NOTE ON SCYLLARUS SCULPTUS, LATR. — -WHITELEGGE. 161 



about eighteen denticles, including the larger ones situated at the 

 inner and outer angles. Second joint twice as broad as long ; the 

 superior distal margin bears five spines ; of these, two are situated 

 on the outer fourth, one about the middle and two on a produced 

 lobe, which projects in front of the basal joint of the first antennye 

 and partly conceals the lower third of the second joint. 



Third joint greatly expanded, somewhat cordiform in outline ; 

 the outer margin is neatly curved, and bears six teeth, each of 

 which is minutely denticulated. The distal margin is oblique, and 

 has four or five large teeth ; the inner border is tridentate, the 

 denticules occur on a projecting lobe similar to, but larger, than 

 that on the inner angle of the preceding joint. 



Fourth joint as broad as long, the inner border with three spines 

 and the distal margin with two or more ; the outer distal angle is 

 produced on the lower surface, but not on the upper. 



Fifth joint nearly one-fourth broader than long • its outline is 

 semi-elliptical ; the margin is shortly ciliate, the inner third is 

 acutely dentate, the rest crenate, the surfaces are minutely hairy 

 punctate ; the upper surfaces of all the preceding joints are more 

 or less scaly or tuberculate. 



First pair of legs stout ; the inferior surfaces of the first three 

 joints are beset with elevated tubercles, with dark brown tips ; the 

 merus is somewhat compressed, the inner surface is smooth and 

 adapted to the carapace, the outer is slightly depressed longitudin- 

 ally ; near the upper border the latter is subcarinate, smooth, and 

 shortly setose ; the inner lower border is similar to the upper, but 

 is less elevated and only half its length ; the outer aspect of the 

 lower border is marked by a series of ten subspiniform scales ; 

 the distal margin has four or five obscure spines. Carpus half as 

 long as the merus, with a strongly marked groove on the outer 

 surface near the rounded upper border. 



Propodus tapering, its greatest depth equal to half the length, 

 its diameter equalling the depth at the distal extremity, the upper 

 and lower borders are rounded. Tarsus curved, as long as its 

 supporting joint, upper surface somewhat flattened, internal aspect 

 grooved, the lower with two tufts of setee near the base ; the 

 distal half is horny, the corneus and calcareous portions overlap 

 at their junction, the latter at the sides and the former above 

 and below. 



Second pair of legs the longest, their length without the tarsus 

 equal to the first and also to the third ; fourth and fifth shorter, 

 the latter nearly equal to the first without the tarsus. 



The merus joint of the second pair is one-fourth longer than 

 that of the first and of the fourth, about one-eighth longer than 

 the third, and nearly twice the length of that of the fifth ; it
