Of the sixteen species of Spiders described on the present occa- 
sion, two are from Caffraria, sent to me by Mr. Mansel Weale ; 
one: from Sé. Helena, received from Mr. Melliss some years ago ; 
two from Ceylon, contained in the fine collection made for me by 
Mr. G. H. K. Thwaites ; and the rest (11 species) from a collection 
made on the Amazons by Professor Traill. All are, so far as I am 
able to ascertain, new to science, excepting the Spider from St. 
Helena, erroneously included by myself (P. Z. S. 1869, p. 538, pl. 
xlii. fig. 6) in the genus Olios. The example from which the 
description and figures (/. c.) were made was a very misleading 
one, having been pinned and dried, some important generic parts 
injured, and its legs extended laterally, in what I find since to be a 
quite unnatural position. Specimens of this Spider received more 
recently have convinced me that a new genus of Drasside must be 
established for its reception. Eight other new genera are also here 
characterized, belonging to the families Drasside, T, heridiide, Pol- 
tide, and Salticide. 
One other point of interest only need be noted here; and that is 
the discovery, for the first time in South America, of a species of the 
curious four-eyed genus Miagrammopes, Cambr. (posted, p- 435. 
The genus was. first characterized from Ceylon (Linn. Soc. Journ. 
x. p. 398). Since then it has been found at Sydney, N.S. W., 
Rodriguez, Zanzibar, and now also (2 species) in Caffraria (posted, 
pp. 436, 437). 
Fam. Drassipa@, 
XEROPIGO, g.n. (nom. propr.). 
Cephalothorax broad-oval, truncated in front. The lateral mar- 
ginal constrictions are strong ; and the profile-line forms a tolerably 
even curve from the upper part of the clypeus to the posterior 
margin, with a slight dip or depression at the thoracic junction. 
The height of the clypeus is rather less than half that of the facial 
space. 
Eyes 8, in two curved rows, the convexity of the curve directed 
backwards ; the anterior row shortest; they are of moderate size ; 
those of the fore central pair considerably the largest of the eight. 
Legs moderately long, not differing greatly in length, but strong, 
4,1, 2,3. They are furnished with hairs, bristles, and spines ; 
those beneath the tibiee and metatarsi of the first and second pairs 
are disposed in two longitudinal parallel rows, but irregularly dis- 
posed on the third and fourth pairs. Beneath the tarsi of the first
