short, the latter having a large apophysis at its anterior extremity, which 
tapers to a bifid termination curved in front of the fifth joint, a strong 
obtuse process occurring within the curve, near its base; fifth joint oval, 
convex and hairy externally, concave within, comprising the palpal or 
sexual organs, which are highly developed, complicated in structure, 
with a prominent, obtuse, corneous process near their extremity, and a 
curved, pointed spine, directed outwards, extending nearly to the ter- 
mination of the joint; their colour is very dark brown. 
This species usually occupies an oval cell of compact, white silk, which it 
spins on the inferior surface of leaves and of liverwort growing on trees in the 
wooded districts of Denbighshire and Caernarvonshire. It leaps with agility.

Cephalo-thorax oval, convex above, thinly covered with hairs, glossy, with a 
narrow indentation in the medial line of the posterior region; anterior 
part reddish brown; sides and posterior part greenish brown, with a fine,
