42 PROCEEDINGS OF THE CALIFORNIA 



* 



(dried specimens) a bright vermillion red throughout, except the fingers, 

 which are brown. 



Length, 0.50; width, 0.70. 



The specimens are from La Paz, Lower California, and were collecUd and 

 presented by Dr. D. E. Hungerford. 



Xantho multidentatus. * 



Areolets of anterior part of carapax distinct. 1 M confluent with 2 M, which 

 is partially cleft by a furrow; all the antero- lateral areolets (1, 2, 3, 4. 5, 6 L) 

 distinct; also, the postero-lateral (i, 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, N and S triple. The upper margin of the eye is enclosed in a semi- 

 circle 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. Edwards. 



Acteodes Mexicanus. 



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. The sulcus between the gastric and cardiac is well-defined, 

 and mo'st 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, w ak, 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, inclining 

 to red on the under side of the chelipeds. Fingers dark brown. 



As the fingers of the smaller hand are distinctly spoon-shaped, I have called 

 this an Acteodes, but it is evidently a connecting link between that genus and 

 Actcea.
