ANYPHANA. 201 
Falces rather long, strong, a little tapering, and slightly divergent at the extremities. 
Palpi moderately long ; cubital joint rather clavate, with a long and strong spiny bristle at the fore extremity 
on the upperside, and two others less strong near the hinder extremity. Radial joint longer and stronger 
than the cubital, some long strong spiny bristles in front; at the fore extremity on the outer side is a 
strong prominent apophysis, somewhat constricted in the middle, wider at the extremity than at the base, 
of a somewhat flattened form, and truncated at the extremity, the upper corner being sharp, the lower 
one rounded; beneath this apophysis is another, more massive, but shorter and obtuse at the end, and 
springing from the same general prominence as the upper apophysis ; behind these, on the underside of 
the radial joint, are numerous long coarse pale hairs. The digital joint is of large size, and covered 
with long strong bristly hairs, some of the longest and strongest and of a pale colour being ranged along 
the outer margin of the joint; its length is equal to that of the humeral joint; at its base, rather 
on the outer side, is a strong subconical prominence. The palpal organs are highly developed, consisting 
of several strong corneous processes, of which one is of a tapering form, and extends forwards with its 
slightly bent point beneath the fore extremity of the joint.

The example from which the above description has been made was in too bad a 
state of preservation to enable any details to be given of some points of structure; in 
fact, the extra apparent size of the eyes may perhaps be owing to the partial separation 
of the epidermis and cornea of the eyes from the new cuticle and cornea forming 
underneath. ‘The form and structure, however, of the palpi, which are very striking, 
and had not suffered, will be sufficient fur the easy determination of the species. 
Anyphena gibba, sp. n. 
Adult male, length 23 to 3 lines. 
This spider is of normal form and general structure. 
Cephalothorax yellow-brown, with a fine black marginal line ; two well-defined longitudinal bands run back- 
wards on either side of the median line from the lateral eyes to the posterior extremity ; a fine deep red- 
brown central longitudinal line runs forwards from the thoracic indentation; on each side of the fore 
extremity of this line is a linear deep red-brown spot, and from near these on the inner side is a dusky 
yellow-brown short stripe running to the hind-central eyes. Height of clypeus rather greater than the 
diameter of the fore-central eyes. 
Eyes on black spot, general position normal. Central quadrangle almost equal in length and breadth, slightly 
longer than broad, but the fore side much the shortest. yes of posterior row equidistant from each 
other ; the fore-central pair much the smallest. 
Falces moderate in length and strength, similar to the cephalothorax in colour, with two dusky brown longi- 
tudinal lines in front of each, the inner one curved, the outer more nearly straight, the two enclosing an 
irregular oblong figure. Their inner sides towards the extremities are furnished with numerous strong 
bristly hairs. 
Legs rather long, 1, 4, 2,3. Spines normal, colour yellow, the femora, genue, and tibie thinly marked with 
minute dusky spots. 
Palpi similar to the legs in ground-colour ; the humeral joint has three short strongish spines in a transverse 
line near the fore extremity on the upperside, and a longer and stronger one about the middle of the 
joint; cubital joint moderately long, somewhat bent and clavate, with a strong spine-like tapering bristle 
in front at the fore end; radial joint slightly longer than the cubital, furnished with some strong spine- 
like bristles, and with a large obtuse prominence near the middle on the underside, and a large peculiarly- 
shaped apophysis at the extremity on the outer side, of a shining dark red-brown colour, and as long as 
the joint itself (figures only can give any satisfactory idea of its form); digital joint large, oval, equal 
in length to the radial and cubital joints together ; palpal organs highly developed, prominent and mode- 
rately complex in structure. 
Mazille, labium, and sternum yellow. 
Abdomen oval, pointed behind; ground-colour dull luteous-yellowish, on each side of the median line of the
