CLUBIONA. 169 
outer sides being rather longer than the anterior side. The height of the clypeus is about equal to half 
the diameter of the fore-central eyes. 
The Zegs are of moderate length and strength, 1, 4, 2,3, furnished thinly with hairs, and armed with some long 
and strongish spines. Beneath the tarsal claws is a claw-tuft, which is of a denser and more pad-like 
form on the third and fourth pairs. 
The palpi are moderately long, furnished with longish hairs and some slender bristles, and four spines (}) on 
the upperside, near the fore extremity of the humeral joint. ‘The radial joint is half as long again as the 
cubital, and furnished on the inner side with some strong, pale, bristly hairs ; it is of a curved form, and has 
at its anterior extremity on the outer side a long, strong, nearly straight apophysis, rather narrower in the 
middle than at the extremities, and nearly equal to the joint in length ; this apophysis ends in a strongly 
emarginate or furcate form ; the posterior limb of the fork is stronger than the anterior, and obtuse, the 
anterior being rather sharp-pointed. The digital joint is rather large, broadly truncate in form at its 
extremity, rather densely furnished with pale bristly hairs. The palpal organs are of great size, consisting 
chiefly of a large, flattish, somewhat circular, and on one side convex, prominent lobe, concave beneath, 
with a strong corneous process within the concavity ; the margin of this lobe is bounded by a closely- 
fitting, tapering, red-brown spine. 
The falces are tolerably long and of moderate strength, straight, but projecting forwards and slightly divergent 
towards their extremity ; they have, towards the base in front and on the sides, a few minute red-brown 
granulosities and bristly hairs—some also of the latter at their extremities, where there appear to be no 
teeth in opposition to the fang, which last is strong, slightly curved, and tapering. 
The mawille, labium, and sternum are normal. 
The abdomen is of a narrow, elongate-oval, somewhat cylindrical shape, clothed with coarse as well as pale 
silky hairs. The spinners are rather long, those of the superior pair longer than the inferior pair by the 
length of their second or terminal joint. 
The female is larger than the male, but similar in colour and other general characters, but the intervals between 
the eyes are greater. The genital aperture is large, of a characteristic somewhat quadrate form, and of a 
dark red-brown colour. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
Clubiona attigua, sp. n. 
Adult male, length 2% lines. 
Cephalothorax normal in form, colour dull orange-yellow, clothed thinly with whitish-pubescent hairs, the 
normal grooves a little darker. 
Eyes on black spots in two transverse rows, the posterior row straight, the anterior with its slight curve 
directed forwards ; the two forming an exact segment of a circle—those of the hinder row and the fore- 
laterals are subequal, but larger proportionately than in most of the European species of this genus, 
the fore-central pair being much the smallest, and separated by slightly less than a diameter’s interval, 
each being equally separated from the fore-lateral eye on its side. The eyes of the hinder row are 
equally separated from each other. Those of each lateral pair are near together, but not contiguous. 
The height of the clypeus is rather greater than the diameter of the fore-central eyes. 
Legs tolerably long, 1, 4, 2, 3—1, 4, and 2 being subequal, moderately strong, armed with longish spines and 
a few hairs. Terminal tarsal claws springing from a small claw-joint, and furnished with a strong 
compact claw-tuft. Colour orange-yellow. 
Falces long, strong, nearly straight, but divergent and projecting forwards, of an orange-yellow-brown hue, 
furnished in front with numerous bristly pale hairs; they are a little hollowed near their extremity on 
the inner side, near which and below the inner margin are several short strongish teeth, and strongly 
prominent underneath, with a transverse ridge armed with two teeth near the extremity of the maxille, 
and numerous long, strong, bent bristles directed inwards; also at the fore extremity on the inner side is 
a strong obtuse (rounded at the end) prominence, close to the insertion of the fang. 
Palpi moderate in length and strength, yellow, digital joint yellow-brown. The humeral joint has, towards 
its fore extremity above, three black spines, 1, 2; the cubital joint is scarcely half the length of the radial 
and has a black bristle directed forwards on the upperside from each extremity, the anterior one being
