BRACHTUEA FEOM TORRES STEAITS. 25 



De Man and Ortmann as synonymous with the present. De Man's description and figure 

 (I. c.) agree closely witli our specimen, save that the orbits are more oblique and the 

 fingers of the chela much longer in the figure. 



Locality. "Torres Straits." 



Distribution. Eed Sea to Sandwich Islands. 



Ceratoplax (?) sp. 



An imperfect dried specimen resembles rather closely in general shape the Ceratopln.r 

 ciliata of Stimpson, as figured by Miers (Chall. Rep., Brachyura, p. 234, pi. xix. fig. 3). 

 It differs, however, in the broader meral and carpal joints of the walking-legs (Miers 

 states that in his specimen the legs " are i-ather more slender than in the description of 

 Dr. Stimpson ") and in the rather stouter fingers of the chelipeds. It differs, moreover, 

 not only from Miers's figure, but also from the generic diagnosis in the fact that the 

 antero-external angle of the merus of the third maxillipeds is roimded oil' and not 

 distinctly produced. 



Locality. " Torres Straits." 



Calappa hepatic a (L.). 



Calappa hepatica (L.), Alcock, .Tonrii. Asiatic Soc. Bengal, Ixv. (2) p. 142 (1896). 

 Three female specimens, the carapace of the largest measuring 40 mm. in length by 

 60 mm. in breadth. 



Locality. " Miu-ray Island." 



CRTPTOCNEMrs Haddoni, n. sp. (Plate 1. figs. 4-8.) 



Description. The margins of the lateral wings of the carapace are convex, presenting no 

 salient lateral angle such as is present in C. pentagonus, Stps., and passing, with scarcely an 

 indication of a poster o -lateral angle, into the posterior margin, where the curve meets its 

 fellow in the middle line in a slight re-entrant angle. The lateral margin is continued on 

 to the dorsal surface of the carapace beliind the hepatic region on either side as a faintly 

 marked ridge which soon dies out. The front is obtusely triangular and slightly reflexed, 

 the straight line of each side being continued beyond the orbit to the prominent hepatic 

 angle. On the flat dorsal surface a low longitudinal keel runs from the tip of the 

 rostrum to near the posterior edge of the carapace, being most prominent on the cardiac 

 region, and the branchial regions are very slightly inflated. The surface of the carapace 

 is perfectly smooth ; the posterior and lateral margins, as well as the faint ridges on the 

 hepatic regions, are microscopically beaded. The antennular fossse are transverse. The 

 third maxillipeds have the merus equal in length to the ischium, acutely triangular and 

 projecting well beyond the margin of the buccal area, though not so far as to be visible 

 from above. The exopod is equal in breadth to the ischium ; its outer edge is convex, 

 the tip truncate and very slightly concave. The chelipeds have the merus trigonous, 

 with two minutely granular lines on its lower margin ; the carpus has a slight keel 

 exteriorly ; the hand is compressed, the edges acute, the palm being one and a half times
