Material. A single adult male and numerous females from the 

 Nicobars. (Ind. Mus. coll. and Brit. Mus. coll.) 



Remarks. This interesting species is chiefly characterised by 

 the structure of its stridulatory apparatus, the half which is situated 

 on the coxa of the palp being exceptionally simple and elementary 

 in character. I think that it would be best to institute a subgenus 

 of Chilohrachys for it, and I propose the name Neochilobrachys for 

 this new subgenus. 



AnnandaIvIEIvIvA, gen, nov. 



Carapace. Thoracic fovea straight, transverse. Eyes of an- 

 terior row strongly procurved. 



Labium broader than long and spinulose apically. 



Sternum. Posterior sigilla of small size, widely separated from 

 one another and separated from the margin by about one-and-a-half 

 times their diameter. 



Mandibles with their inner surfaces furnished with a stridula- 

 tory organ consisting of an oblique row of spines, few in number ; 

 the two halves of the organ being exactl}^ similar in structure. 



Legs slender. Tibiae and metatarsi of anterior pairs armed 

 with apical spines alone, below ; tibiae and metatarsi of posterior 

 legs armed with a number of spines. 



Spinnerets. Upper spinnerets four-jointed, the apical segment 

 being longer than the penultimate segment. 



* Annandaliella travancorica, sp. nov. 



5 . Colour (specimen rubbed) pale yellowish brown. 



Carapace equal in length to patella and tibia of first or fourth 

 legs, considerably longer than patella and tibia of second and a little 

 shorter than patella, tibia and tarsus of palp. Anterior median 

 eyes further apart from one another than from the elongate anterior 

 laterals, and of smaller size. 



Legs. Metatarsus of fourth leg equal in length to patella and 

 tibia of second and almost equal to metatarsus and tarsus of third. 

 Patella and tibia of third leg about equal to patella and tibia of palp. 



Metatarsus of first leg scopulate for almost its entire length ; 

 metatarsus of fourth only scopulate at the apex. Tarsal scopula 

 of first leg undivided, that of the second faintly divided, and the 

 scopulae of the tarsi of the third and fourth distinctly divided by a 

 line of setae. 



Tibia of first leg, and metatarsi of first and second, armed 

 below with a single apical spine ; tibia of second with three apical 

 spines. Tibia of fourth furnished ventrally with two strong spines 

 and also with a number of apical spines ; its anterior side with two 

 spines, and the posterior with four. Metatarsus of fourth leg with 

 I.I antero-dorsal spines and with postero-dorsal spines corresponding 



1 The stridulatory organ of this spider is described and figured in Ann. Mag. 

 Nat. Hist. (8), ii, p. 402, text-fig. 3 (1908).
