342 ARANEIDEA. 
Females. 
A. Vulva consisting of a distinct raised chitinous convex tongue, its apex 
directed forward towards the base of the abdomen. 
1. Apex of chitinous tongue, seen from above, wedge-shaped, sharply 
pointed; seen in profile strongly geniculate and incurved under itself. gracilis. 
2. Apex of chitinous tongue, seen from above, dilate, semicircular, emar- 
ginate on each side ; seen in profile bent downward, but only very 
slightly incurved «2. 1. ee ew ee ee ew ww ee Lingulifer, sp. n. 
B. Vulva consisting of a more or less well-defined transverse-oval cavity. 
i. Clypeus and mandibles pale, without any narrow black lines in front 
running down the centre from the anterior central eyes. 
a. Clypeus much higher, nearly four times the width of the space occupied 
by the anterior central eyes. Chitinous margin of vulva widely . 
open anteriorly. . . 2. 2. 1 2 ee we ew we we ee ew ) Clypeatus, sp. 2. 
b. Clypeus much lower, scarcely more than twice the width of the space 
occupied by the anterior central eyes. Chitinous margin of vulva 
either closed or only with a narrow opening anteriorly. 
1. Cavity larger in proportion and the chitinous rim much narrower, 
closed anteriorly. Legs notannulate . . ... . . . . globosus. 
2. Cavity smaller in proportion and the chitinous rim much broader, with 
a narrow opening anteriorly. Legs annulated with dusky brown. annulipes, sp. n. 
ii. Clypeus and mandibles either entirely brown or with a narrow black 
line running down the centre from each anterior central eye. 
a'. Clypeus and mandibles pale, with a narrow black line.

the posterior portion at the genitalrima. . . . . . . . .. bifissus. 
6*, Vulval cavity closed in front, with a transverse chitinous margin 
posteriorly, but some distance in front of the genitalrima . . . transversus, sp. n. 
b!. Clypeus and mandibles, as well as the whole carapace, deep brown . drunneus, sp. n. 
Nore.—The coloration and markings would probably furnish very reliable distinguishing characters ; but in 
the examples under comparison so much of the scaly.covering of hairs has been rubbed off that it would not 
be safe to make use of them in these tables. 
I do not know either O. flavus or O. acutus, Banks, nor can I gather from his figures what are the 
differential characters.

Type ¢,gynetype 2, in coll. Keyserling, Mus. Brit. Total length, $ 5, 9 7 millim. 
d. Legs orange-yellow, the femora of all four pairs with a fine, often broken, narrow black line running 
down the outer side, but often entirely obliterate. Carapace orange-yellow, with two closely adjacent, 
longitudinal, central, and a more widely separate lateral band composed of brown scales. A narrow black 
line runs down the clypeus and anterior centre of the mandibles. Abdomen dark brown or black, with 
a well-defined dorsal band narrowly outlined with white anteriorly, thus enclosing a lanceolate black 
mark, the two white lines coalescing just behind the middle to form a narrow central line to the spinners ; 
ventral area dark brown, with a black central band. Sternum yellow; palpi dark brown.
