slender, lightly curved, and imperfectly bifid dis tally ; below and 

 in front of it is a smaller conical spine directed forwards, and 

 below this again and slightly behind it, about opposite the base of 

 the subapical spine, is the first of the dorsal row of about seven 

 small teeth, arranged in descending series with a very long gap 

 between the first and second. Above the middle of this gap is a 

 pointed inwardly directed spine somewhat variable in length but 

 always well developed and, when large, often slightly geniculate. 

 The ventral margin of the fang-groove bears a pair of teeth at 

 the base of the fang, of which the second is the longest, followed 

 after a short interval by a somewhat uniform series of about six 

 teeth, all small, the middle of the interval being about opposite 

 the first dorsal tooth.

Total length up to about 9 mm, (chelicerae excluded) ; length 

 of carapace about 3 mm., maximum width of same fully 2 mm. in 

 female, barely 2 mm in male. The carapace and legs are yellowish, 

 the abdomen greyish. The carapace is moderately narrow and 

 almost parallel-sided in front, broadly rounded further back, rela- 

 tively longer and narrower in the male than in the female. The 

 abdomen is comparatively stout, as in T. piiclla. and much shorter 

 and more rounded than is usual in the genus, being scarcely more 

 than four times as long as it is thick. 



The ocular quadrangle is practically square, but the posterior 

 medians are separated by a very slightly wider space than the 

 anterior medians, and are fully one and a half times as far from 

 the anterior laterals as from each other. The anterior laterals 

 are very small, and about equidistant from the anterior medians 

 and posterior laterals, which latter are somewhat nearer to the 

 posterior medians than these are to each other. 



The chelicerae of the female are short and stout, between two 

 and three times as long as they are thick and about two-thirds as 

 long as the carapace. There are about seven teeth in each row, 

 the first in each (occasionally the first two ventrals) somewhat widely 

 separated from the rest, which are in diminishing series. First 

 dorsal larger than second, situated behind base of fang. First ven- 

 tral smaller than second, situated at base of fang. Second dorsal 

 about opposite fourth ventral. Fang short and stout, unarmed. 



The chelicerae of the male are much longer than those of the 

 female and nearly as long as the carapace. The subapical spine is
