CHELIFERID^ AND GARYPID^ IN THE BRITISH 3IUSEUM. 63 



in the depth of the trochanteral tubercles as well as in the length and 

 slenderness of the tibial stalks, which have the basal elevation more or less 

 pronoanced (cf. figs. 15 & 16). To Cli. elongatus, Ellingsen, it shows a 

 remarkable similarity, but as minor differences are nevertheless observed in 

 the shape of body and palps, and as the localities are so apart, I think that 

 the two species must be maintained (cf. 19).

? . Indistinct ocular spots. Cephalothorax smooth, without transverse stripes. 

 The long and slender abdomen with six fairly long and pointed hairs in 

 front of row. The palps slightly granular anteriorly, with fairly long 

 pointed hairs. Trochanter bigibbose, with dorsal tubercle fairly deep 

 and somewhat conical ; femur, which is 2'2 as long as wide, is attenuated 

 towards the end and posteriorly beyond stalk abruptly convex ; tibia, 

 which has a moderately long and well-marked stalk, and is scarcely twice 

 as long as wide, is anteriorly distinctly convex and posteriorly beyond 

 well-marked basal elevation is first a trifle concave and then distinctly 

 convex. Chela 2*8 as long as wide ; hand, which is 1*2 as wide as the 

 tibia, is l"! deeper than wide and 1*5 as long as the fingers, which are 

 about as long as hand is deep. Tibia of the first pair of legs 1'3 as 

 long as the tarsus, which is 4 as long as deep ; femur IV. 2'3 as long- 

 as deep, and 1*3 lower than the tarsus is deep. 

 CepTialotliorax. — The ocular spots are indistinct. The cephalothorax, 

 which is distinctly longer than wide, shows no trace of transverse stripes, is 

 smooth and provided with moderately long, almost simple hairs. 



Abdomen. — The very long and slender abdomen, which has the fourth to 

 the tenth tergites longitudinally divided and trace of division in the first 

 three, has smooth tergal sclerites. The tergites have from 10-14 fairly long 

 and pointed hairs along the hindmost margin, in addition to six in front in 

 the median segments ; the " tactile " hairs were missing in the specimen 

 examined. 



Antennce. — The galea is broken, but extends distinctly beyond the terminal 

 hair. The flagellum consists of four hairs, of which the anterior has long 

 marginal teeth. 



Palps (PI. 8. figs. 17-19). — The maxillce are smooth. The palps are almost 

 smooth except anteriorly, where they are minutely granular. The fairly long 

 and stiff hairs are pointed and almost simple ; the number and arrangement 

 of the long, slender, and completely simple hairs are probably as in 

 Ch. javanus, Thorell {cf. p. 60). The trochanter, which is about 1*5 as long 

 as wide, is only slightly convex anteriorly, but posteriorly produced into a 

 rounded, rather short protuberance ; dorsally it is prolonged into a fairly
