distinct transverse grooves. The tergal sclerites are also granular, with more or less 

 distinctly clavate hairs along the hindmost row in addition to hairs (generally six) in 

 front of the row in the median segments at least. The genital area of the male is very 

 similar to that of Ch. suhruher Sim. {cf. 20. p. 121, pi. iii. fig. 7 h) ; the anterior 

 plate, which is wider than long, has a posterior marginal seam, and is shorter, as well 

 as narrower, than the posterior plate ; a great number of accessory club-shaped glands 

 are present. The sternites of the males are beset with short spines, arranged in well- 

 defined areas ; the number of the spines on each segment, the shape of the area in 

 which they are placed, and the number of the sternites, which are adorned with such 

 areas, vary considerably in difi'erent species : in Ch. murrayi Poc. the fourth to the 

 tenth sternites bear numerous spines, and in Ch. canestrinii Balz. only the seventh and 

 the eighth sternites bear areas of a somewhat remarkable structure {cf. EUingsen, 32. 

 pp. 13-14; With, 20. pp. 129, 158, & 162, tab. iii. figs. 7 J & 85; also PL XXIX. 

 figs. 3 «, 5 a, & 6 a) *. The galea, in the female of the South-American species is 

 long and slender, distinctly extending beyond the terminal hair and provided with 

 about five terminal branches, while in the male it extends scarcely at all beyond the 

 terminal hair and its teeth are more or less obsolete ; in the two Asiatic species 

 examined the galea has a somewhat different structure {cf. 20. tab. iii. figs. 1 d &. 

 9>c-d). The flagellum always consists of four hairs {cf. 20. p. 158). The palps are 

 generally longer and more slender in the males than in the females, but seldom in so 

 marked a degree as in Ch. longichelifer Balz. ; the fingers never bear accessory teeth 

 and seldom gape distinctly in the male. The articulation between the two parts of 

 the femur of the first pair of legs is very similar to that of Ch. suhruher Sim., but 

 seems to be somewhat better developed {cf. 20. p. 37, figs. 5 a, h). The articular 

 cavity is not very wide, slightly oblique, with the anterior and posterior condyli 

 opposite to each other, or the latter more dorsally placed. Tiie subterminal hair has 

 no tooth, and the dorsal " tactile " hair of the fourth pair of legs is median or placed 

 beyond the middle ; the proximal joints of the legs are more or less granular, and the 

 claws are always simple. 



The following 14 species may with certainty be referred to this group, but without 

 doubt the number will be largely augmented by described as well as undescribed 

 species, when naturalists, working at this group, have realised the value of a more 

 thorough investigation. I am disposed to think that the group of Ch. suhruher Sim. 

 is the central one of the whole subfamily, but before settling the question definitely 

 a comparative-anatomical investigation of the male organs of the difi'erent types of 

 Chelifer Geoff'., as well as of the Garypidce Hans., is absolutely necessary.

* Alb. Tullgren (23. p. 33) -writes about Cli. torulosvs Tullgr., which belongs to the group of Ch. cnn- 

 croides L. : — " Die vordere Ventralplatten scheinen daneben eine transversale Area kurzer Stacheln (wie 

 Ch. angulatus EU.) zu besitzen."
