Bugaba (Champion).—SovutH AMERICA. 
If this species be really identical with Salticus nigrolimbatus, O. P.-Cambr., and the 
others quoted by Peckham, then it is (as he remarks) truly cosmopolitan, for he quotes 
M. melanognatha as occurring also in Europe, Africa, the Canary Is., and the Malay 
Archipelago. 
2. Marpissa familiaris. (Tab. XXII. figg. 1, ¢; 2, 24a, 2.)

Hab. Nortu America ! 2,—Mexico, Minatitlan 3. 
Our figures of this species are taken from Peckham’s work.

Type, , in coll. Peckham: total length 12 millim. Deuterotype, d, in coll. Godman & Salvin: total 
length 10 millim. 
Hab. Mexico, Teapa (H. H. Smith); Guatemata (Sarg).—Amazons, Santarem !. 
The male, which is here described and figured for the first time, resembles the 
female.in coloration. An immature specimen of the former has a jet-black band down 
the ventral area, but it is almost obliterated in the adult male and female, perhaps 
owing to the action of the alcohol. 
4, Marpissa minor, sp.n. (Tab. XXII. figg. 5,5a,3; 6, 2.) 
Type ¢, gynetype @, in coll. Godman & Salvin. Total length, ¢ 7, 2 10 millim. 
Colour very similar in the two sexes. Carapace black or red-brown, with a fine white marginal line, and a 
broad central band of white hairs extending from the anterior eyes to the posterior margin, where it 
becomes gradually narrower. Abdomen with a broad lateral dorsal brown band extending from the 
anterior margin to the spinners, leaving a broad central pale band, more or less scalloped or indentate, on 
the sides of the apical half, the indentations being of a deeper black, as also are the outer margins of the 
lateral brown bands ; lower lateral and ventral areas white. 
Legs yellow, i. and ii. darker and more or less blotched with brown; iii. and iv. with a dusky spot at the apex
