conical, armed with a few teeth on the inner surface, and somewhat inclined towards the 
sternum ; the maxillae are powerful, and inclined towards the lip, which is quadrate. These 
parts have a dark, reddish-brown tint. The sternum is heart-shaped, glossy, and of a brown 
colour, with very minute spots of a darker hue. The legs have a reddish-brown tint, and 
the anterior and posterior pairs are equal in length ; each tarsus is terminated by three claws ; 
the two superior ones are curved and pectinated, and the inferior one is inflected near its 
base. The palpi are of a red-brown colour, with the exception of the digital joint, which has 
a dark-brown tint; the humeral joint is curved towards the cephalo-thorax, and the cubital 
and radial joints are short, the latter having a large process, rounded at its extremity, on the 
outer and a smaller one on the inner side; the digital joint is oval, hairy and very convex 
externally, concave within, comprising the palpal organs, which are highly developed, com¬ 
plicated in structure, and of a red-brown hue. The abdomen is oviform, convex above, pro¬ 
jecting over the base of the cephalo-thorax; it is thinly clothed with hairs, and of a yellowish- 
brown colour, with numerous minute spots and fine streaks of a deeper shade, and the 
branchial opercula have a pale-yellow tint. 
Males of Neriene pulla, in a state of maturity, were captured in June, 1836, on rails near
