Distribution : from Mozambique eastwards, by way of the islands of the 

 Indian Ocean, South India, and the Malay Peninsula and islands, to New 

 Zealand and Japan, and thence through Oceania as far as the Paumotu 

 Archipelago (about i45°W.)' Closely related species occur at Panama. 



2. Aniculus tenebrarum, n. sp. Plate VII., fig. 5. 



Only the wrist and hands and the three terminal joints of the legs are 

 setose. 



Greatest breadth of the carapace about two-thirds its length in the 

 middle line. Rostrum broad, inconspicuous, not surpassing the antennal 

 angles of the carapace. 



Eyestalks slender, much longer than the anterior border of the carapace, 

 and than the antennular peduncles ; eyes small ; ophthalmic scales spiniform, 

 approximated 



The antennal acicle, which is tipped with two or three long setse. 

 considerably overlaps the base of the terminal joint of the peduncle : the 

 flagellum is about as long as the carapace. 



Chelipeds equal, or the left a little the larger, quite similar, about ij 

 times the length of the carapace, with long stiff setae (not nearly so numer- 

 ous as in A. aniculus) on the wrist and hands : merus longer than high, its 

 inner lower border entire ; the free edges of the scutes of the wrist and hand 

 are finely and evenly crenulate in more or less of their extent : fingers short 

 and broad, with hoof-like tips. 



The 2nd pair of legs are about a dactylus-length, the 3rd pair about 

 half a dactylus-length, longer than the chelipeds, their three terminal joints 

 carry long stiff setae, which are most numerous on the dactylus. In both 

 pairs the dactylus is about the same length as the propodite. 



In the female the 4th abdominal appendage is as large as any of the 

 others, all having both rami very well developed. 



Colours in spirit : anterior half of carapace pink, eyestalks red, chelipeds 

 and legs cross-striped light and darker red alternately, the tips of the four 

 terminal joints of the legs white, finger-tips black, claws of dactyli dark 

 brown. 



Length of carapace not quite 10 millim.

The chief difference between this little species and A. aniculus is that 

 it is not nearly so shaggy, and that it has much longer eyestalks. It inhabits 

 shells of Tritonidea delicata and of Rana.
