the le,;s of the right side extend well beyond the tip 

 of the larger cheliped. In these respects, the specimens may be said to stand not in 

 exact harmony with Stimpson's description an i figure of the species. 



Mupagurus gotoi, n. sp. 



(Textfig. 2). 



Almost hairless throughout entire body. Carapace depressed, 

 broadened posteriorly, strongly calcified in the pear-shaped area in 

 front of cervical groove, but very thin and almost transparent in the 

 branchial region so that most of the gills can be seen through from 

 the dorsal side of carapace. 



Rostrum broadly triangular, pointed at tip, slightly carinated, 

 projecting a very short way beyond the level of the antennal angles 

 of carapace ; the antennal angle tipped with a minute spintile. 



Eycstalks moderately large, overlapping the last joint of anten- 

 nular peduncles just at base, slightly curved outward ; eyes scarcely
