spine, a blunt tooth beneath it, an anterior groove. Large hand strong,

 allel to proximal end of palm. Legs long and narrow, anterior margins 

 of merus finely spinulous; last two articles with pubescent margins.

MICROPANOPE AREOLATA Rathbun 



Plate 182, Figures 1 and 2 



Micropanope areolata Rathbun, Proc. U. S. Nat. Mus., vol. 21, 1898, p. 588 

 (type-locality, off Adair Bay, Gulf of California, 11 fathoms, station 3024, 

 Albatross; type, Cat. No. 21584, U.S.N. M.). 



Diagnosis. — Carpus of chelipeds and antero-lateral portions of 

 carapace rough. Color of immovable finger continued on palm. 

 Otherwise near nitida. 



Description. — Closely allied to M. nitida, with which it may be com- 

 pared. Carapace somewhat narrower, front relatively narrower, 

 first and second lateral teeth more completely united. Surface 

 sHghtly pubescent, regions more distinctly marked, granulation fine 

 but plain on protogastric, hepatic and epibranchial lobes, epigastric 

 ridge well developed. A subhepatic tubercle. Wrists much rough- 

 ened, palms finely rugose, color of immovable fingers extending well 

 back on palms, basal tooth of major dactyl not heavy, though larger 

 than in nitida. Male abdomen similar to that of M. nitida but last 

 two segments shorter. 



Measurements. — Male holotype, length of carapace 6.4, width of 

 same 8.9, fronto-orbital width 6.7, width of front 3.4 mm. 



Range. — Southern California and Gulf of California, to a depth of 

 11 fathoms. 



Material examined. — See table, page 449.

 for 1900, vol. 20, part 2 (1901), p. 35. 



Diagnosis. — Second lateral tooth absent. Palms rough with bead 

 tubercles, covering both palms of female and minor palm and greater 

 part of major palm of male. (
