8 Fulton and Grant : 



posterior and are divided into four obscure lobes of which the last 

 pair are the smallest. Front considerably depressed and divided 

 by an obscure median sulcation. Orbits visible from above, 

 small, their upper margin with two small fissures. The basal 

 antennal joint nearly reaches the frontal process, the fiagellum 

 occupying the inner orbital hiatus, epistome well defined, 

 transverse. 



Chelipedes sub-equal, smooth, and polished on under surface. 



The merus trigonus, very short, without hairs, smooth and 

 polished, its upper margin somewhat reflexed, sharply cristate. 



The carpus clothed on the outer surface with a dense tomentum 

 and fringed with long hairs, the surface granulate. 



The propodus nearly as deep as long, similarly clothed except 

 a large triangular space on the outer surface which is porcelain- 

 white, smooth, polished, and finely punctate. 



Tlie fingers short and stout, pointed, coarsely toothed showing 

 a considerable hiatus when closed, their distal half being black- 

 brown in colour. 



Ambulatory legs compressed but not cristate, all the joints 

 fringed with long hairs, the three distal joints of the first three 

 pairs being tomentose, the other joints being clean and polished 

 on their outer surface. The last pair have all the joints fringed 

 and tomentose. 



Post-abdomen of the male and female with seven segments, 

 the last two entirely filling the space between the ba.ses of the 

 last pair of ambulatory legs. 



This species is not uncommon under stones between tide lines 

 in Port Phillip and Western Port, though it may easily be over- 

 looked as it lies very close, its colour and clothing protecting it.

HaswelP has a note identifying a specimen taken at Port 

 Molle, Queensland, as Puluranus fimbriatus, Milne-Edwards,^ in 

 which Miers^ agrees. The latter author fully described it, and 

 forms a new genus (Cryptocaeloma) for its reception.
