CALIFORNIA STALK-EYED CRUSTACEA. 137 



on the upper surface of the dactyl, which is represented only by an 

 obtuse ridge in the preceding species. On the dactyl of .the smaller hand 

 there is an oblique, smooth surface visible from above which is not found 

 in alaskensis, and the supero-external surface of the carpus of the smaller 

 cheliped is much more flattened and the outer edge of the hand more ele- 

 vated and more sharply spinose. The dactyls are similar in form to those 

 of alaskensis, but are easily distinguished by the deep sulci on the upper side 

 bounded by sharp, minutely spinulous edges.

Anterior portion of the carapace wider than long; the three projections 

 of the front about equally advanced. Ocular peduncles short and stout, 

 but little over one-half the length of the anterior portion of the carapace . 

 Eye-scales acute, with a prominent, subterminal tooth. Acicle slender, 

 flattened above, and extending far beyond the eyes. Chelipeds spiny, the 

 carpus of the larger one with the sides flat and sharply granulated, the 

 upper surface evenly rounded and spiny, with a row of longer spines along 

 the inner margin; hand oblong, evenly rounded above, and spiny like the 

 carpus; dactyl with a row of spines on the outer edge and another row 

 near the middle of the outer surface. Smaller cheliped reaching a little 

 beyond the base of the dactyl of the larger one; carpus and hand spiny 

 above, the inner edge of the palm somewhat raised and armed with two 

 rows of spines, the outer spines being the shorter. The meral, carpal, and 

 propodal joints of the ambulatory legs are spinous above; the dactyls are 

 spinous, twisted, grooved on each side, and nearly as long as the two 

 preceding joints. A large species.
