Phormingochilus sp. ? 
A single young and unidentifiable example from Batjan. The genus was previously 
known from two species, both of which occur, so far as is at present known, only in Borneo. 
Subfam.: Selenocosmiinae Pocock. 
Selenocosmüdae Pocock, loc. eit. 
Genus Selenocosmia Ausserer.

Selenocosmia javanensıs (Walck.) 
Mygale javanensis Walckenaer, Ins. Apt. I, p. 216 (1837). 
A number of young specimens obtained at Buitenzorg are referred to this species. 
In a specimen 18 mm in length all the tarsal scopulae are completely divided by bands of 
setae and the inferior elaw is distinet upon the 4 * Jeg. 
Selenocosmia lanipes Ausserer. 
Verh. Zool.-Bot. Ges. Wien XXV, p. 187, pl. VII, fig. 32, 33 (1876). 
Three specimens obtained in Halmahera, a male and female at Soah Konorah and a 
female at Tobelo. The species was recorded by Ausserer from New-Guinea. 
The female is easily distinguishable from that of S. javanensis by having the carapace 
broader in proportion to its length and the legs longer and thinner. For example, in a speeimen 
of javanensis from the Salak in Java (R. Kirkpatrick), the length of the carapace exceeds the 
length of the patella and tibia of the 4: leg (20 : 18), whereas in lanipes the correspon- 
ding measurements are 18 : 18; again the carapace as compared to the tibia and protarsus 
of the 1 * leg is 20 : 20 in javanensis and 18 : 21!/ in lanipes.
