hitherto certain $ Thelechoris have Leeu described as Ischnothele, 

 whilst before the genera were merged, g Ischnothele were referred 

 to Thelechoris; thus the palp figured in Sim. Hist. Nat. des 

 Araign. 2nd ed. vol. i, 1892, p. 70, as of Thelechoris, is characteristic 

 of Ischnothele. Hence as up till now only Ischnothele g <$ were 

 known, and the ? ? of both genera were much alike, the synonymy 

 was probably established on 'account of the cross descriptions referred 

 to above. The $ Thelechoris described below makes it clear that 

 the genera, are distinct, and the ? characters set out by Simon in 

 Hist. Nat. des Araign. 1892, p. 187, should be sufficient to separate 

 T/iflechoris from Ischnothele as instituted by Ausserer in Verh. Zool. 

 But. Ges. Wieii. 1875, pp. 162 and 163.

$ Colour as in female; perhaps slightly lighter and less infu seated; 

 spinners pale and posterior ones less darkly ringed at apices of 

 segments. Under abdomen paler than dorsal surface; genital plate 

 and lung operculae brown; legs faintly banded by olive infuscations. 



Carapace as long as metatarsus IV, and equal to metatarsus and 

 tarsus of 1st leg. Fovea slightly recurved. 



I-Ji/i's. Anterior row equidistant, strongly recui'ved. Medians 

 large, round, and almost equalling in size the broadly oval, oblique, 

 lateral eyes. Posterior row straight; medians small, oval, touching 

 laterals, which are smaller than anterior laterals. 



linliiinii and coxae of pedipalps muticous ; white inner border of the 

 latter is raised above the rest and separated by a fine groove. 



Ghelicerae with 10-11 teeth on inner border, alternately large and 

 small, especially anteriorly. 



Spinners. Posterior ones 7'5 mm. long; about equal to patella, 

 tibia, metatarsus and tarsus of 1st leg; apical joint equal to basal 

 and median joints in length. 



Legs in order 4, 3, 2, 1. Metatarsi much longer than tarsi, 

 especially in legs 3 and 4 ; metatarsus I straight and moderately 

 spined, especially at apex below ; metatarsus II slightly curved 

 inwards towards base, where it is also stouter ; provided on lower 

 surface, towards base of inner side, with a small tubercle bearing an
