Tills species Is very closely allied to Floweri (from rinaiirr). 

 It is, however, quite distinct, differing in the form of the 

 tibial spur, the form and length of the central lobe of the 

 palpal organs, in tlie presence of a distinct spur at the base 

 of the tarsus of the palpus, and by the absence of any abdo- 

 minal pattern of white pubescence.

 Ilal). Ceylon (77nva{tes). 



(^ . Tot. len. 1P5 mm., carap. 12x5; legs 1. 26, il. 24, 

 iii. 20, iv. 29; pat. +tib. 1. 9, ill. 6, iv. 8'5 ; prot. i. 6'75, 

 iii. 4-75, iv. 8. 



Colour. Legs and carapace mahogany-brown, clothed with 

 grey pubescence, the latter being too much worn to enable 

 one to give any accurate description of its distribution. The 

 protarsi and tarsi of the legs are tinged with a deeper brown. 

 Abdomen dull rcd-ochreous, clothed with grey pubescence, 

 with five spots of brown hair on each side and a central ojie 

 on the dorsal line, this spot uniting with the laterals on either 

 side forms a A -shaped mark. Ventral area black, with five 

 lines of white spots. 



Structure. Carapace raised behind, slightly bilobale. 

 Eyes. Second row straight by anterior margins. Central 

 quadrangle broader than long, narrower in front. Central 

 anteriors much smaller than central posteriors. Clypeus 

 equal to the diameter of an anterior central eye. 



Tibia of pedipalp at least five times longer than its 

 diameter, bearing on the outer side towards the apex a very 

 short blunt spur, scarcely one third the width of the segment. 

 Tarsal segment very short, about two thirds the length of 

 the tibia. 



A single adult male was taken in Ceylon by Mr. Thwaites. 



A comparison of the drawing of the tibia of the pedipalp 



of this species with those of Tlwrellii and ceylonensis, both 



from Ceylon, will demonstrate the distinctness of the species.

 An adult male and leinale named by Mr. Simon are m the 

 collection of the Katural History Museum. The female can 

 best be recognized by the vulva, and the male from its
