Description: See species description under Portunus xantusii xantusii.
Material examined: 1,402 specimens from 148 stations (See Table
6). Extralimital from E of South Coronado Island. From Magdalena
Bay, Lower California, and from Rocky Point, Gulf of California, to
Tenacatita Bay, Jalisco, Mexico, and from shore to 55 (exceptionally to
150) fathoms.
Measurements: Males from 7.0 x 12.5(9.6) to 24.9 x 43.2(36.5)
mm, females from 7.2 x 11.5(9.9) to 24.1 x 40.0(34.1) mm, ovigerous

center band encircling them; tips yellowish white. First three ambulatory
legs white or pale gray with two distinct bands of carmine encircling
each segment. Eyes dark brownish red. Ventral side white except for
