162 Christmas Inland. 



" Common on the island. Found under loose bark ; also in tent 

 at night and in roof of outbuildings, etc." 



A single mutilated female example of this species was brought 

 by Mr. J. J. Lister from Christmas Island in 1888, and wrongly 

 identified by me as H. venatoria, L. An examination of -svell- 

 preserved material, consisting of both young and adults of both 

 sexes, proves the species to be quite distinct from venatoria. It 

 differs from all the known species of Heteropoda, in having the 

 upper half of the mandibles thickly clothed with long hairs, with 

 the apical half naked, exactly as occurs in the genus Panaretus. 

 In this particular it constitutes an intermediate link between 

 Panaretus and Heteropoda, both of which are represented by 

 several species in the Malaysian area. From the known species 

 of Panaretus, U. listeri differs in having the posterior portion of 

 the carapace as high and not higher than the anterior. 



In addition to the large specimens of this species described above 

 and figured, Mr. Andrews procured a number of small examples 

 of Heteropoda, containing both adults and young, which at first 

 sight appear to belong to a distinct species. But since the vulva 

 and palpi are practically identical in structure with those of the 

 larger examples, I conclude that the smaller examples are merely 

 dwarfed representatives of the same species as the larger. 



In addition to the spiders above recorded Mr. Andrews brought 

 back — 



1. A single sub-adult female trapdoor spider belonging to the 



family Barychelida) and possibly referable to the genus 

 Encyocrypta. The arrangement of the eyes is less specialized 

 than in that genus, the anterior laterals being further apart. 

 But this primitiveness in the eyes in the Christmas Island 

 specimen is probably to be attiibutcd to immaturity. 



2. Several sub-adult specimens of what is probably a new species 



of Xysticus. 

 8. Immature specimens of a species of Araneiis — perhaps 

 A. nauticus, L. K. 



4. A single adult female referable to the genus Litliyphantes. 



5. A few immature specimens of a species of Oxyopes. 



6. Several small Attidae of various kinds, which I refrain from 



determining.
