rather slender, from a third to more than half as long as the hind tibia?, the tip 
hardly upcurved and exceedingly acnte, the denticulations of the inner valves tri- 
angular, hardly aculeate.

Crescent City, Fla., in gopher burrows (H. G. Hubbard); Georgia 
(H. K, Morrison). — [Scudder] 
The following description of the pseudo-scorpion found in the gopher 
burrows has been kindly furnished by Mr. Nathan Banks. 
Chelanops affinis Banks, n. sp. 
Length 2 mm . Pale yellowish, legs aud abdomen whitish. Cephalothorax and 
abdomen with clavate hairs; those on palpi less clavate. Trochanters of palpi with 
globose projections above; femora slightly pedicellate, very little broader near base 
than at apex; tibiae moderately swollen on inner side, slightly broader than femur 
and nearly as long ; hand about as long as tibia and much broader, tapering to 
the fingers, the latter a trifle longer than hand, moderately curved. Abdomen quite 
broad, the segments indistinctly divided; legs more slender than usual. 
Closely related to Ch. pallidus Banks, differing principally in the more 
swollen tibia, more slender and more pilose band, and the longer legs.

To Dr. George Marx, of Washington, D. C, I am indebted for the 
following description of the tick found upon the Gopher. 
Amblyomnia tuberculatum Marx, n. sp. 
Female: very large, suborbicular; length of body 7.6 mm . ; length of capitulum 
3 mm . Capitulum dark reddish-brown with a pale testaceous , narrow transverse band 
behind the front margin which extends in the middle, between the two glandular 
depressions into a round spot. Palpi reddish-brown with the basal part of the 
second joint pale testaceous, rostrum pale testaceous, shield dark reddish-brown 
with silvery figurations ; abdomen of the same color, legs with narrow whitish tips 
of the joints. Underside: capitulum posterior region, reddish-brown, frontal one 
white, maxillae yellow testaceous ; palpi, first joint with a reddish-brown triangular 
sclerite; second joint with yellowish basal half and reddish-brown terminal half; 
third joint reddish-brown; coxae dark brown; body brownish-yellow. 
Capitulum longer than broad with rounded posterior and lateral margins without 
projecting postero-lateral angles, the glandular depressions oval, obliquely out- 
ward and deep. Palpi, first joint free, second joint with along basal part, itself 
short and triangular, not quite double as long as wide, drawn out at inner basal angle 
into a point which, however, forms no projection, but runs into a ridge down to the 
first joint, underside at distal end projecting over the third joint ; third joint as broad 
as long, basal margin with a sharp, short tubercular projection, maxillae long, attenu- 
ate in the middle and with the tips clavate ; armature, four rows of spinous plates on 
each side, occupying only one-fourth of the length, and the rest covered with flat, fish- 
scale-like plates which gradually diminish in size toward the base ; mandibles as 
long as palpi, sheath with a furrow in the middle. Shield finely punctured, clypeus 
flat, sulci comma-shaped, very deep, a shallow impression behind them; abdomen 
without punctures, with distinct lateral groove and posterior lobes and three dorsal 
longitudinal lines behind the shield ; underside, finely punctured, with short white 
hairs in the punctures; legs long and slender with sparse short white hairs; coxae I 
with a short, round tubercle on the antero-internal region; the four coxhs with two 
flat and sharp tubercles obliquely above the posterior margin; at coxae I the external
