A large population of Neocrangon resima (Rathbun, 1902) is reported for the northern Gulf of California, Mexico, in depths of 205-580 m, with environmental conditions varying from 6.21 to 11.29ºC and 0.50 to 1.54 ml O2/l. With a total of 33 specimens collected, this is the largest sample reported to date for the northern Gulf of California. The species had previously been reported from two localities. The distribution range in this area is increased by ca 1º30' of latitude to the south. Maximum and minimum estimated densities were of 2.7 and 54.0 orgs/ha, thus indicating that a relatively large population of N. resima occurs in the area.
