CALIFORNIA STALK-EYED CRUSTACEA. 25 



Carapace ovate, tuberculated; median region tumid and furnished with 

 four tubercles, the three anterior of which are nearly abreast (the anterior 

 one a little in advance of the others); two double rows of curved setas in 

 front of the lateral tubercles, and two similar rows on the rostrum. Car- 

 diac and intestinal regions each furnished with a tubercle; two tubercles 

 on the branchial region, the one situated before the other. Rostrum prom- 

 inent, the horns divaricate and convex above, the triangular notch between 

 them hairy. Supraorbital tooth acute and directed forward, outward and 

 upward. Postorbital tooth acute and triangular. Behind the postorbital 

 there is a large, rather slender tooth which projects laterally, the tip 

 curving forwards. At the postero-lateral angle of the carapax there is a 

 prominent, pointed tubercle, in front of which the margin is furnished 

 with curved setae. A spine on the sub-branchial region below the middle 

 of the space between the postero-lateral tubercle and the large, curved 

 tooth. Pterygostomian region with three to six small teeth. Surface of 

 the ischium of the maxillipeds plane, but sometimes bearing a trace of a 

 longitudinal groove; exognath not grooved. Chelipeds large in the adult 

 males, much shorter and more slender in the females; the merus bears a 

 few tubercles on the upper side but no carina; the inner side may become 

 strongly ridged in adult males, but it is generally rounded in young males 

 and females; the carpus has two or three cristfe which become more prom- 

 inent in old males; hands compressed, the upper edge acute; fingers 

 shorter than the palm, and gaping at the base in old males. Legs sub- 

 cy^lindrical and crossed b}^ light-colored bands; merus and propodus not 

 crested. Color reddish. 



Length lj"g^ in., width across gastric region between tips of horns if in.; 

 across cardiac region l^-V in.
