210 COLLECTIONS FROM MELANESIA. 



sures 5 lines (10| millim.) in length, and about 8| lines (18 millim.) 

 in breadth. 



In two of these specimens the coloration is reddish brown, with 

 the very short pubescence of a brownish hue ; the three others (103) 

 are much paler, and the pubescence is of a light hue. 



These specimens agree with Dana's description and figures in 

 most particulars, and especially in the very considerable transverse 

 width of the carapace, very concave postero-lateral margins, and 

 very short pubescence of the carapace, wherein they differ from 

 most other species of Actcea : the lobes of the antero-lateral margins 

 of the carapace are, however, very indistinct and are themselves 

 interrupted ; and the areolae of the upper surface appear to be much 

 more strongly defined and separated by deeper furrows than in 

 Dana's figure*. His specimens were from the Sooloo Sea or lialabac 

 Straits. 



Actcea consobrina of Alphonse Milne-Edwards f is a closely allied 

 species from Upolu, which, as far as can be learned from the very 

 brief diagnosis, is only distinguished by the lighter coloration and 

 4-lobed antero-lateral margins. It may not be distinct from 

 A. areolata, or, if distinct, perhaps our specimens should be re- 

 ferred to it. 



41. Banareia inconspicua. (Plate XIX. fig. C.) 



Carapace transverse, moderately convex, everywhere clothed 

 with rather short hairs, beneath which the surface is granulated ; 

 similar hairs cover the upper surface of the legs ; the carapace is 

 not lobulated, nor are the interregional sutures visible : the front is 

 4-lobed, the lobes small, rounded, and equidistant. The antero- 

 lateral margins are longer than the postero-lateral, unevenly gra- 

 nulated, with very obscure traces of division into teeth or lobes ; the 

 postero-lateral margins are strongly concave. The epistoma is 

 almost linear-transverse ; the anterior margin of the buccal cavity 

 projects, and is divided by two very distinct fissures. The post- 

 abdomen presents nothing remarkable. The antennules are ob- 

 liquely folded ; the antennae have a rather stout basal joint, which 

 reaches to the infero-lateral angle of the front, and a rather lonf 

 •flagellum. The ischium -joint of the outer maxillipedes is but little 

 longer than the merus, which is nearly quadrate. The chelipedes 

 are nearly smooth and unarmed, without spines or tubercles ; the 

 merus or arm is trigonous, its upper and lower margins fringed wi'h 

 hairs ; the wrist is clothed with hair on its upper and outer surface 

 the angle on its inner surface prominent, but without a tooth or 

 spine ; palm also hairy above and on the upper part of its outer sur- 

 face, naked on the lower part, where it is punctulated, and granu- 

 lated on its lower margin ; fingers nearly as long as the palm, naked 

 (except at the base of the upper margin of the mobile finder or
