1877.| ON SPIDERS FROM DUKE-OF-YORK ISLAND ETC. 283 
CHILOGNATHA. 
Sprrospo.us, Brandt. 
SPIROBOLUS CINCTIPES, 0. sp. 
@. Reddish tawny, with the hind borders of the segments 
blackish ; legs and antennze grey, banded with white: a linear im- 
pression down the centre of the head ; first segment rounded at the 
lateral angles, with a marginal ridge, not striated; remaining seg- 
ments with lateral irregular striations ; preanal segment subspinose 
behind, not extending to a level with the extremity of the anal 
valves; fifty-five dorsal segments ; preanal plate subtriangular, com- 
pressed ; antennee short, thick, with all the joints excepting the last 
of nearly equal length, the last joint forming a terminal button ; 
eyes in a rounded subtriangiar mass, blackish, grouped in six rows ; 
103 pairs of legs; length 3 inches 10 lines. 
Allied to S. gaimardi of Gervais from New Ireland, but with a 
greater number of segments and legs, and very different coloration. 
Several examples of this species were obtained ; but, unfortunately, all 
but one were broken beyond the possibility of rearrangement of the 
parts: the type, being much larger than the others, and being 
merely separated in the middle, was easily readjusted. 
3. On some Spiders collected by the Rev. George Brown 
in Duke-of-York Island, New Britain, and New Ireland. 
By the Rev. O. P. Camsrinexr, M.A., C.M.Z.S. 
[Received March 12 1877.] 
I am much indebted to the Secretary of the Zoological Society for 
the opportunity of examining a few Spiders collected, among numerous 
other naturai-history objects, by the Rev. George Brown in Duke- 
of-York Island, New Britain, and New Ireland. ‘Two of these spiders, 
an Argiope (family Epeirides) and a Sarotes (family Thomisides) 
appear to me to be undescribed ; and upon the former I have taken 
the liberty to confer Mr. Brown’s name. Another of the Spiders, a 
very distinct and handsome Gasteracantha (G. panisicca, Butl.), has 
been already described, but only from dried examples, which must 
have wholly lost their characteristic colours and markings; I have 
therefore subjoined a description of its colours and markings from 
Mr. Brown’s specimens. The remaining Spider is one of those 
gigantic Nephile (specially characterized by two small tubercular 
eminences on the middle of the cephalothorax) of the orbicular snares 
of which most natural-history collectors in exotic regions bring home 
startling accounts, but of which scarcely any collectors have yet been 
sufficiently observant to detect the minute males. This, however, is the 
sex in which the araneologist expects to find the most conclusive spe- 
cific characters ; and, indeed, until the males come to hand, it is often 
exceedingly difficult to give a reliable opinion upon the specifie identity 
of these and many other Spiders.
