122 REV. O. P. CAMBRIDGE ON SOME NEW [Jail. 21, 



part being longitudinally wrinkled ; but tbe pattern described from 

 the female is visible on tbe upperside, though less distinctly, owing 

 to the yellow ground-colour of the female being replaced in tbe male 

 by a red-brown similar to that of the cephalothorax; the blatfk patches 

 (in the two males examined) are also of smaller extent, and occupy 

 tbe four corners of the upperside, leaving a strong well-defined and 

 almost regular Greek cross of a red-brown colour. 



Four adult females and two males of this pretty species were con- 

 tained in the Ceylon collection received from Mr. Thwaites in 1871. 



Subfam. Philodromin^e. 

 Nov. gen. Amycle (nom. propr.). 



Cephalothorax short-oval, the hinder extremity the most pointed, 

 very convex above, almost subcorneal, caput and thorax being con- 

 fluent. 



Abdomen elongate, broader behind than in front, and constricted 

 across the middle, mostly on the sides and upperside. 



Eyes eight, unequal in size, occupying a large area rather in front 

 of the apex of caput and thorax, and forming two quadrangular figures, 

 one within the other ; the outer quadrangle greatly the largest, 

 and formed by the four largest eyes, the inner one situated on the 

 fore margin of the outer one. 



Maxilla long, slightly hollow both on the inner and outer margins 

 (looked at from above with the Spider flat on its back), rather 

 rounded and enlarged on the outer extremities, and inclined towards 

 the labium. 



Labium oblong, with the apex somewhat pointed. 



Legs slender, apparently laterigrade, those of the first two pairs 

 longer than those of the third and fourth, relative length 2, 1, 4, 3 ; 

 terminal tarsal claws two. 



Amycle forticeps, sp. n. (PI. XIII. fig. 6.) 



Male adult, length 2\ lines. 



The cephalothorax of this odd and rather Salticiform-looking Spi- 

 der has the appearance (when looked at in profile) of the hinder part 

 having been trimmed off, the thoracic region being greatly curtailed, 

 while the caput is exaggerated ; and the normal grooves and inden- 

 tations are scarcely visible ; the height of the cephalothorax is more 

 than two thirds of that of the length, its colour is orange-yellow ; and 

 there are a tew erect black bristles within the ocular area. 



Tbe eyes are on tubercles of a paler colour than the surrounding 

 surface ; those of the outer (or largest) quadrangle are rather large, 

 and the tubercles on which they are seated are much the strongest. 

 This quadrangle is rather greater in its transverse than in its longi- 

 tudinal diameter, and its fore side is rather shorter than its hinder one; 

 on the whole it is not far short of being a square : the inner qua- 

 drangle (placed within the larger one) is small, and the four eyes 

 forming it are minute ; but its general proportions are not very 

 different from those of the larger one ; its foremost pair of eyes are 

 (when looked at from the front) a little above the straight line of those
