Ciiii/roN. — Crustacea of lltr Kennadtc. Ulanih. 561 



species are recorded from South Africa, the Indian Ocean, New Guinea, 

 Tasmania. &c., and a careful review of tlie genus is desirable.

Several specimens washed up on Denham Bay Beach, Sundav Island, 

 in October, 1908. 



The species is pelagic in habit, and is very widely distributed in tropical 

 and temperate seas. Specimens from New Zealand are in the British 

 Museum collections. 



Ocypoda kuhlii De Haan. 



Ocypoda kuhlii Miers, Ann. Mag. Nat. Hist., ser. 5, 10, p. 384, 1882 ; Miers, 

 Collection H.M.S. " Alert," p. 237, 1884. 



Several specimens from Sunday Island seem to belong to this species as 

 described by Miers. The carapace is evenly granulated throughout, as in 

 some of the specimens examined by Miers. Specimens were obtained at 

 Thursday Island during the cruise of the " Alert," and the species is known 

 from other parts of Australia, and is also widely distributed elsewhere.

Several female specimens from Meyer Island " in brain-coral, 2 fathoms " ; 

 also two or three small male specimens among other Crustacea from Coi-al 

 Island. 



The males are much smaller than the females, and are less modified 

 from the normal Brachyuran type — just as is the case in C. dimovphus 

 Henderson.* 



Of the Meyer Island specimens Mr. Oliver says, " Lives in a perfectly 

 <-ircular hole bored in living brain-coral." 



In general appearance and mode of life these specimens evidently closely 

 resemble this species, but I have no means of consulting Heller's description. 



Mr. McCulloch has kindly compared a specimen from the Kermadecs 

 with those collected ofi the coast of Queensland by himself and referred 

 to this species, and finds that they are identical. He states, however, that 

 he is doubtful if these specimens should really be referred to C. coralliodytes, 

 as they appear to differ in certain points, and he suggests that they pro- 

 bably form a new species, distinct also from C. dimovphus Henderson, from 

 the Andaman Island. I postpone consideration of this question till I can 

 •consult Heller's description of C. coralliodytes.
