JAPANESE HERMIT-CRABS. 



381 



reaching to the end of the proximal third of the last joint of antennal 

 peduncle. 



Chelipeds and ambulatory legs thickly beset with thorn-like spines 

 and tufts of bristles, especially in the last three joints and on exten- 

 sor surfaces ; with stronger tooth-like spines along the crest-like inner 

 border of merus and moderately strong spines along the upper inner 

 border of carpus and of the palm of left cheliped. 



Left cheliped much larger than the right, its length equal to 

 about seven-eighths that of carapace ; lower border of palm with a 

 well-defined series of tubercles. 



Ambulatory legs compressed, those of the left side reaching 

 beyond cheliped of the same side ; those of the right side even longer. 



Abdominal appendages well-developed in the female. Abdominal 

 spur present. 



Colour. — In spirit yellowish but reddish towards tip of legs ; 

 numerous minute spots of a reddish colour scattered on carapace, 

 legs, and abdominal terga ; eyestalks with a broad purplish cross- 

 band ; bristles yellowish. Formalin specimens show punctulation of a 

 darker colour ; bristles reddish or brownish red and mostly yellowish 

 distally. 



Note : The type specimen is a female from Kome-no-tsu, Prov. Satsuma. It is preserved 

 in the Sci. Coll. Mus. Carapace length 32 mm. Further, there are in the same 

 collection two males, one from Prov. Kii and the other from the Nagasaki Prefecture ; 

 a female from Tempôzan, Prov. Satsuma, in the collection of the Kagoshima II. Middle 

 School ; a male in Mr. R. Saitô's collection ; and finally, a male in the collection of the 

 Tokyo Higher Normal School. 



This species is closely allied to Pagurus megislos (Herbst), but differs from it in 

 the shorter eyestalks, in the punctulation being of a reddish instead of a whitish colour, 

 and in the c mvergently U-shaped suture-line in front of cervical groove. This species 

 is also very near to P. diogenes Fabricius but is distinguishable by the left chela being 

 not so much shortened as in the latter species.
