Family Thomisides. 



Genus Amycle (Cambr.). 



Amycle albomoculata, n. sp. 



This spider is remarkably similar to A. forticeps (Cambr.) 

 (P. Z. S. 1873, p. 122, pi. 13. fig. 6) both in form, general 

 colour, and structure. In the present species, however, the 

 abdomen has none of the dark markings of A.forticeps, but 

 has instead on the upperside a tolerably regular pattern of 

 distinct white spots of different sizes ; these are most con- 

 spicuous in the female ; they form two longitudinal lines 

 enclosing a very elongated subdiamond-shaped area, with a 

 few other similar spots on the sides. The two round black 

 blotches so conspicuous on the hinder part of the upperside of 

 the abdomen of A. forticeps are also present in A. albomacu- 

 lata. It is possible that the comparison of a lengthened series 

 of examples of both these species might prove them to be 

 merely varieties of each other ; but as the only two examples 

 of the present spider that have yet been found differ in the 

 above-mentioned particulars from all the six known examples 

 of A. forticeps, and the respective localities of the two are 

 so widely removed from each other, I have thought it best to 

 record the present as a distinct species. 



The occurrence of this genus in Northern Australia (whence 

 it was received by Mr. H. H. B. Bradley and kindly submitted 

 to me) so soon after its first discovery in Ceylon, is, like that 

 of Miagrammopes (supra , p. 177), exceedingly interesting ; one 

 would expect now to find these, as well as other Ceylon 

 genera and species, occurring all along the Sumatran and 

 Javan chain of islands, which form the only present con- 

 nexion of any kind with Australia. 



Two examples, an adult male and female, were received from 

 Mr. Bradley. 



Family Salticides. 



Genus Salticus (Latr.). 



Salticus (Attus, Sim.) volans, n. sp. Plate XVII. fig. 4. 



Adult male, length rather above 2 lines. 



The ccphalothorax of this spider is of ordinary form ; the 

 thoracic region and sides of the caput are black, with a margin 

 of white hairs ; the upper part of the caput between the eyes 

 is banded longitudinally with alternate bands of a soft greyish 

 green and bright scarlet, three of the former to two of the 

 latter ; and on the upper part of the thorax are three large 

 spots of white hairs in a transverse row, the lateral spots being
