112 Mr. C. J. With on Chelonethi 



Coxa. — The fourth pair of coxse is broad and widened out 

 distally. 



Le(/s. — The trochantin of the first pair of legs is short and 

 its tii)ia is distinctly longer than the tarsus. The femur of 

 the fonrth pair seems to be exceedingly long and compressed; 

 there does not appear to be any " tactile " hair at the base 

 of the tarsus. 



Co/our. — The cephalothorax, palps, and abdomen (according 

 to Whitens description) are deep brown ; the legs are pale. 

 " The claws with a greenish hue . . . ; abdominal segments 

 edged wi h palish" (White, op. cit. p. G). 



Measurements. — Cephalothorax about 1 mm. long. 



Palps: trochanter O'GOO (0-39.2); femur M76 (0-420); 

 tibia 1-092 (0--176) ; baud 1-0G4 (0-588), height 0-824.; 

 finger 0-784 mm. 



Material. — I have examined White's typical specimen 

 from New Zealand ; it was drii^d and badly damaged. I 

 hope it will be possible to recognize it from my description ; 

 it would probably have been impossible to do so from the 

 very short description given by White.

The tubercles of the trochanter of the palps are slightly 

 marked; the femur is twice as long as broad; the baud is 

 higher than broad and 1*4 longer than the fingers. Tlie 

 tarsi of the legs are much shorter than the tibiae ; the fourth 

 pair has a dorsal " tactile '' hair at the base ; the lateral 

 hairs near the base of the claws ;ire strongly curved. The 

 genital area is similar to that of Cli. hirmanicus , Thor. The 

 abdomen of the female is exceedingly long an 1 slender. 



I have examined Keyserling's original specimens.

cJ . Cephalothorax. — Two distinct eyes are present. The 

 cephalothorax, which is slightly longer than broad, becomes 

 gradually narrower towards the front margiu, which is 

 bordered with a clear membrane. The anterior transverse 

 groove is always straight in the middle, while the second is 

 moderately curved forwards ; the second tcrgite with a more 

 or less indistinct longitudinal groove. The skin is every- 

 where granular, with rather large and low granules, which 

 are always well separated from each other. Tiie short clavate 

 hairs of the head aud first tergite are placed without order
