BRACHTUEA FEOM TORRES STRAITS. 11- 



raore closely granulated tlian is shown in tlie figure, the granules heing of different sizes,, 

 smooth and rounded on the posterior part of the carapace, and becoming spiniform in 

 front and at the sides. Tlie spinules on the haud are more thickly set and those on the 

 legs are longer than in Miers's figure. 



Localitij. " Torres Straits." 



With the above I may associate provisionally two specimens which I cannot identify 

 with certainty. The smaller (length 5 mm., breadth 7 mm.) resembles somewhat closely 

 the specimens of A. Injstrix, difTeriug chiefly in the Ijlunter armature of the I)ody and 

 legs. The granules of the carapace are less closely packed and are rounded, not spiniform 

 in any part ; on the chelipeds they are conical, and on the legs they have the form of 

 bluntly truncated spines. In the larger specimen (length 9 mm., breadth 12-5 mm.) the 

 granules of the carajmce are still more depressed and smoother, and the tubercles on the 

 limbs are less prominent. These specimens differ from Actica iiodnlosa, Ad. & White, 

 in the much narrower carapace, the breadth-ratio of which is about 1-4 as compared with 

 1-56 in the last-named species. The Chlorodius fracj'ifer of Adams and Wiiite, referred 

 to Actceodes by Miers, is apparently a somewhat similar species, but the carapace is still 

 narrower (breadth-ratio 1'19) than in our specimens and the lobes of the antero-lateral 

 margins are indistinct and spined. I think it not improbable that a larger series would 

 connect these specimens with A. hystrlx and possibly with some of the older species.

A male specimen, 10-5 mm. in length by 15-5 mm. in breadth. The carapace is 

 relatively narrower than in other specimens of this species in the Museum of University 

 College.

Eleven specimens, four males and seven females, showing some variation in thei-elative 

 prominence of the lobules on the carapace and in the acuteness of the antero-lateral 

 teeth. Some of the specimens show very distinctly the spinulation of the upper edge of 

 the merusof the ambulatory legs which De Man finds in the type specimens (Zool. Jahrb. 

 Syst. viii. p. 520).
