96 PROCEEDINGS OF THE CALIFORNIA 



thought it singular that on a second visit paid to the spot in July, I could not 

 lind a single female, though at low tide mark I secured an overgrown male 

 who had lost too many limbs to retreat with sufficient quickness. 



Cancer aniennarius . Stimpson. Proc. Cal. Acad. Sci., I, 88; Crust, and 

 Ech., Pac. S. N. A., 22. 



No. 29. Female, dried. Probably from San Francisco Bay. Wm. Stimp- 

 son^?) 



No. 39. Young, between tides. San Diego. Hemphill. 



No. 41. Female, with ova. S. F. Bay. W. N. Lockington. 



This species appears to frequent deeper water than 0. productus or C. magis- 

 ter, as, though occasionally taken on the lines of the anglers in San Fran- 

 cisco bay, I have never known of its occurrence on the beach between tides. 

 It is found on the ocean shore near Tomales, and occurs as far south as Mag- 

 dalena Bay, Lower California, where a fine specimen was obtaiued by Mr. 

 W. J. Fisher. 



The sides of the chelipeds are beautifully marbled with dark spots upon a 

 lighter ground in adult recent specimens. 



Sub-Family Xanthine. 



Until very lately not a single representative of this sub-family had been 

 found upon our western shores, probably because the the first collections 

 were made in the neighborhood of San Francisco. 



The species named by Stimpson and Dana were collected at various locali- 

 ties from Monterey northward to Sitka, but the coast southward from the 

 former place to Cape St. Lucas, and the shores of the Gulf of California, 

 have been, and still are, comparatively unknown to carcinologists. 



All the species of Xantlunce. described or mentioned in these notes have 

 been collected in the last mentioned localities by Mr. Hy. Hemphill and Mr. 

 W. J. Fisher. 



Those species which I have previously described from single specimens 

 furnished to the Academy by the former collector are most of them more 

 fully known to me by numerous specimens obtained by the latter during five 

 months spent in dredging and collecting along the uninviting shores of Lower 

 California, while those which are new are in every case the results of the same 

 indefatigable collector's labors. 



It is somev hat singular that, so far as I am aware, not a single species of 

 this sub-family has yet been found along the shores of Northern California, 

 Oregon, or Washington Territory, and I cannot avoid thinking that further 

 search may disclose some. 



The genus Panopceus is represented on the shores of Central America by 

 two or three forms which have not hitherto been found so far north as Lower 

 California. 



I own myself unable to perceive any sufficient reason for the separation of 

 Xantho from Xanthodes, but I have relegated two of the narrowest forms to 

 the latter group.
