each other ; posterior centrals larger than posterior laterals. Clypeus over one diameter of an anterior 
central eye. Lower margin of fang-groove with three large and two small teeth. 
Vulva formed on the same plan as in C. fungifer &c. from the Eastern Archipelago. It consists of a broad 
transverse semilunar convexity, its concave side directed forward, having a stout tooth on each side 
posteriorly. 
Hab. Mexico, Soledad in Guerrero (H. H. Smith). 
Two adult females were taken by Mr. H. H. Smith at Soledad. C. excavatus is 
allied to C. bilobatus, having the irregular white lines beneath the abdomen, though 
probably without any dentate band on the dorsal area; but the straightness of the 
anterior row of eyes of the former will serve to separate the two, that of C. bilobatus 
being procurved. 
7. Ctenus spiralis, sp.n. (Tab. VIII. figg. 4, 44, 3.) 
Type, ¢, in coll. Godman & Salvin. 
¢. Total length 16 millim. Carap. 9x7. Pat.4tib.i. 14; iii, 10°55; iv. 14. Prot. i. 9°25; ini. 7; iv. 12. 
g. Carapace and legs mahogany-brown, probably clothed with grey pubescence; abdomen dark olive-brown, 
paler beneath. (The colour and pattern of the specimen are not well preserved, the pubescence having 
been to a very great extent rnbbed off.) 
Carapace slightly raised behind and bilobate. Tibial apophysis of palpus obtuse, with two distinct spurs 
springing from it, the smaller near the apex, the other towards the base above. Central lobe of palpus 
very long, much longer than broad, four or five times its breadth. 
Hab. Costa Rica (Rogers).

Hab. Panama}. 
Judging by the figure given in Keyserling’s paper of the protarsus of the last pair of 
legs, this species is certainly not identical with that whose protarsus is figured by 
M. Simon in Hist. Nat. Araign. éd. 2, ii. p. 107, fig. 100 (p). It rather resembles 
C. sinuatipes, F. P.-Cambr., but if correctly drawn it is quite distinct from this 
species too.
