2. Tibial spur very much broader, with a sharp small hook on the 
upper margin. Tibia about one-fourth longer than the patella. 
Terminal spine sinuous, directed forwards, but more or less 
across the palpal organs. . . soe ee we ew ew CUrvispina, sp. n. 
6. Tibial spur short, slender, sharp- pointed. Terminal spine making 
a circular sweep round the apex of the bulb and then directed 
sinuously forwards . . . 6. 1. 1 ee ee ew ew eee) placens, O. P.-Cambr. 
Females. 
The two species recorded of which the females are known can be best separated by comparing the 
figures of the vulva. 
1. Sillus putus, 
Anyphena puta, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. i. p. 200, t. 26. figg. 2, 
2a-c(¢?)’. 
Type, 2, in coll. Godman & Salvin. Total length 13-145 millim. 
Hab. Costa Rica (Sarg '). 
9, Sillus attiguus. (Tab. VII. figg. 27, 27a, 3.) 
Clubiona attigua, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. 1. p. 169, t. 21. figg. 1, 
la-e(3d)’. 
Type, d, in coll. Godman & Salvin. Total length 6 millim. 
$. Colour as in S. curvispina. Structure also similar, except in the palpus and mandibles. 
Palpus : tibia nearly twice as long as the patella, distinctly longer than the tarsus, narrowed towards its base 
Tibial apophysis directed outwards and downwards, coneave beneath, terminating in a minute curved 
point, but not a sharp spine (see figures). Mandibles enlarged, gibbous at the base beneath, bearing three 
small teeth on the lower margin of the fang-groove, and three (one single, one double tooth) on the anterior 
margin of the basal protuberance. The spine at the apex of the bulb is short, stout, strongly curved, but 
not sinuous. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith +); Guaremata (Sarg). 
8. Sillus lunula, sp. n. (Tab. VII. fig. 25, 2.) 
Type, 2, in coll, Godman & Salvin. Total length 7 millim. 
Q. Colour very similar to that usual amongst Anyphenine forms. Legs, carapace, mandibles, and sternum. 
pale orange-yellow. The carapace bears two brown bands on each side of the central line. The abdomen 
is dull yellow-white, with a brown speckled dorsal band, resolving itself into the usual series of oblique 
accent-like spots from the centre to the spiuners. The tibie and protarsi of legs iii. and iv. are annulated 
with dark brown at the apex. | 
Posterior row of eyes straight, subequal ; centrals slightly further apart, less than a diameter from each other, 
less than half from the laterals. Anterior row straight, centrals much smaller. Eyes equidistant, 
almost in contact. Maxille more or less purallel-sided, scarcely more than twice longer than broad. 
Tibix i. and ii. with 2—2 spines beneath, no apical pair ; 3 lateral spines and 2 dorsal. Protarsi i. and il. 
with 2—2 spines beneath and 3 lateral spines. Patelle i., ii, iii., iv. with a single slender apical and 
basal bristle. Scopula beneath protarsi and tarsi i. and ii. very slight.
