414 ARANEIDEA. 
6. Abdomen angular ; central posterior eyes much further from 
each other (one and a half diameters apart, one-third from 
the laterals) . . . - 
Ree ee ere Erzrrotryrus, O. P.-Cambr. 
B. Legs relatively much longer. Eyes more widely separated . . Wenpincarpa, Keyserl. 
THERIDIOSOMA.. 
Theridiosoma, O. P.-Cambridge, Ann. & Mag. Nat. Hist. (5) iv. p. 193 (1879). 
Type 7. gemmosum (L. Koch). Europe. 
The type-species is much smaller than that of Wendilgarda ; the legs are relatively shorter and the eyes more 
closely grouped. The abdomen is globular. The central posterior eyes are slightly larger than the 
laterals, and a little closer together, being one-fourth of a diameter apart and one-third of a diameter 
from the laterals. The colulus is present, and the posterior and central pairs of spinners are situated in 
the same transverse straight line. The supernumerary claws, so called, are quite distinct in members of 
this genus. 
The two species occurring in the collection may be separated thus :— 
Females. 
a. Abdomen unicolorous dull orange. Posterior margin of vulva with 
a shallower -shaped indentation in the middle. . . . . . . concolor, Keys. 
6. Abdomen spotted with silver and black. Posterior margin of vulva 
more deeply indentate in the middle. . . - . + . + + + « globosum, O. P.-Cambr. 
1. Theridiosoma concolor. 
Theridiosoma concolor, Keyserl. Spinn. Amer. ii. p. 219, t. 10. figg. 183, 183 a—-c (9). 
Type, 2, in coll. E. Simon. Total length 4 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith)—Sourn America, Pebas, Amazons’. 
One cannot be quite certain, in the absence of the type, whether the examples before 
me are really identical with 7. concolor, but it seems probable. 
2. Theridiosoma globosum. 
Andrasta globosa, O. P.-Cambr. Biol. Centr.-Amer., Arachn. Aran. i. p. 192, t. 24. figg. 5, 
5a-f (3), 6, 64,5 (2)’. 
Type ¢, gynetype Q, in coll. Godman & Salvin. Total length, ¢ 2, 9 2°5 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
This species may be identical with 7. argentatuwm, Keyserl., described from an 
immature male; but even with the type before me it would be difficult to decide. 
EPEIROTYPUS. 
Epeirotypus, O. P.-Cambridge, Biol. Centr.-Amer., Arachn, Aran. i. p. 134 (1894). 
Type Z. brevipes, O. P.-Cambr. Central America. 
The type-species differs from that of both Theridiosoma and Wendilgarda in having an angular abdomen, and
