REPORT ON THE ANOMURA. 5 



segments have a dense matting of hairs. Tlie male sexual organs are well developed, 

 the first pair robust, the second ending in a long and delicate horny filament; in addition 

 a membranous tubular process (length 5 '3 mm.) arises from the coxa of each fourth 

 ambulatory limb. These processes are directed forwards, and lie to the outside of the 

 first pair of genital appendages ; they gradually narrow towards the free end. 



Breadth of carapace 27'5 mm., length of carapace 25 mm., of chelipede 28 mm., of 

 third ambulatory leg 16 mm. 



The fringe of hairs on the carapace, and the position of the cervical groove, are the 

 chief characteristics of this species. Dromidia excavata, Stimpson (from Port Jackson), 

 has the subhepatic regions deeply concave, is a much smaller species, and various other 

 points of difference exist. Dromia glohosa, Lamarck, possesses a tooth on the lateral 

 border in front of the cervical groove, and a prominent tooth divides each antero-lateral 

 border into two parts. 



Habitat— Station 162, off" East Moncoeur Island, Bass Strait; depth, 38 fathoms; 

 bottom, sand and shells. 



The single specimen taken is an adult male, found living with and firmly attached to 

 a large Simple Ascidian.

Carapace convex, pubescent, scarcely pilose. Palate furnished with a slight elevation 

 on each side. The sternal sulci in the female remote, terminating in tubercles, produced 

 as far as the segment bearing the second pair of legs. Legs nodose, otherwise similar to 

 * those of Dromia. Species of small size. 



The members of this genus are apparently confined to the Indo-Pacific region. They 

 occur between tide-marks and in shallow water ; some, however, including the best known 

 species — Cryptodromia lateralis — appear to venture occasionally into greater depths.
