REPORT ON THE BRACHYURA.

Cyrtomaia murrayi, n. sp. (Pl. III. fig. 1). 
The carapace is rather broader than long, convex, with the gastric and cardiac 
regions much elevated, so that the gastric region is situated above rather than behind 
the hepatic regions ; the gastric region is armed with six long spines, of which two are 
placed at some distance behind the eyes, three posterior to them in a transverse series, 
and one at the back of the gastric region ; on its sides are also two or three smaller 
spinules, there are two spines on the cardiac region, three on each hepatic region, and 
three or four on each branchial region, besides some very small spinules ; also two 
spinules on the upper margin of the orbits, and one (median) on the posterior margin 
of the carapace, three or four are placed in an oblique series on the pterygostomian 
region, and two on the sternal surface of the body, at the bases of the first four 
ambulatory legs. The segments of the post-abdomen, also, are spinuliferous, the second 
segment is transverse and very short, but broader than the following segment, the fifth 
and sixth longer than broad, the seventh narrowing to its distal extremity, which is 
subacute. The slender basal joint of the antennae is not much elongated, and bears 
two spinules on its outer surface ; the merus-joint of the outer maxillipedes has two 
longitudinal series of spinules on its outer surface and is denticulated on its inner 
margin, the merus-joint is also spinuliferous and has, in particular, a strong bifid 
spinule at its antero-external angle ; the chelipedes are very slender and about two and 
a half times the length of the body, with the merus-joint longer than palm and fingers 
taken together, and, as well as the wrist and palm, armed with spinules, which are 
generally alternately long and short ; palm about twice as long as the wrist and not 
more dilated than that joint, fingers about half as long as the palm and (as already 
stated) nearly straight, but slightly decussate at the tips. Ambulatory legs extremely 
long and slender, the merus and ischium-joints are armed with spinules, which are 
often alternately longer and shorter ; a stronger spinule exists at the distal ends of the 
merus-joints ; the clactyli of the first and second pairs are very minutely spinuliferous, 
the penultimate joints and dactyli of the fourth and fifth legs are devoid of spines, 
slightly compressed, and fringed with hairs. Colour (in spirit) light brownish-yellow. 
The description and dimensions are taken from the smaller but more perfect 
specimen, the larger having lost all the legs, except a chelipede. 
Two imperfect examples (adult males) were collected near the Ki Islands (Station 
192), in 140 fathoms, lat. 5° 49' 15" S., long. 132° 14' 15" E.
