100 PROCEEDINGS OF THE CALIFORNIA 



No. 33. Monteivy. Dried. J. G. Cooper. 



Xantho Hemphillictna. Lockington, Proc. Cal. Acad. Sci., Feb. 7th, 1876. 



The only specimen I have seen of this species is the one in the possession 

 of the Academy of Sciences, San Francisco. Some small crabs from the 

 Gulf of California, which I at first believed to be young specimens of this 

 form, differ in their less transverse form and more perfect areolation, and I 

 now think them distinct, yet this can only be proved by the examination of 

 a complete series of the Monterey form. 



No. 35. Large male, dried. Monterey. Hy. Hemphill. 



Xanthodes leucomanus. Lockington, Proc. Cal. Acad. Sci., Feb. 7th, 1876. 



Carapax rather narrow; areolation very distinct, cardiac region circum- 

 scribed; three antero-lateral teeth (the three posterior ones) usually distinct, 

 and directed laterally, the space usually occupied by the first two antero-lat- 

 eral teeth forming an almost straight line. Basal joint of outer antennas 

 reaching the front; lower margin of orbit two-lobed; inner hiatus wide; front 

 sinuate, a process meeting the basal joint of the external antennas. Internal 

 antennas stout. Chelipeds sub-equal, manus broadly ovate, stouter than the 

 carpus, smooth, shining, with a slightly raised upper edge; dactylus and pol- 

 lex alike, short and stout, conical, toothed inside; furrowed. Carpus often 

 with a roughened upper surface. Ambulatory feet almost free from seta?, but 

 the dactyli thickly covered with very short tomentosity.

Numerous specimens of this species were brought from La Paz, Port Es-^ 

 condido and Mulege Bay, Gulf of California, by W. J. Fisher. They show 

 great variation in color, areolation, and other characters. In some the poste- 

 rior portion of the carapax is much less distinctly areolated than in others; 

 many individuals have the upper surface of the carpus, and even that of the 

 manas, more or less rugose; some have black fingers with white tips, others 

 have colored fingers, and the general tint of the carapax varies considerably. 

 The original specimens from which my pr- vious short description of this spe- 

 cies was written, were lost in removing our collection, and I cannot, there- 

 fore, feel certain of the identity of the Gidf form with the one first described. 



Xanthodes? angustus. nov. sp. 



Carapax narrow, front wide, slightly sinuate; antero-lateral margin shorter 

 than postero-lateral, three-toothed; teeth pointed forwards; the posterior 

 margin of the hindermost teeth in a line with the postero-lateral margin. 

 Upper margin of the orbit two-lobed, excluding the post-orbital, which is lower 

 than the two succeeding antero-lateral teeth. Upper surface of the carapax 

 smooth, shining, without areolation, except in the frontal region, and near the 

 antero-lateral teeth. Chelipeds smooth, shining, without areolation, hairs or 

 tubercles, hands rather broad, equal in size, fingers of right hand tuberculate
