 well as liiose ol' Chtlioniiis C. K. cross eacli olhcr with llit-ir tips, when closed, 

 leaxiiig no space between in the l'ornici- genus, hnt a small one in the latter on 

 acconnl of the curving of the lingers. In hieohisiiiiii B(tl:anii With (21. pi. X, fig. 2a) 

 and in hleoroncus Mexicanns Bks. (pi. IX, fig. 2d) holh belonging to the Pseiido- 

 hisiiiiae Hans, the space between the lingers is moderate and they cross each other 

 with their outmost tips. In Garypiis L. Kock, but chietly in (Jhelifer Geof. this space 

 is well marked, and in the former genus almost filled with the lamina interior, in 

 the latter completely so. 



The antennae are most often smooth, but sometimes provided with a number 

 of granules or s^)ines e. g. Clitiwnius ferrihilis n. sp. (PI. I, fig. 1 c). The antennae 

 bear a number of hairs, which are long, slender and simple; only in species of 

 Chelifer Geof. those of the hand are provided with a distal short branch or tooth. 

 In the arrangement and number of the "lyriform fissures" (cf. Hansen pp. 204 and 

 209) there seems to be a difference between the genera, but as I have not studied 

 this matter thoroughly I refer to the figures, given by Dr. Hansen and myself. 



Marginal teeth. The upper and inner margins of the two fingers are in 

 both suborders mounted with a row of teeth; these teeth are especially well 

 developed within the Hemictenodactyli, and their number and arrangement furnish 

 useful systematic characters in species of Ideobisium Balz. and Chthoniiis C. K. 

 (PI. I, figs. 1 c-d, 4a-b, 5 a) (cf. Hansen 49. tab. V, tigs. 5 and 12; Balzan 46. tab. XVII, 

 fig. 23b; Balzan 12. pi. 12, figs. 31-34a; With 21. pi. IX, figs. 2 c-d, and pi. X, 2 a-b). 

 These marginal teeth are slightly developed in the Panctenodactyli, especially the 

 Cheliferidae Hans.; the immovable finger has a marginal row, consisting of about 

 5 — 10 more or less indistinct teeth (PI. II, fig. (i a, pi. IV, fig. 4a); the movable finger 

 has in most species of Chelifer Geof., perhaps in all, and at least in many of 

 Gor;//3as L. Kock and Olpiuni L. Kock one or two teeth behind the distinct terminal 

 hook (PI. II, fig. 7d, pi. Ill, figs. 8d-e). 



Flagellum. The flagellum attains its highest development in Chthonins CK. 

 for inst. in Ch. Raiji L. K. (Hansen 49. lab. V, fig. 12 f) and Ch. lerribilis n. sp. (PI. I, 

 fig. Ic), in which it consists of about ten (most often unilaterally) ])innate hairs, 

 placed at the root of the movable finger in a thinly skinned spot and arranged in 

 one or two tufts (cf. Daday 14. tab. XI, fig. 1). Lechytia Balz.. which seems to be 

 nearly related to CJithoniiis C. K., has according to Balzan (12. [). 499) a flagellum, 

 consisting of a few almost simple hairs, placed in a row. A similar position, being 

 in a long regular row, is characteristic of the Obisiinae Dad. and most typically 

 developed in Blottiras spelaeus Schiödte, where about ten pinnate hairs are placed 

 in a very long row, extending from the middle of the hand to the root of the 

 movable finger. In Roncus alpinus L. Kock there are about nine long partly simple 

 hairs, placed in a similar manner, and in Obisiuni niuscorun} Leach, eight bristles, 

 of dilTerent size (Hansen 49. tab. V, fig. 9 f ). The flagellum of the Pseudobisiinae 

 Hans, is varied in its structure, though as a whole of a rather simple nature, It
