Paguristes digitalis Stimpson. 



Paguristes digitalis, Stimpson, Proc. Acad. Nat. Sci. Philad.,

 fig. I. 



Paguristes kagoshimensis, Ortmann, Zool. Jahrb., Syst., VI, 1892, 

 p. 281, pl. xii, fig. 8. 



Note : Common in the neighbourhood of Misiki. According to Ortmann, this species should 

 be very nearly allied to, if not identical with, Paguristes barbatus (Heller). As a point 

 of marked difference between the two, it should be mentioned that, whereas P. barbatus 

 possesses ten gills in all, P. digitalis has thirteen of them. Moreover, in the specimens 

 which I refer to this species the dactylus of crawling legs is distinctly longer than the 

 propndus, instead of the two joints being equally long as given for P. barbatus ; and the 

 abdominal appendages are slightly curved outwards in the distal parts as in P, acantho- 

 merus, not straight as they should be in P. barbatus. 



Paguristes palythophil/us Ortmann. 



Pagttristes palythopldlus, Ortmann, Zool. Jahrb., Syst., vi, 1892, 

 p. 277, pl. xii, fig. 5. 



Note: There is in the Sci. Coll. Mus. a single male specimen from Misaki which I should 

 refer to this species, though differing somewhat from Ortmann's description in two 

 points, viz. (I) in the rostrum being relatively shorter and not reaching to the extremity 

 of ophthalmic scales, and (2) in the dactyli being only slightly — instead of considerably 

 — longer than propodi of ambulatory legs. 



Paguristes seminudus Stimpson. 



Paguristes seminudus, Stimpson, Proc. Acad. Nat. Sci. Philad., 

 1858, p. 247; and Smiths. Misc. Coll. XLIX, 1907, p. 213. 



Note : A male and two females from the Nagasaki Prefecture in Mr. R. Saitô's collection. 

 In the former the eye-stalks are slender ; in the latter which are of a smaller size, they 

 are stouter. The spinules in the antero-lateral regions of carapace are scarcely recogniz- 

 able in the females.
