The female is slightly smaller. 



There is a note by Surgeon-Captain Anderson, as to the colour of 

 the species during life, preserved in the bottle which contains the broken 

 specimen. " Legs crimson dotted with yellowish white, under surface 

 of the joints white. Carapace brownish pink. Lived in the accom- 

 panying Rostellaria." 



The species differs from all others so far allotted to its genus, in 

 the form of its non-operculiform hand.

The larger specimen is about 30 mm. long and inhabited the shell 

 of a Harpa. Its extended or unrolled copulatory organ measures 20 

 mm. in length. The species is devoid of any bright colouration and a 

 special feature is the large size of its eyes. The dactyli and propodi 

 of the ambulatory (or probably swimming) legs, are closely fringed with 

 hairs. All the specimens I have met with at Madras — ^where the species 

 is common — occurred in light shells, such as could be easily carried by a 

 swimming animal. A similar selection of the shell in order probably to 

 suit the habits of the inmate, is seen in the genus Clihanarius, the 

 members of which on the Madras coast at least, almost invariably 

 select heavy shells, and are generally found in exposed and often 

 surf beaten situations. 



The present species has been recorded from the seas of Japan, 

 China, Admiralty Is., Torres Strait, Malay Archipelago, and the Bay of 

 Bengal (Madras and Gulf of Martaban). It is a shallow-water form.
