PART 1 GARTH : PACIFIC OXYRHYNCHA 195 



Legs subcylindrical and crossed by light-colored bands; merus and 

 propodus not crested. (Holmes, modified) 



Material examined: A total of 274 specimens from 99 stations, di- 

 vided as follows: (See Table 34) 



Allan Hancock Foundation material: 237 specimens from 91 stations. 



Provincial Museum material : 2 specimens from one station. 



Hopkins Marine Station material : 35 specimens from 7 stations. 



From S. Bottle Island, Vancouver Island, British Columbia, to San 

 Geronimo Island, Lower California, Mexico. 



Measurements : Largest specimen, a male: length 40.6 mm, branchial 

 width 31.4 mm, hepatic width 26.2 mm, rostrum 9.1 mm, basal width 

 6.9 mm, cheJiped 45 mm, chela 19.8 mm, dactyl 10.5 mm, ambulatory 

 legs 51.5, 40, 35.5, and 32 mm, respectively. Ovigerous female: length 

 29.7 mm, branchial width 21.9 mm, hepatic width 18.7 mm. 



Color in life: Red, varying from bright to dark and often closely 

 matching certain of the encrusting corallines. (Weymouth) 



Habitat: Found abundantly between tides, usually where there is a 

 growth of algae or coralline. The young are found among the roots of 

 eel-grass and often in the burrows of the pistol [shrimp], Crangon. 

 Frequently overgrown with hydroids and coralline. (Weymouth) 



Depth: Usually intertidal, but recovered from a maximum depth of 

 53 fathoms, off Santa Cruz Island, by the Velero III. 



Size and sex: The largest specimens come from the northern part of 

 the range and so are not represented among Hancock collections. Hart 

 (1940) records from British Columbia a male measuring 44 by 36 mm 

 and a female measuring 33 by 26.5 mm. 



Breeding: Egg bearing females were obtained by Weymouth (1910) 

 at Monterey in June, July, and early January. Evidence of both summer 

 and winter breeding was also obtained by Hancock Foundation parties, 

 who found ovigerous females in Marin County in November, in Mon- 

 terey County in February and in August, in San Luis Obispo County in 

 December, in the Northern Channel Islands in April, October, and 

 December, in Los Angeles County in August, December, and January, 

 and in Lower California in June. 



Remarks: Long believed to attain its southern limit of range at San 

 Diego, Pugettia richi has been found at half a dozen stations in northern 

 Lower California as a result of collecting done by C. L. Hubbs, E. Yale 

 Dawson, M. Woodbridge Williams, William K. Emerson, and the 

 Velero IV, and is now known to extend as far south as San Geronimo 

 Island, Mexico.
