372 Mr. E. J. Miers on Malaysian Crustacea. 



Java (an adult male, in shell of Pyrula) ; Borneo, Bandjer- 

 masin (adult and two young, in shells of Auricula and 

 Purpura) ; Batjan (adult and two smaller females, in shells of 

 Auricula, Pyrazus, and Murex). 



Whether these specimens belong to the C. compressa of 

 Milne-Edwards is difficult to determine from his very short 

 description ; but they appear to be referable to that species as 

 characterized by De Haan, to the C. Olivieri of Owen as 

 described by Dana, and to C. cavipes of Stimpson, although 

 each of the above-cited authors lays especial stress upon dif- 

 ferent characters. Stimpson says that C. cavipes differs from 

 •G. compressa in not having the branchial regions laterally 

 inflated ; but this is a relative distinction, and I have observed 

 a more considerable inflation of the branchial regions in some 

 specimens than in others. The principal characteristics of 

 this species appear to consist in the compressed eyes, which 

 are granulated above, in the larger hand being smooth on 

 the lower part of its outer surface, granulated on the upper 

 part, but without the series of oblique crests of C. rugosa, 

 in the penultimate joint of the left third leg being convex on 

 its outer surface at its upper and distal end, the terminal joint 

 scarcely longer than the preceding, naked, and flattened on 

 its outer surface, with corneous-tipped tubercles only on its 

 upper and inner surface (both terminal and penultimate joint 

 being granulated on their inferior margin) ; the tarsal joint of 

 the third right leg is subcylindrical, and the coxa? of the fifth 

 legs not greatly produced, in the male. 



This would appear to be a very common and widely 

 ranging species. 



It is of interest to note that the Auricula and Pyrazus 

 inhabited by this hermit-crab are brackish-water shells.

A young male inhabiting the shell of a species of Nerita is 

 in the collection from Batjan, which is nearly allied to C. 

 perlata as described by De Haan, and to C. purpurea, Stimp- 

 son. The carapace is very roughly but uniformly granulated 

 above in front of the cervical suture ; the branchial regions, 

 which have the anterior margin nearly straight, are punctu- 

 lated. The larger chelipede is tuberculated on its outer sur- 

 face ; the tubercles white, with dark corneous tips ; no trace 

 of larger tubercles disposed in oblique series. The penulti- 

 mate joint of the third left leg is granulated on its outer and 

 more distinctly on its upper surface, and very distinctly granu- 

 lated on its lower margin. The tarsal joint is somewhat
