and is slightly constricted on the inner side at aliont the middle. 

 The male appears to differ from that of E. javnna chiefly in havins;; 

 the long apical tooth of the ventral row followed by about ten 

 instead of five small teeth, this row consequently extending 

 throughout the whole length of the joint. 



E. isidis apparently also differs from E. anguilla and E. javana 

 in the female sex, of which alone the description is known to 

 me, in lacking the stout tubercle near the middle of the upper 

 and inner side of the basal joint of the chelicerae ; and it has only 

 three strong teeth on the ventral margin of the fang-groove.

In this species, as in the various species of TefragnatJia, the 

 chelicerae are relatively short in young specimens, and the char- 

 acteristic dentition is not developed. This develops, however, in 

 specimens which I think can hardh' be mature ; and mature or 

 apparently mature specimens of both sexes vary greatly in size 

 {a», 6-10 mm.. 2 12-18 mm. long, excluding chelicerae). The 

 size and general development of the teeth on the chelicerae also 

 varies considerably, though their arrangement is approximately 

 constant. In the female the first tooth on either side of the fang- 

 groove is situated at the base of the fang ; in the ventral row the 

 second tooth is about twice as far from the first as from the third 

 and the third is as a rule (but not invariably) distinctly further 

 from the second than from the fourth ; in the dorsal row the second 

 is opposite the third ventral, the third opposite the fourth ventral 

 and so on. Each row consists of from about six to eight teeth, 

 usualh' one or two fewer in the dorsal row than in the ventral. 

 In addition to these teeth there is a conical denticle at about the 

 middle of the dorsal surface on the inner side. As a rule this is very 

 large in well-developed specimens, but sometimes it is more indis- 

 tinct. It is not developed in immature specimens. In mature 

 specimens as a rule there is also a small but strongly chitinized coni- 

 cal denticle on the outer side close to the apex ; this is, however, less 

 constant and is likewise absent in immature forms. The fang is 

 unarmed and slightly curved. 



In the chelicerae of the male the basal joint is armed at
