CETTSTACBA OF THE MEEGTJI ARCHIPELAGO. 237 



found iu Elphinstone Island Bay. I hesitate to determine it, 

 because young specimens differ mucli from the adult. It 

 seems, however, to be allied to Diogenes senex, Heller, a species 

 from Sydney, distinguished at first sight from B. avarus by the 

 larger hand being very pilose.

A. Dactylopodites of the legs of the second and third pair 

 distinctly longer than the propodites.

 Pagurus (Clibanarius) infraspinatus, Hilgendorf, Crustaeeen von Ost- 

 Afrika, 1869, p. 97 (footnote). 



Six fine specimens of this common Indian species were 

 collected ; four of them are without definite locality, and inhabit 

 shells of Fyrula, whereas the two others were found in King 

 Island Bay : one of the latter has no shell, and the other much 

 smaller individual inhabits a JBuccinum. 



Dr. Hilgendorf has kindly compared a specimen for me with his 

 types of Clibanarius infraspinatus from Singapore in the Berlin 

 Museum, and communicated me some remarks about this species 

 and C. vulgaris, Dana {= Cancer clibanarius, Herbst). 



According to Dr, Hilgendorf, the latter species, which was 

 adopted by Dana as the type of his genus Clibanarius, and 

 named by him Clibanarius vulgaris, is closely allied to G. infra- 

 spinatus, Hilgendorf, and only differs from it by the arms of 

 the anterior legs not being armed with a spiniform tubercle at 

 the proximal end of the inner margin of the under surface. 

 The large typical specimen of Cancer clibanarius, which Herbst 

 figured (t. ii. pi. xxiii. fig. 1), and which is stiU preserved in the 

 Berlin Museum, had and still has a uniform red colour, but 

 another specimen in Herbst's collection presents the same colora- 

 tion as Clibanarius infraspinatus. When we consider that the 

 Berlin Museum, since the days of Herbst, has not received a 

 single crab agreeing with his types of G. clibanarius, but 

 that numerous specimens identical with C. infraspinatus have 

 been frequently added to the collection of that institution, I 

 think we have some reason to regard the old type of Herbst 

 as a mere variety of G. infraspinatus. I am therefore inclined 

 to unite both species under the name of G. vulgaris, Dana.
