(Plates 8-10.) 



All the species described in this paper belong to the British Museum, and 

 have been worked out at the request o£ the authorities o£ that institution. 

 The treatise is subdivided into two parts and a supplement. In the first 

 part eight, mostly new, species of Chelifer, Geoffrey, are described or 

 mentioned ; in the second part descriptions are given o£ several new and 

 old species of the Garypidce, Hansen (cf. below). The supplement deals with 

 the remarkable forms of galea found in Chiridium ferum, Simon, and Ideo- 

 roncus (" Roncus '"') Cambridgei, L. Koch. In the following pages I often 

 refer to other papers, previously published, dealing with the Chelonethi, as 

 well as one ("x4n Account of the South- American Clieliferince, Simon") which 

 I hope will be published in the ' Transactions ' of the Zoological Society. 



Part I. — Species of Cselifem. 



A. Species from Australasia. 



The Australian fauna of Chelonethi is, to judge from the number of species 

 which have as yet been recorded, only poor, but I think that the number of 

 species will be, at least, doubled when these vast regions have been properly 

 explored. Of the described fourteen species of CJieUferidce, Hansen, only two 

 are recorded from other regions ; but these statements are very doubtful (cf. 14. 

 p. 98) ; in this paper I am able to add four new species. Of these eighteen 

 species, eleven at least have accessory teeth on fingers of palps like the 

 Ch. cimicoides, F., group ; about five belong to the CJi. birmanicus ; Thorell, 

 and at least one (two ?) may be referred to the Ch. cancroides, L., group. 



The following synoptic key of the four herein described species must be 

 used in connection with that given in my earlier paper (14. pp. 95-97 and 

 15. p. 328) :— 



a. Hairs distinctly clavate. Femur 3 times as long as wide, 



concave anteriorly. Chela 4-3 as long as wide 1. Ch. vigil, sp. n. 



b. Hairs not distinctly clavate. Femur not more than 2'3 as 



long as wide, not concave anteriorly. Chela less than 

 3'4 as long as wide. 

 a'. Hairs short and obtuse. Hand at least 1'2 as long as 

 tibia and 1'6 as long as movable finger, which is much 

 longer than the immovable one 2. Ch. Keyserlingi, sp. n.
