 further ou.

 Tctragnatha gracilis. Gravely, 1921, p. 411. 



From India and Ceylon to Celebes and Amboina. T^iffering 

 from all other known Oriental species in having the anterior medi- 

 an eyes much nearer together than the posterior medians. The 

 characters in which T. ironto, Thorell, differs do not appear to be 

 constant (see below, p. 437) and Thorell's description of T. tridens 

 agrees perfectly with the male of the present species. 



Tctragnatha gracillima (Thorell). 



Limoxera gracilliina, Thorell, l8go, pp. 227-230. 



From Sumatra. I,ateral eyes very slightly nearer together 

 than medians. 



Female. Chelicerae less than half as long as carapace. 

 First of dorsal five teeth stouter but not longer than second, 

 remainder diminishing ; second widely separated from first, being 

 opposite the fourth of the five ventrals all of which are small, first 

 twice as long as second and narrowly separated from it. Fang 

 scarcely half as long as basal joint, unarmed. 



Male unknown. 



Tctragnatha hamata, Thorell. 



Tctragnatha hamata, Thorell, 1898, pp. 326-328. 



From Carennee. 



Female unknown. 



Male. Chelicerae a little shorter than carapace. Subapical 

 spine acuminate but obliquely truncate and subemarginate at 

 apex, with two strong teeth below and to the outer side of it. The 

 ventral series consists of these two teeth and a diminishing series 

 of about seven more, which commences some distance behind them. 

 The dorsal series commences with two or three small teeth situated 

 obliquely and close to the base of the fang, and very close to each
