33. Chelifee celereimus, sp. n. (Plate XXX. figs. 23 a-c, e ; Plate XXXI. 

 fig. 23^.) 



Cephalotliorax. — No ocular spots were observed. The cephalothorax, which is 

 distinctly longer than wide, has a median fairly prominent transverse groove, which 

 is slightly curved backwards in the middle ; there is no posterior groove. The 

 integument is minutely not very distinctly granular and the short hairs are slightly 

 obtuse. 



Abdomen. — The fairly long and slender abdomen has all the tergites, with the 

 exception of the first and part of the eleventh, divided longitudinally. The tergites 

 have smooth sclerites, and from 14-16 long, pointed, and terminally dentated hairs 

 along the hindmost margin, in addition to four hairs in front of the row ; these 

 hairs increase in length from the base to the end of the abdomen, and from the 

 middle towards the side in each tergite. The eleventh tergite and the corresponding 

 sternite have each two pairs of " tactile " hairs. 



Antennae. — The galea, which extends somewhat beyond the terminal hair, has in 

 the distal half two diverging branches, bearing respectively one and three branches 

 (somewhat similar to Balzan's figure la (lo)). 



Pal^js (PI. XXX. figs. 23 «-c). — The maocillw are almost smooth beneath; the 

 palps are minutely and very distinctly granulated, the inner surface having the 

 granulations most pronounced, the lower surface being almost smooth. The hairs 

 are fairly long or long, are provided with a few teeth, and are scarcely pointed on the 

 proximal joints, but distinctly pointed and almost simple or completely so on the 

 distal joints. The trochanter, which is 1'5 as long as wide, is very slightly convex 

 anteriorly ; posteriorly it is slightly produced, and dorsal! y it is prolonged into a 

 rounded, rather low protuberance. The femur has a short well-defined stalk, beyond 

 which it tapers distinctly towards the end. It is about 2'2 as long as wide ; the 

 anterior outline is slightly convex and then concave, while the posterior is very 

 abruptly convex beyond the stalk, straight in the middle, and then terminally a trifle 

 convex. The tibia, which has a moderately long and well-marked stalk, is a little 

 longer and wider than the femur, and is almost 2-2 as long as wide ; the anterior 

 outline is moderately convex with a scarcely marked terminal concavity, while the 

 posterior, beyond the fairly big condylus and small but distinct basal elevation, is first 

 almost straight and then slightly convex. The chela, which is three times as long as 

 wide, is scarcely broader than the trochanter is long ; the hand, which is about as 

 long as the tibia, but 1"3 wider, is 1'6 as long as wide, scarcely deeper than wide, and 

 I'l as long as the fingers, which are much longer than hand is deep and scarcely 

 gape when closed ; the lateral outlines are moderately convex, while the dorsal and 

 ventral are only slightly so. The fingers each bear anteriorly a single accessory tooth, 

 while posteriorly the movable finger has two and the immovable finger three teeth 

 anteriorly. Eight " spots " are found in the basal half of the immovable finger,
