aeronautic spider by the frequency of its aerial excursions.

Length of the male, ^th of an inch; length of the cephalo-thorax, T 5 th, breadth, a th ; 
breadth of the abdomen, ^th; length of an anterior leg, ith; length of a leg of the third 
pair, gth. 
The cephalo-thorax is oval, convex, glossy, rather prominent before, and has an indenta¬ 
tion in the medial line ; it is of a pale-brown colour, with narrow, dark-brown lateral margins. 
The falces are powerful, subconical, convex near the base, armed with teeth on the inner 
surface, and a pointed, conical protuberance in front, nearer to the extremity than the base, 
they are of a red-brown colour, and are inclined towards the sternum, which is broad, heart- 
shaped, and of a dark-brown hue. The maxillae are convex at the base, and provided with a 
conical process near the extremity, on the outer side; they have a red-brown tint, and are 
strongly inclined towards the lip, which is short, somewhat quadrate, and of a dark-brown 
hue. The legs are of a yellowish-brown colour, tinged with red, particularly the femora, and 
the anterior and posterior pairs are equal in length; each tarsus is terminated by three claws ; 
the two superior ones are curved and minutely pectinated, and the inferior one is inflected 
near its base. The palpi resemble the legs in colour; the cubital joint is clavate, and has a 
prominent, conical, pointed apophysis at its extremity, on the under side; the radial is stionger 
than the cubital joint, and is terminated by three apophyses ; two, which are large and obtuse, 
project over the base of the digital joint, and the other, which is small and pointed, is 
situated underneath ; the digital joint is oval, convex and hairy externally, concave within, 
comprising the palpal organs, which are moderately developed, complicated in structure, wit 
a strong, prominent process on the outer side, a smaller and darker one at the extremity, and 
are of a reddish-brown colour. The lateral eyes are rather the largest, and the anterior ones 
of the four forming the trapezoid are the smallest of the eight. The abdomen is ovi orm, 
convex above, projecting over the base of the cephalo-thorax ; it is thinly clothed with hairs, 
and of a black hue. 
According to M. Koch, the female is rather larger and lighter-coloured than the male. 
An adult male of this spider, which has the essential characters of a Neriene , was taken 
among herbage in a field at Southgate in May, 1850, and is in Mr.AValker’s cabinet.
