Numerous examples of this enormous Epeirid were contained in 
Mr. Brown’s collections. It is most probably identical with Aranea 
maculata, Fabr. (A. longipes, Fabr., and Nephila maculata, Leach), 
as well as with WN. imperialis, Dol. I have myself received it from 
several parts of a wide exotic area, including Ceylon, Bombay, 
Manilla, Labuan, Hongkong, and Celebes; Mr. Brown’s examples 
now add another locality to those already recorded. In all of 
these localities it appears to be an abundant Spider. I have, how- 
ever, only as yet received the male from Manilla, Labuan, and 
Ceylon. This sex is so minute (scarcely measuring more than two 
lines in length, while the female reaches as much as two inches and 
even more) and is so unlike the female in form, colours, and struc- 
ture, that it is probably on these accounts overlooked by collectors 
who have not had their attention specially called to the fact of this 
great disparity between the sexes. 
Genus ArGiorE, Sav. 
ARGIOPE BROWNII, sp. 0. 
Adult female, length very nearly 9 lines. 
The cephalothoraz is as long as broad, the thorax nearly round, 
broader than long ; the caput is suddenly and strongly constricted 
laterally, and projects forward. The upper surface is flat, and its 
colour is dark brown; the occipital region, that of the four central 
eyes, and a longitudinal stripe running from them to the occiput 
are brownish orange-yellow ; the sides (towards the margins) are 
covered with small tubercular granulosities; and the normal con- 
verging indentations are covered with light-grey adpressed hairs ; 
the stripes of grey thus formed converge to the thoracic indentation, 
which is large and deep, and give the cephalothorax a very dis- 
tinctly radiated appearance. There are other hairs also; but these 
are the chief. 
The eyes of the four central and lateral pairs are seated on strong 
tubercular prominences and (looked at from the front) in a straight 
line. They are all small and do not differ very much in size; the 
four central eyes form a quadrangular figure whose fore side is 
shorter than the hinder one, and its longitudinal considerably longer 
than its transverse diameter ; the interval between the eyes of the 
fore central pair rather exceeds a diameter; and the height of the 
clypeus is less than half that of the facial space. 
The /egs are long and tolerably strong, of a dark reddish yellow- 
brown colour, furnished with hairs, bristles, and spines: the hairs 
and bristles appear to be most numerous underneath the tibie; but
