Peckham’s description of this species in ‘‘ Ant-like Spiders’? 
holds for these specimens. A few additional observations may, 
however, be added. ‘The eyes of the 2nd row are situated about 
midway between the first and the 3rd rows; there are 7 teeth 
on the inferior and 4 on the superior margin of the falces ; there 
are 4 pairs of spines on the anterior tibia and 2 pairs on the 
anterior metatarsus, while there are 3 pairs of spines on the tibia 
of the 2nd leg. 
The ist tibia is black-lined anteriorly and the femur posterior- 
ly; similarly, the 2nd femur has a black line on its anterior 
margin ‘The abdomen is olivaceous with a dark band running 
across the middle of the posterior two-thirds of the abdomen, 
which is depressed ventrally. 
The epigynum has a characteristic shape (pl. xxxii, fig. 3). 
There are two obliquely elliptical white areas, between which lie the 
chitinous genitalia. The latter consist of two halves which meet 
about midway but are separated anteriorly and posteriorly.

This is the commonest ant-like spider in India. The Museum 
collection contains 6 specimens of the male of this species, of which 
3 were collected by Prof. Ramunni Menon at Madras, one by 
Mr. Gravely and another by Mr. I,. L. Fermor at Calcutta, and the 
last has been obtained from the Nicobars.! 
One female specimen from Madras was collected by Prof. 
Ramunni Menon and another by Mr. Paiva from Katihar (Purnea 
district) in Bihar.

(Calcutta o specimen). 
Total length 7 mm. 
Cephalothorax: length 3° mm.; width 1°5 mm. 
Falces 2°I mm. 
Legs 4132. 
The specimens agree in almost all essential features with the 
description given by Thorell; a few minor points brought out by 
the examination of the males may be noted here. It may be 
‘mentioned that I have compared these specimens carefully with 
an identified specimen of this species sent to the Indian Museum 
by A. S. Hirst from the Brit. Mus. collection. 
The falces are divisible into two portions: asmall basal portion 
from which the greater part of the falx is separated by a con- 
striction. This basal portion is very prominent in some speci- 
mens, while in others it is sunk in the cephalothorax, but can be 
1 Since the above was written I have got three more ¢ specimens, one collected 
by Mr. Gravely at Calcutta, the other by Mr. Kemp at Port Blair (Andamans ) 
and the third by Mr, Paiva at Katihar, Purnea (Bihar).
