Suborder ARANEAE VERAE. 

 Family Uloboridae. 



A small black Uloborus is common among webs of Cyrto- 

 phora cicairosa. This or a closelj' allied species appears to have 

 a wide distribution in India and Burma, where it occurs in 

 association with C. citricola as well as with C. cicatrosa. It is 

 much smaller than U. servidus, Simon, which was found in asso- 

 ciation with a Cyrtophora of great size in Venezuela (Simon 1892 a, 

 p. 213 ; 1892 b,p. 427). 



The Uloborid already reported from Cochin (Gravely, 1915 b, 

 p. 534), which spins a remarkable snare consisting of a horizontal 

 orb- web above a funnel of different mesh, has also been found on 

 Barkuda Island. It belongs to the genus Uloborus and though dis- 

 tinct from, is evidently related to, U. quadri-tuberculatus , Thorell 

 in Mss., which is figured with its similar web by Workman (1896, 

 pi. 18). 



Family Dictynidae. 



Amaurobius sp. 



A brown spider (becoming paler in spirit) of moderate size, 

 spinning an untidy cobweb on leaves and twigs round about its 

 lair. The lair is usuall}' concealed in one or two curled leaflets, 

 often of the common jungle shrub, Glycosinis pentaphylla , or may 

 be beneath the spines of a Prickly Pear. 



A single male was obtained in August. 



This appears to be the first record of the genus from India, 

 though A. taprokanicola was described b}- Strand (1907, p. no, 

 figs. 49-50^) from Ceylon. In the absence of the description of 

 .•1. taprobanicola and of specimens of other species for comparison 

 I prefer to leave the Barkuda form undescribed at present. 



Dictyna spp, 

 PI. xvii, figs. 2-3. 



Two of the Barkuda spiders appear to belong to the genus 

 Dictyna. One is a minute brown spider which spins untidj' little 

 cobwebs over the twigs of a Caperid bush, hiding itself in the fork 

 formed by a leaf stalk or a second twig. 



The other is a small bright green spider with whitish raid- 

 dorsal line on the carapace and lateral hues on the abdomen, the 

 latter united dorsally by three more or less distinct transverse 

 whitish lines. Both sexes spin little white sheets across a sHghtly 

 curved leaflet (pi. xvii, figs. 2-3), usually of Glycosinis pentaphylla. 

 and live singly beneath them. They mature in October or there- 

 abouts, after which the female depo-^its a number of clusters of 

 eggs on the surface of the leaf which has formed her home. The 

 European D. vindissiina (Walckenaer^ appears to have similar 

 habits (Simon, 1802 a, p. 234).
