(dried specimens) a bright vermillion red throughout, except the fingers, 
which are brown. 
Leneth, 0.50; width, 0.70. 
The specimens are from La Paz, Lower California, and were collected and 
presented by Dr. D. E. Hungerford. 
Xantho multidentatus. AMAA 
Areolets of anterior part of carapax distinct. 1M confiuent with 2M, which 
is partially cleft by a furrow; all the antero-lateral areolets (1, 2, 3, 4, 5, 6 L) 
distinct; also, the postero-lateral (1, 2 and 3 R) and posterior (1, 2 P) suf- 
ficiently distinct to be made out. 
The projecting lateral teeth are the normal ones, D being simple, E andT 
double, Nand S$ triple. The upper margin of the eye is enclosed in a semi- 
cirele of teeth, the outer of which is the first of the antero-lateral series. Two 
teeth intervene between the outer tooth and the front, which is four-toothed, 
and deeply emarginate in the centre. 
Upper parts of hand and carpus covered with sub-seriate tuberculations, 
Posterior feet short, compressed, cristate. 
The single dried specimen, a male, shows traces of a dark purple tint on 
the carapax and anterior feet. 
It was collected at Mazatlan, by Mr. Hy. Mdwards.

Acteodes Mexicanus. — \ mag ‘ore : CB, woe ermfs 
Carapax smooth, unarmed, transverse, wide, antero-lateral border forming, 
with the front, the greater part of an ellipse. Teeth of antero-lateral border 
reduced to slight curves. Front somewhat waved, and slightly projecting be- 
yond the general curve of the ellipse. 
Areolets indistinct throughout, yet the median can be distinguished from 
the antero-lateral. he sulcus between the gastric and cardiac is well-defined, 
and most of the sub-regions can be made out. Postero-lateral border only 
slightly concave, forming a very obtuse angle with the posterior border. 
Right cheliped the larger. entirely unarmed, smooth; fixed finger with two 
large tubercles on the inner face, dactylos with two large and two small tuber- 
cles; the fingers not spoon-shaped, gaping, and touching at the points only. 
Left cheliped smaller, and differing from the right in the fingers, which fit 
pretty closely throughout their length, tips spoon-shaped. 
Hinder limbs smooth, weak, slightly heavy in the last two joints. 
A single male specimen from Mazatlan, collected and presented by Mr. Hy. 
Edwards. 
Length, 0.56. Width, 0.80. 
The general color of the dried specimen is a dull reddish brown, melange 
to red on the under side of the chelipeds. Fingers dark brown 
As the fingers of the smaller hand are distinctly spoon-shaped, c have called 
this an Acteodes, but it is evidently a connecting link between that genus and
