Length of carapax 11.5 



Width of carapax 18 



A single specimen, female, from San Jose Island, Amortiguado Bay, Gulf 

 of California. In spirits the areolets are of a bright yellow color. There are 

 five tubercles on the carpus, and as many on the hand. The genera Actcea 

 and Adeodes are usually placed in separate sub-families, but the artificiality 

 of this separation is evident to any one who compares the species belonging 

 to the two genera. In this species, as in A. spedosa and A. cavipes, Dana, 

 and A. mexicanus (mihi), the tips of the fingers are but imperfectly excavate, 

 and the forms belong as truly to Adcea as to Adceodes. The two genera form, 

 in fact, a continuous series of closely allied species. 



Chlorodius Fisheri. nov. sp. 



Similar in proportions to C. sanguineus, Edwds, but the carapax is widest 

 between the posterior teeth of the antero-lateral maigin. Front 4-lobed; a 

 deep emargination between the long central lobes. Teeth of antero-lateral 

 margin five in number, acute, sub-equal, and directed forwards Areolation 

 less distinct than in C. sanguineus; areolets well-defined anteriorly, but not 

 posteriorly. Pre-medial areolets joined to the extra-medial; intra-medial sep- 

 arated from the posterior or cardiac by a distinct sulcus; areolets of antero-late- 

 ral region six in number; postero-lateral and posterior regions without distinct 

 areolation. Chelipeds equal, smooth, except a tooth on inner angle of car- 

 pus; all the fingers spoon-shaped, but the cavity not circumscribed within. 

 The fingers are sulcated. Posterior legs slightly setose, claws sharp. 



Color. Carapax, greenish red; chelipeds, marbled with purplish red, white 

 beneath; fingers, black. Length of carapax of largest specimen (male), 0.78 

 in.; greatest width, 1.06 in. 



Numerous specimens from the West coast of Lower California, collected by 

 W. J. Fisher, also from La Paz, San Jose Island, Mulege Buy and Port Es- 

 condido, all in the gulf of California. It is found on the flats at low tide.
