CALIFORNIA STALK-EYED CRUSTACEA. 121 



Eye-peduucles hispid and retractile against the anterior margin of the 

 carapace. Antennules large. Antennae shorter than the carapace; first 

 basal joint with a spine on either side; second joint produced into a long 

 acnte process whose outer margin is armed with four or five spines; acicle 

 narrow, acuminate, armed externally with numerous spines and about 

 equaling the lower spiny process. Ischium of the maxillipeds with two 

 small, subconical teeth on the outer surface near the antero-internal angle; 

 merus hispid, not dilated, and longer than the ischium; last joint of the 

 palp flattened below. Chelipeds unequal, very spiny; two or three very 

 large spines on the anterior margin of the merus and carpus; in the 

 larger hand the palm is inflated, the fingers deflexed, shorter than the 

 palm, excavated within, corneous tipped, and furnished with calcareous, 

 molar-like teeth. In the smaller hand the palm is not so strongly inflated, 

 the fingers are longer and straighter and more deeply excavated within; 

 the corneous tips are more extensive and the calcareous teeth are smaller 

 and more numerous. Ambulatory legs spiny, somewhat compressed; 

 dactyls about two-thirds the length of the propodi. Abdomen short, 

 broad, and soft, the spines not so large as on the carapace; on the basal 

 segment there is a median plate and two wide lateral ones; the plate on 

 the penultimate segment is oblong; the last one is small, rounded, and 

 about as long as wide. 

 Length of carapace from tip of rostrum, 58 mm.; width of carapace, 56 mm. 



Monterey (Stimpson)! Vancouver's Is. (Whiteaves); 

 ''California"! 



A rare species. Stimpson's description was drawn 

 from a small female which was somewhat broader than 

 long, .85 in. by .9 in. Our description is taken from a 

 single male from Monterey collected by Dr. Kitter. 



Genus Phyllolithodes Brandt. 



Carapace triangular, and provided with rounded tubercles which sur- 

 round an excavated area on the dorsal surface; lateral margins armed with 

 spines. Rostrum prominent, ending in two cornua. Acicle of the an- 

 tennae cut into prominent lobes. Chelipeds unequal, spinose. Ambula- 

 tory legs subcylindrical and armed with spines. Abdomen furnished with 

 calcareous plates in which is a central membranous area.
