1. Neriene longispina, sp. n. (Tab, XXXIX. figg. 9, 94a, b, os; 10, 
10 a, 2.) 
Type ¢, gynetype 2, in coll. Godman & Salvin. Total length, g 2, 55 millim. 
Female. Carapace red-brown, broadly margined with dusky brown, with a fine central, longitudinal, dark line, 
dilate behind the eyes. Sternum black. Abdomen black dorsally, with a central, leaf-like, whity-brown 
pattern, deeply dentate posteriorly ; lateral line almost entirely surrounded by a narrow white band, 
which is broken, however, in front and more broadly so behind, its posterior half on each side broken up 
into separate spots; ventral area dull black, with a faint dull white line on each side, extending from 
the spiracles almost to the spinners. Legs pale orange-yellow. Femora i. and ii. with two fine spines 
dorsally about the middle. Tibia and protarsi with dorsal, lateral, and ventral fine spines. 
The male is more elongate and brighter in colour than the female. The central posterior eyes in both sexes 
are larger than the laterals and seated upon conspicuous black tubercles. The patella of the male- 
palpus has no apical cusp or spur. The mandibles and mouth-parts in both sexes are dull black.

2. Neriene duplicata, sp.n. (Tab. XX XIX. figg. 11, 11 a, ¢.) 
Type, d, in coll. Godman & Salvin, Total length 5 millim. 
This species is similar in general pattern and colours to NV. longispina, but the carapace has no marginal nor 
central dark band, the sternum, mandibles, and mouth-parts are red-brown, and the legs are pale yellow. 
For the characters furnished by the palpal orgaus, see Plate and Table.

3. Neriene simplicata, sp.n. (lab. XX XIX. figg. 12, 12a, 3.) 
Type, d, in coll. Godman & Salvin. Total length 5 millim, 
Carapace, legs, and mandibles pale orange, without central or marginal dark bands; sternum dusky brown ; 
abdominal pattern and white lateral bar much more indistinct than in N. longispina. 
For more minute 
differential characters, see Table and Plate.

4. Neriene trifalcata, sp.n. (Tab. XXXIX. figg. 13, 13a, b, ¢.) 
Type, ¢, in coll. Godman & Salvin. Total length 5:5 millim. 
General characters similar to those of NV. lonyispina, but the mandibles, mouth-parts, and sternum are paler 
aud the carapace has no marginal nor central dark bands, though there is a tendency towards a. bruad 
dusky marginal suffusion in some examples. For other differential characters, see Table and Plate.
