PAGURUS SCABRIMANUS. lOl 



half of the convex outer surface spinulous , under half 

 nearly smooth ; upper margin of the mobile finger spinu- 

 lous, outer surface of the fingers and upper half of the 

 outer surface of the hand covered with many long scat- 

 tered hairs , inner convex surface of the hand smooth with 

 some few hairs. — Fingers acuminate with horny, a little 

 spoonlike tips. Upper margins and outer surfaces of the 

 carpopodite and the hand of the right anterior leg armed 

 with many strong spines and more closely provided with 

 long horny hairs than in the left leg. Tarsi of the am- 

 bulatory legs elongate and like the penultimate joints com- 

 pressed; tarsus und penultimate joint of the left ambula- 

 tory leg of the third pair quite resembling Dana's figure , 

 outer surface of the tarsus being flattened and provided 

 with a longitudinal groove, its upper somewhat convex 

 margin, as also the upper margin of the penultimate and 

 the anterior margin of the antepenultimate joint being 

 spinulose ; the two last joints of these ambulatory legs 

 closely covered with many horny long hairs. 



Dana makes no mention of the occurrence of the long 

 hairs on the hands in his Pag. scahrimanus , and the up- 

 per part of the outer surface of the larger hand appears 

 to be less spinulous in this species than in our specimen; 

 the mobile finger of the large hand , very spinulous in 

 the Djeddah specimen, is «hardly spinulous" in the other. 

 The scahrimanus occurs in the Philippine Archipelago , but 

 this cannot cause any difficulties , many other species of 

 Pagurus having also a wide geographical range , as for 

 instance , the Pag. punctulatus that occurs in the Red Sea , 

 the China seas and on the shores of the Sandwich isles. 

 Our species may also be nearly allied to or identical with 

 the Pag. spinimanus M. E. or the scutellatus M. E. , but 

 the description (without figure) of these species by Mr. 

 Milne Edwards (Ann. Scienc. Nat. Ill Série , tome X , pag. 

 61) is too short for us to be able to recognize them. Our 

 specimen is of a uniform light gray or yellowish colour 

 without any spots.
