12 mètres. Comprised within each cocoon are about 20-32 pale stone- 
coloured unagglutinated eggs. In the first cocoon of a nidus examined on 
the 14th June the young were little more than 1 mm. in length, and had 
attained to some extent their normal tints; the abdomen was a broadish 
oval, convex, with only a slight longitudinal indentation on the fore-part, 
the tail being represented by a small convex lobe; in the second cocoon 
the tints were not so dark, and the young in the third had only a slight 
tinge on the abdomen; fig. 10, pl. x., respresents a young translucent 
spider from the fourth cocoon; the fifth and sixth only contained eggs. 
The female invariably rests in the centre of the web.

Arachnura obtusa, sp. n. 
Length of a mature female, 6 mm. 
This species may be distinguished from A. longicauda not only by its 
smaller size, but by the almost entire absence of the longitudinal cleft in the 
abdomen, and the more vertical position of the tubercles, which are obtuse, 
and of an orange-red colour with buff tips. The cephalothorax is of an 
olive-tinged yellow colour, suffused with chocolate-brown, medial band same 
hue. Legs and palpi yellowish-brown, suffused with chocolate and marked 
with a few olivaceous streaks. The falces have the yellowish hue of the 
legs, and the maville and lip are chocolate, with olive-yellow margins. The 
abdomen is of an olivaceous-brown colour mottled with a lighter tint ; the 
medial band is brown margined with orange-red; the tail is distinctly 
_ Wrinkled and has the same dark hue, its five small tubercles resemble the 
anterior ones in colour,
