The Spiders here described were collected by Dr. Nelson 

 Annandale and Mr. H. C. Robinson in the Malay States in the 

 years 1901-2, and are now under the charge of the British 

 Museum, South Kensington. 



The specimens examined were : — 



Thomisim. 



Strigophis 

 A mycicea 

 Epidhis . . 



SalticiDjE. 



Myrmarachne 55 



Agorius 1 



Many of these were accompanied by ants which have been 

 numbered for reference, but which have not been identified. 



The species of Thomisidae and of Agorius are known. Of 

 Myrmarachne, with the exception of M. maxillosa, of which there 

 are 13 specimens, all seem to be new species. Material in the 

 British Museum available for comparison is, however, scanty, and 

 the descriptions and especially the figures dealing with known 

 species are so scattered and often inadequate, that certainty on 

 this point is at present impossible. 



Myrmarachne maxillosa female was very common, and it is 

 curious that no male was found. In general shape M. biseratensis 

 is very much like it, but it differs in teeth and tibial spines from 

 all previous descriptions of the male of that species. It may 

 ultimately prove to be a variety.
