l)y the internal sclerite, which in A. pulchella is \-Qvy large and 

 situated beside the anterior wall of the aperture, and in A. anasuja 

 is smaller and situated beside the posterior wall (see text-figs. 3a, h). 

 The anterior median eyes are, moreover, much more prominent in 

 A. pulchella than in A. anasuja in the female sex. But I have been 

 unable to find any character by which to distinguish the males. 

 Both species occur on Barkuda Island.

The dome-shaped webs of this spider are very abundant 

 among Prickly Pear. They are frequented by the slender Re- 

 duviid bug Eugubinus reticolus, hitherto recorded only from 

 Bengal, and also by E. intrudeuR, hitherto only recorded from 

 Cochin. I have nothing to add to my previous record of the 

 habits of these bugs, which appear to live mainly on the eggs of 

 this spider (19156, pp. 512-3). Single specimens of the larger 

 and still more slender Reduviid Iscknobaena hcnrici have twice 

 been found in the webs. I have not been able to make aiiy 

 definite observations on this association, but it isunlikel}^, I think, 

 to have been accidental, botli on account of the similarity of form 

 between Ischnobaena and Eugubinus and because both seem equal- 

 ly at ease in the webs. The presence of cast skins, moreover, 

 proved that the specimens had grown up in the webs from an 

 early stage. 



The association of a Uloborid and a Theridiid with C. cica- 

 trosa has already been referred to above (pp. 405, 410).

This species is represented in the Indian Museum collection 

 from many localities and proves to be extremely variable both 

 in structure and in colour. The young may be brownish, but are 

 frequently of a glistening metallic silver. The silver colouration 

 may be more or less persistent in the adult, in which various 

 shades of ochre, brown or black more or less marbled with fainter 

 tints are, however, more usual. 



The sternum is usuallj^ dark brown with a transverse yellow 

 band between the first legs, a spot or radial streak of yellow op- 

 posite the bases of the second and third legs and a terminal spot 

 or longitudinal streak between the fourth legs (as in types of C. 

 spirifera). It may, however, be uniformly black or uniformly 

 white (as in the type of C. albisternus) according to the extent 

 and density of the difTerent pigments. 



I can find no constant structural difference between C. albis- 

 ternus and C. spirifera. The anterior and posterior eyes of the 

 latter do indeed at first sight appear to be more widely separated
