100 SCORPIONS, PEDIPALPI AND SPIDERS COLLECTED BY DR WILLEY 



structure of the tarsal segments of the legs of the 1st pair in the $ , the pi'ocess 

 on the 8th segment being considerably shorter and the basal emargination of the 

 9th segment much longer and defined posteriorly by a distinct tuberculiform eminence 

 (see Kraepelin, Abh. Nat. Ver. Hamburg, xv., p. 31, fig. 32 b, 1897). 



Family. Tarantulidae. 



Genus. Sarax, Sim. 



Sarax sarawakensis (Thorell). 



Charon sarawakensis, Thorell Ann. Mus. Genova (2), VI., p. 354, 1888. 

 Sarax saraiuakensis, Kraepelin, Abh. Nat. Ver. Hamburg xiil, p. 45, 1895. 

 Loc. New Britain. 



The specimens procured by Mr Willey have been compared with examples of 

 S. brachydactylus from Luzon, kindly presented to the British Museum by Mons. 

 Simon and with examples of the same genus collected by Mr Oates beneath stones 

 at low water in the Andaman Islands. The specimens appear to me to be co-specific. 

 Hence I am of opinion, with Prof. Kraepelin, that up to the present time only one 

 species of this genus is known, namely that to which Thorell gave the name sara- 

 wakensis. This species has been hitherto recorded from the Philippine Islands, Borneo 

 and New Guinea. 



Order. ARANEAE. 



Suborder. MYGALOMORPHAE. 



Family. Barychelidae. 



Genus. Encyocrypta, Simon.
