sides. The eje-tubercle, which is situated the length of its 

 diameter behind the front margin of the carapace, bears wart- 

 like protubei'ances in its median line, varying from one only to a 

 row of three or four. The mandibles are short and weak. The 

 palpi rather slight, but tuberculated and strongly bespined. The 

 rear segments and trochanters are strongly bespined and the 

 carapace profusely granulated. 



Algidia cuspidata, sp. n. (PL III. figs. 13 a-e.) 



Colour. Male : carapace dingy yellow, with two dark, broad, 

 longitvidinal stripes, beginning one each side of the eye-tiibercle 

 and reaching to the level of the fourth trochanter, where it 

 turns outwards to the margin. The manidibles and palpi are 

 darker, the latter covered with pale wart-like protuberances and 

 the former with black network pattern. The legs are yellow 

 with dark grey rings ; the under side yellow-grey. The female 

 is paler on the carapace ; the dark strij^es not so conspicuous, but 

 the warty pattern more regular. The legs, mandibles, and palpi 

 about the same as in the male. 



The eye-tubercle is hemispherical ; the median row of warts 

 three or four in the males, fewer in the females. 



The carapace in the male is strongly constricted behind the 

 cephalic part, the sides straighter in the female. On the front 

 margin in the male there are seven long spines in front of the 

 eye-tubercle and three smaller behind each corner. In the female 

 are three formidable spines in the centre, flanked by two small 

 ones, and none at the side. The median area and sides of the 

 carapace are thickly covered with warty pustules, but there are 

 none on the darker stripes. 



On the abdominal portion in the male are four transverse rows 

 of powerful spines, while in the female there are only a few large 

 ones near the centre line, and a fewer number of smaller ones at 

 wide intervals reaching to the sides. 



The trochanters of all the legs and the intervals between are 

 strongly bespined. The legs themselves have small denticu- 

 lations, with a short bristle on each as far as the distal end of the 

 tibial joint. The metatarsal joints smooth, the tarsi with short 

 haii-s. The tarsal claws are weak ; those of iii. and iv. with short 

 side wings springing from about the middle. On the under side 

 the coxte are all bordered with rows of warty prominences, the 

 front margin of coxse i. having a row of sharp pointed black 

 spines. 



The margin of the genital operculum is divided into about 

 ten or eleven distinct scopulations or pustules, each terminated 

 with a bristle. 



The mandibles are short and weak, and covered with short 

 black beady pustules. 



The ^jft^jji are about the length of the carapace in the male,
