TWO NEW VICTORIAN SYMPHYLA OF THE GENUS 
HANSENIELLA.

Of tlie two species whicli are here described, one is the 
subject of a forthcoming embryological memoir, while the 
second will be referred to incidentally in the same work. As 
there appears to be no published record of either species, 
a taxonomic description is required. This forms the substance 
of the present paper. 
Although Symphylids are easily obtainable in Australia, 
even in large nmnbers, if sought for in their appropriate 
environment, there are only few accounts of their occurrence 
here, while the commonest genus, Hanseniella, does not seem 
to have been recorded at all. Attems (2) described from 
Western Australia, in 1911, under the name Scutigerella 
indecisa, a foiun which may prove to be a species of 
Hanseniella, B agnail’s (3) definition of that genus having 
not then been given. More recently Tilly ard (6) refers under 
the name Scolopendrella sp. to a form which, from the 
presence of coxal styles, clearly belongs to another family of 
Symphyla — the Scutigerellidae, and which, from the dimen- 
sions given, is probably the common Hanseniella agilis here 
described. 
In the following taxonomic description I have closely 
followed the method of Hansen (4), since direct comparison 
with his species can only be made on those characters to 
which he specifically refers. The terminology is also that of 
Hansen.

Hanseniella agilis, sp. nov. 
(Fig. 1, A-F.) 
Length 6*6' 5 mm. when fully grown; the full number of legs first appears 
in animals 4'2 mm. long. 
Head— hhont as broad as long, measuring in large adults 0 55 mm. m 
diameter; clothed with numerous equally spaced setae; the longest lateral 
setae equal in length to, and sometimes even considerably longer than, the 
breadth of the proximal antennal joints ; “central rod ’ not forked.
