220 PERCY SLADEN TRUST EXPEDITION 



large V-notch and from the acute outer lobes by rectangular sinuses. Two closed fissures 

 above the orbit, none below. 



Chelipeds and legs long, hairy and granulous ; the granules save on the wrist are 

 more scanty than on the carapace. Wrist divided into 3 areas. On the hand the 

 granules are somewhat large and arranged mainly in lines, especially on the middle third ; 

 on the lower third the granules become squamiform and the hairs are short. Fingers very 

 broad, smooth and shining, brown except for the white tips, the brown running back a 

 little on the palm, especially in the male ; tips acute when crossed, leaving a minute gape 

 at base of fingers ; fingers finely dentate in the proximal part of their sharp cutting edges, 

 with a large truncate tooth at the basal third of the immovable finger ; proximal half of 

 upper surface of dactylus granulous and hairy ; immovable finger with 2 longitudinal 

 grooves ; the lower one on the proximal half only, the upper one at the level of the 

 truncate tooth. The carpal joints of the legs have a deep groove on the outer surface. 



Near A. ruppellii, but distinguished by its longer antero-lateral margin, finer areola- 

 tion of carapace, broad, flat fingers.

 here. 



Type $, C. 1. 6-5 mm., C. b. 9"5 mm. 



Of the form of A. ruppellii ; lobules of carapace low, covered with a short fur which 

 partially obscures the granules ; a few scattered, longer hairs. Mesogastric region with a 

 transverse lobule posteriorly, remainder showing a tendency to divide in three. Proto- 

 gastric region divided longitudinally, but not clearly so, the outer portion longer and 

 wider than the inner ; in front of the outer portion there is a tiny islet of 2 or 3 granules. 

 2 F, 1 M, 1 L, 2 L, 3 L, 4 L, 5 L and 6 L are distinct ; 5 L is little larger than 6 L, and 

 has an emargination in its anterior border. Posteriorly the areolation is more obscure. 

 Of the 4 lateral lobes the first is fused with the orbital angle and is inconspicuous, the rest 

 are prominent and bluntly dentiform. Two supra-orbital fissures obscure, suborbital one 

 V-shaped. Frontal lobes obliquely truncate, separated from each other by a large 

 V-notch and from the orbital angle by the downward prolongation which joins the inner 

 angle of the basal antenna! joint. 



Wrists nodulous, hands scarcely so. Chelipeds and legs covered with felt like the 

 carapace but long hairs more numerous. Fingers long, pointed, meeting along their 

 dentate (4 or 5 teeth) edges, light brown, this colour spreading in the $ from the 

 immovable finger over a great part of the palm. Carpal joints of legs grooved. Abdomen 

 of $ unusually slender. 



Can be told at once from A. ruppellii by the lack of many long hairs on the carapace, 

 by the truncate lobes of the front and the slender fingers which are a light brown, whence 

 the specific name.
