CORINNA. 73 
Sternum and mouth-parts pale piceous, smooth. Coxe and trochanters of legs dull orange, smooth. 
Femur i. dark piceous, granulose on the outside area in front. Femur ii. paler piceous, shading to bright 
orange towards the base. Femora iii. and iv. paler orange, with the apical half annulate with piceous. Legs 
i. and ii. deep piceous-brown, shining ; tibie iii. and iv. orange, with piceous basal annulation, extending 
over half the segment. Protarsi iii. and iv. piceous, tarsi paler. Abdomen dull olive-brown, almost 
glabrous, with two large, dull white, irregular oval blotches situate just in front of the middle of the 
dorsal area. 
Carapace very broad in front, only one-quarter narrower than thoracic area. Caput gibbous, precipitous behind 
(not convex at the central fovea), closely rugulose-impunctate. Eyes widely separate. Posterior row 
procurved, eyes subequal ; centrals two and a half diameters apart, three and a half from laterals. Anterior 
row procurved ; centrals larger, just over half a diameter from central posteriors, the same distance from 
each other, and one and a half diameters from laterals. Anterior laterals smaller than posterior laterals, 
both situate on a common tubercle. Lower margin of fang-groove with four teeth. Sternum smooth, 
distinctly longer than broad; labium less than half the length of the maxille, the latter long, straight, 
concave on the outer side, enlarged at the apex. Trochanter of palp attached considerably behind the 
middle of the coxa. 
Legs clothed with numerous, semi-erect, fine, scattered sete. Tarsi and apex of protarsi of all four pairs 
scopulate. Tibia i. outside with five, inside with six spines, including a small apical pair. Tibia ii. 
with a single outer row of five spines, including the small apical spine. Protarsi i. and ii. with three 
pairs of spines and a single central apical spine. Protarsi iii. and iv. with a short brush of scopuliform 
hairs at the apex. 
Vulva very simple, consisting of a convex chitinous area, with a small circular fovea in the centre, close to the 
posterior margin. In some specimens this fovea has a minute convexity at the bottom. 
Hab. Guaremaa, near the Mexican boundary, Muxbal (Sarg). 
This spider is very similar to C. annulipes (Tacz.), according to M. Simon’s identifi- 
cation and description in Ann. Soc. Ent. Belg. 1896, p. 420, but there are probably 
numbers of species with the legs similarly coloured.

2. Carapace and mandibles dull black, rugulose or granulose-impunctate. Sternum pale mahogany-brown, 
granulose. Legs deep orange-brown, not granulose, femora very slightly so. Abdomen unicolorous 
olive-brown, paler beneath, with a single small, though conspicuous, dull white semilunular dot 
immediately above the spinners. 
Structure similar to that of C. variegata, but the anterior row of eyes is straight, not procurved, and the 
maxilla are much shorter in proportion to the labium. Tibia i. with five pair of spines beneath, one 
pair being apical. Tibia il. with four spines on the outer side and two on the inner side at the 
apex. Protarsi i. and ii. with three pairs of spines beneath and a small, single, central apical spine.
