the orbit. Ocular peduncles broad, eyes small. Superior margin 

 of orbit concave. External antennae one and a half times as 

 long as the carapax, flagella with few setae, some of which are 

 twice as long as the width of the flagellum. Anterior feet large, 

 broad ; margins smooth ; carpus conspicuously granulated above, 

 and scabrous on its infero-exterior surface ; pincers smooth, with 

 uncinate extremities. Second, third, and fourth pairs of feet with 

 tufts of hairs on the fifth joints and tarsi. Color dark purplish- 

 red. Length of carapax, 0.8 inch. Its affinities are with P. 

 valida, violacea, and granulosa. It is very common among the 

 rocks of the Californian coast. 



Eupagurus Samuelis. Front acute at the middle. Outer 

 antenna? articulated at the extreme antero-exterior corners of the 

 carapax ; extremity of terminal article of peduncle reaching 

 much beyond the eyes. Anterior feet differing much in size, the 

 right being much the longer and stouter ; carpus and hand gran- 

 ulated ; larger hand nearly twice as long as broad ; finger less 

 than half as long as the hand, with a slight crest not conspic- 

 uously denticulated. Feet of the second and third pairs very 

 slender, somewhat hairy ; the right foot of the second pair longer 

 than that of the first. Length, 0.75 inch. Taken at Tomales 

 Bay, by Mr. Samuels. 



EurAGUitus turgidus. Carapax rough, somewhat hairy ; 

 front broad, acute at the middle and on each side between the 

 bases of the eye-peduncles and the outer antennae. Antennae 

 very hairy, inner ones three fourths as long as the outer ones, 

 which are shorter than the carapax ; eyes reaching the extremity 

 of the peduncle of the outer antennae. Anterior feet equal, much 

 shorter than those of the second pair ; covered above with short 

 spines and tufts of long hair; hands short and very thick, strongly 

 tumid below ; finger about half as long as the hand. Feet of 

 second and third pairs nearly equal, spinulose and very hairy 

 throughout their length. Tarsi with corneous tips. Length, 

 three inches. Differs from the other Oregon species by the 

 hairiness of its tarsi. Taken in Puget Sound, by Dr. Suckley. 



Callianassa longimana. This species is closely allied to 

 C. Calif orniensis, Dana, but is larger, more slender, the outer
