Carpus longer than the propodus, al)()ut e(|ual to tlu; tarsus ; 

 that of the first leg has a minute spiiiule at its outer distal apex. 



Propodus slightly eoni pressed, deepest about the middle. 



Tarsus rounded, tapering gradually to the short l)ut little curved 

 horny claw. 



Post-abdomen seven-jointed in Ijoth male and female, closely 

 •covered with hairs, similar to but shorter than those on the cara- 

 pace ; the female has a marginal fringe of long seti>j. 



The spines and granules are generally of a bright red colour.

Thirty-two examples were obtained. The range extends from 

 Cape Three Points to Wollongong, and the depth 23 to 71 fathoms. 



Mr. E. J. Miers, in his remarks on Pilumnns rufo-punctat.us, 

 Stimp., states* that Stimpson's species " possibly is itself to be 

 identified with P. tomentosus, Milne Edwards." It is again 

 referred to in the Challenger Report,! and the opinion expressed 

 that F. 7-iifo-p>inctatus, Stimp., '' may be the true Filumnus 

 tomentosus, Latreille." 



It seems quite possible that the original description given 

 by Latreille was ignored in dealing with this species. Had it 

 been consulted I feel sure that the conclusion arrived at would 

 have been different. The brief diagnosis of Latreille agrees with 

 examples of those here regarded as P. tomentosits, and further, it 

 does not accord with specimens of P. rufo-punctatus, Stimpson. 

 There are several characters exhibited by the latter sj)ecies which 

 have not been noted. The carpal and propodal joints of the ambu- 

 latory legs are armed posteriorly and superiorly with numerous 

 subspiniform granules, similar to but smaller than those on the 

 carpal joints of the chelipedes. The hairs on the carapace and 

 limbs are very short, and measure from 0-3 to 0-4 mm. in length; 

 each hair bears a subterminal cluster of branchlets ; the latter are 

 confined to a space about 06 mm. in length. The branchlets 

 ai'e generally covered with flocculent matter, and the hairs appear 

 to be capitate when seen under a low magnifying power. 



The hairs on the carapace of Pilamnus toinp.ntosus measure 0*5 

 to 0*8 mm. in length, and they are quite smooth and unbranched.
