202 ARANEIDEA. 
fore part above is a well-defined curved black-brown stripe, the convexity of the curves of each of the 
two stripes directed outwards, and following these is a series of rather strong well-defined, though almost 
contiguous, angular bars or chevrons, reaching to the spinners; on the sides of the abdomen are a few 
scattered small blackish spots, and a broken marginal line divides them from the underside, which has a 
central longitudinal dusky blackish stripe, from the spinners to the transverse spiracular opening ; near the 
middle the superior spinners are black. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (HZ. H. Smith). 
Anyphzna gibbosa, sp. n. 
Adult male, length 3 lines. 
This spider is very closely allied to A. gibba (p. 201), resembling it closely in size, colours, and markings, but 
the form of the radial joint of the palpus and the structure of the palpal organs present differences which 
serve to distinguish it with certainty. On a comparison of the figures given of each from the same point 
of view this is at once apparent. Some other minor points may, however, be noted: the eyes of the 
hind-central pair are a little further from each other than from the hind-laterals ; and the abdominal 
markings are rather more intensified and clear, and the sides are more thickly marked with short linear 
black spots. On the outer side (mostly rather behind the exinguinal joint) of the palpus is a closely-set 
group of short curved spines, against which it is possible that the coxe of the first pair of legs may 
work and produce stridulations. These spines exist also in A. gibba, though without removal of the 
palpus or legs it is not easy to observe them. Beneath each of the coxe of the legs of both this spider 
(male) and A. gibba is a group of short spine-like bristles; those on the third pair of legs surmount a 
strong subconical protuberance of the joint; those on the first pair would be well placed for traversing 
the group noted on the exinguinal joints of the palpi for the purpose of stridulating. Like A. gibba, 
the present species has a strong prominence beneath the radial joint of the palpus, but it is stronger than 
in A. gibba and nearer to the posterior end of the joint. 
Hab. Mexico, Amula in Guerrero (H. H. Smith). 
An adult female accompanied this spider, and very possibly may be of the same 
species, resembling the male in size, colours, and markings, while at the same time it 
may possibly be the female of some other very nearly allied form. The genital 
aperture, as usual, is of characteristic form. 
Anyphena subgibba, sp. n. 
Adult male, length rather over 1? lines. 
In general appearance, colours, markings, and structure this species is very similar and nearly allied both to 
A, gibba (p. 201) and A. gibbosa (supra). It is, however, smaller. The legs are almost unspotted. 
The central quadrangle of the eyes is as broad as long, if not slightly broader, and the interval between 
the hind-central pair is distinctly, though not much, greater than that between each and the hind-lateral 
eye next to it, being very nearly equal to a diameter. The height of the clypeus is equal to the diameter 
of a fore-central eye. 
The palpi, as in both the other species mentioned, have a strong protuberance beneath the radial joint, but it 
is nearer to the posterior extremity of the joint than in A. gibba, and less strong than in A. gibbosa, 
this joint and the cubital being scarcely different in length. The radial joint has also a long strong 
apophysis at its fore extremity on the outer side, of a bifid or furcate form, the posterior limb longest and 
strongest, the anterior rather bent and pointed; the palpal organs appear to be rather less complex than 
in A. gibba and A. gibbosa. The humeral joints of the palpi, like those of these two species, have each 
three spines in a transverse row at the fore extremity on the upperside, and another longer one a little 
way behind. The coxe of the third pair of legs are strongly protuberant, but not so conical as in the 
other species, All the coxe, excepting those of the fourth pair, are furnished with a group of short 
spines, as in A, gibba, &c.; the exinguinal joints of the palpi are also similarly furnished. 
Hab. GuatEMaa, between Petet and Chicoyoito (Sarg).
