apart ee ee a ee 
2. Orifices larger and much closer together, about one diameter apart . similis, sp. 0. 
B. Lower margin of fang-groove with 3—4 teeth (the first tooth, when four are 
present, being usually very minute). Leg iii. with an anterior marginal 
row of small tubercles on the femur, patella, tibia, and protarsus, or on 
one or other of these segments. Sternum distinctly produced behind and 
squarely truncate. Orifices of oviducts very small, close together in the 
centre of a large shallow concavity. Posterior pair of spermathece very 
small, piriform; anterior pair much larger, piriform, and inclined over the

This species is obviously very closely allied to 7. ruber, Keys., and, according to 
Banks, 7. tranquillus (Hentz). The figure given by Banks, of the vulva, on tab. xiii. 
fig. 27, is not sufficiently detailed to enable one to separate 7. mexicanus from T. ruber, 
Keys., or 7. lanceolatus, F. Cambr. If the specimen is adult, the fact stated by Banks, 
‘‘legs with fine hairs, no spines,” might prove it distinct from either, for, except in 
immature examples, the first two pairs of legs in 7’. lanceolatus are always more or less 
cuspulate, while the type of 7. ruder, Keys., also presents this same characteristic. 
Banks does not mention the number of teeth on the fang-groove, and the value of the 
relative position of the eyes is considerably discounted by individual variation. Possibly 
he has carefully compared the Mexican form with examples from Massachusetts, 
whence the type of 7. ruber, Keys., hails. If so, his decision that the former is 
distinct from it is valuable, but neither his description nor figure unfortunately will 
enable others to benefit by this conclusion.

3d 2. Carapace and mandibles deep black-mahogany-brown. Legs dark orange-brown, the second pair paler. 
Abdomen dull clay-yellow, in the male with a rosy scutulate dorsal area. The four muscular scars 
noticeable in this genus are also present, as in other species. Sternum and mouth-parts very much paler 
than the carapace, mahogany-brown. 
_g. Carapace and mandibles rugulose-impunctate, less strongly on the cephalic area. Posterior row of eyes 
strongly recurved, centrals one and a half diameters apart, two from laterals. Anterior row procurved, 
centrals three-fourths of a diameter apart, three-fourths from laterals 3 eyes subequal. Clypeus less than

from beneath. Lower margin of fang-groove with two teeth, upper with three teeth. Sternum about
