margin; entire carpus, including teeth, covered with short setae arising 

 in tufts from distal side of each granule. Manus covered with small 

 projecting granules, arranged in three even longitudinal rows below 

 pollex ; a fourth along outer margin, extending to tip of pollex ; a group 

 of somewhat larger granules near inner margin ; arising from the dis- 

 tal end of each granule a tuft of short setae, these setae, and those 

 of carpus, showing a slight plumosity in larger specimens ; a few 

 scattered longer setae near outer margin. Fingers with somewhat flat- 

 tened small granules, outer margins serrate, devoid of setae; gaping 

 slightly in major cheliped, meeting entire length in minor cheliped, 

 gape devoid of hairs.

Material examined: See Table 47. 



Measurements: Males, 2.9 to 5.2 mm; non-ovigerous females, 4.2 

 to 4.5 mm; ovigerous females, 3.1 to 4.5 mm. The ovigerous female 

 holotype measures 4.8 mm long, 5.2 mm wide. 



Color: Color in alcohol red mottled with white; bristles a straw 

 color. (Glassell, 1936) 



Ecology: Velero III collectors obtained this species at two shore 

 stations, under stones in one case and from coral in the other. It is 

 otherwise known from depths of 2 to 45 fathoms, where it has been 

 dredged on various substrates such as sand, shell, sand and gravel, 

 sand and corallines, and coral and nulHpores. It was taken by the Zaca 

 at 40 fathoms from a bottom of mud and shell. "This species frequents 

 a rather rough bottom, where it is able to secure shelter." (Glassell, 

 1937) 



Ovigerous females have been collected in January, February, and 

 March. 



Range: Bahia de Santa Maria, Baja California; Gulf of Cali- 

 fornia, from Isla Angel de la Guarda south to Arena Bank. Shore to 45 

 fathoms.
