Salticus tenebricus, sp. n. Pl. xi., fig. 19. 
Length of an adult male 4 mm. 
The cephalothorax is brownish black, nearly glabrous; the thorax is 
rounded posteriorly and about one-third longer than the caput; the profile 
line rises with a moderately abrupt curve from the thoracic junction, then 
runs in a nearly even line, sloping slightly at the fore-part of the caput, 
which is prominent ; medial fovea moderately deep. The clypeus is directed 
inwardly, and in height hardly equals the diameter of one of the fore-lateral 
eyes. 
The lateral eyes nearly form a square, the transverse diameter being the 
greatest ; the intermediate laterals are equidistant between them. 
The legs are moderateiy long and stout, and do not differ much in their 
relative proportions, 1, 4, 2, 8; glossy brown, suffused with black, 
sparingly furnished with light hairs, spines moderately strong. 
The palpi are not very long, have a lighter shade than the legs, and are 
sparingly clothed with white hairs ; the cubital joint is rather stronger than 
the radial, the latter projects a large apophysis from its extremity, on the 
outer side; the digital joint is oval, convex and hairy externally, black ; 
beneath it is reddish-brown, prominent, projecting at the base in a con- 
vexity extending upwards to the articulation of the cubital and radial joints ; 
at the anterior extremity there is a small black corneous process directed 
outwards. 
The falces are broad, bowed outwardly in the centre, inclined inwardly ; 
they are rugulose, and have a bright reddish-brown colour. 
The mazille are straight, broad, rounded, bright brownish-yellow. 
The labium is broader than long, pointed, brown, yellowish apex. 
The sternum oval, brownish-black. 
The abdomen is oviform, shorter than the cephalothorax, blackish-brown, 
finely rugulose, sparingly clothed with whitish hairs.

- As there is no very satisfactory natural arrangement of this large 
family, I have thought it advisable for the present to follow the example 
of many arachnologists, including Blackwall, and to group all the species 
in the Latreillean genus Salticus, 
Fam. LYCOSIDA. 
Genus Sphasus, Walck. 
Sphasus gregarius, sp. n. Pl. xi., fig. 20.
