Cteniform Spiders of Ceylon ^ Burinah^ «Dc. 347 



Pedipalp. Tilda four times Ioniser than wide, fiirni.shetl on 

 outside at apex with a pair of excentrieally curviii,^ .spines or 

 sh^nth'r spurs ; the hjwcr compressed, siiuiou:*, bordered, spirali- 

 form, its apex aculeate, directed upwards ; the upper spur very 

 slender, but broadly dilate at base, its inner basal margin 

 irregularly dcntieulatc or si-n-ate, curving upwards, semi- 

 circular, attenuate towards apex, slightly sinuous imme- 

 diately before apex, which is dilate beneath and curved 

 strongly downwards. Tarsus one half longer than broad, 

 bulb small, central lobe four times longer than broad, re- 

 curved beneath at anterior margin ; a short curved spur 

 represents the unea. 



Colour similar to that of female. 



? . — Structure. Spines and general characters similar to 

 those of ThoreUii. Eyes similar to those in the male. 



Colour. Carapace dark olive-brown, with broad paler 

 central band, irregularly dilate on caput and before central 

 stria, narrowed to basal margin. Legs i., ii., and iii. olive- 

 brown, freckled with spots of grey pubescence; iv. olive- 

 brown, with ])ale narrow dorsal line on tib. and prot. iv. 

 (In the male all four pairs of legs are clothed with pale grey 

 pubescence.) 



Abdomen pale olive-brown, with central series of four (or 

 five) ]ialer chevron-like marks, each interstice picked out 

 with black. Sides marked with oblique lines of palo spot^. 

 Ventral surface covered with four conspicuous rows of white 

 spots and a pair of short central lines, becoming obsolete 

 before spinners. 



Vulca consisting of an elongate convex process, emarginate 

 on each side and clothed with hairs, presenting posteriorly a 

 cross piece whose ends curve sligiitly forwards. h\ front of 

 each arm^ in the angle formed by the junction of the two 

 limbs of this j^-shaped structure, lies a stout curved denticle, 

 its point directed upwards. The right side in the female before 

 me is malformed, so that the vulva is not bilaterally symme- 

 tricaL 



This species differs from the Bornean forms and from 

 ThoreUii by the closer proximity of the lateral anterior eyes 

 to the posterior centrals and the fact that the second row of 

 eyes is straight by their centres. Otherwise there is little to 

 choose between tliem in general character. 



That this form is closely allied to G. trabifer of Karseh 

 (which has nothing to do with trabifer, Thoreil, judging by 

 examples of the latter identified by Thoreil) is beyond doubt. 

 I fully expect them to be identical ; but without seeing 

 Karsch's type, and in the face of Karsch's figure of the vulva,
