Puri District, both on the Chilka Lake ; Balighai, further north 

 in the Puri District. 



Like T. mandibulata this species is nocturnal ; but instead of 

 frequenting water it spins its webs among bushes in the jungle. 

 The bright green of the sides of its abdomen tone with the red- 

 dish brown of its back and legs in such a way as to make it very 

 inconspicuous on the leafy twigs of the bushes among which its 

 web is spun, and where it rests by day. 



In life it may readily be recognized by its bright colours and 

 very long and strongly di^-aricate chelicerae ; but the charac- 

 teristic colouration soon disappears in spirit. The female may, 

 however, be recognized by a semicircular ridge that extends 

 between the first spines of dorsal and ventral rows respectively, 

 these spines being the largest, with the ventral much larger than the 

 dorsal ; the largest of the remaining spines are situated on the strong 

 curve near the base of the joint instead of distally as is usual. 



The male may be recognized by the fact that the first dorsal 

 and the subapical spines are of about equal length, the former 

 slightly shorter and thicker than the latter, and much longer 

 than any of the other spines. The fang is armed with a strong- 

 truncate tooth on the inner side of the basal bend as in the pre- 

 ceding species. 



Genus Eucta, Simon. 



Three species, E. caudicula, Karsch (1879, pp. 66, 67, pi. i, 

 figs, 4-4^), originally described from Japan, E. isidis, Simon 

 (1800, p. 34), originally described from Egypt, and E. javana, 

 Thorell (1889-90, pp. 236-239 o* , 1895, pp. 146-147, 2 ), origin- 

 ally described from Java are said to occur in India and Burma (see 

 Simon, 1885, p. 450 and 1892, p. 722 ; Sheriffs, 1919, p. .^32) ; 

 and a fourth, E. anguilla, Thorell (1877, pp. 443-445) has been 

 described Irom Celebes. 



The specimens before me both male and female all agree with 

 Thorell's description of E. javana, except that the teeth bordering 

 the fang-groove of the female are somewhat variable in number and 

 are usually slightly more numerous, as in .4. angailla. It seems 

 possible, therefore, that these two species may prove to be identi- 

 cal; but the male of E. anguilla has not yet been described. 



E. caudicula is said by Sherifis (1919, p. 232) to have been re- 

 corded by Simon from India.' The female differs from those of 

 E. anguilla and E. javana in lacking the stout tubercle near the 

 middle of the upper and inner side of the basal joint of the che- 

 licerae. On the dorsal side of the fang groove it has one large 

 tooth at the base of the fang, one a little smaller at about the 

 middle, followed by a row of about five small ones. On the ven- 

 tral side there are three large teeth at the base of the fang, fol- 

 lowed after an interval by a row of about nine small ones. The 

 fang bears a small tubercle on the outer side just above the base, 



1 I ha\e not, however, succeeded in tracing this record.
