FROM CALIFORNIA. WITH NOTES ON ITS LIFE HISTORY Based upon some badly mangled remains found in the stomach of a sperm whale, Physeler catodon, which had been harpooned during November 1970 about 115 km west of San Francisco, Rice (Bull. So. California Acad. Sci.. 91:158. 1972) reported the first occurrence of the giant seadevil, Ceratias hol- bolli, from Californian waters. Fourteen months after the first specimen was found a second individual (Fig. 1) was captured in an otter trawl which was being fished on the bottom in 293 to 375 m from lat. 41°23.8'N long. 124°29.9'W to lat. 41°22.2'N long. 124°30.3'W (near Redding Rock off the mouth of Redwood Creek, Humboldt Co., California). Emery Wilson, skipper of the trawler Mineo Bros., informed me that during the tow which yielded the giant sea- devil, the net dropped into the head of a submarine canyon and undoubtedly fished deeper than the 200 fms. (375 m) registered by his fathometer. This seadevil, a female 525 mm SL (700 mm TL) and weighing 4990 g, was netted on 11 January 1972. It had a parasitic male 37 mm SL attached to the midline of the bally at a point approximately one head length in advance of the anal fin. Although the illicium was missing on the female, it did not appear to have been broken off during capture or subsequent handling. The loss of its illicium could have affected its feeding behavior in that it no longer could lure prey species within easy "striking" dis- tance, and thus would be forced to seek out food items not normally utilized. Unfortunately, I was unable to find any accounts of stomach contents for Ceratias holbolli, so I could not compare the items found in the specimen at hand with those reported for "normal" individuals. The stomach of the Redding Rock seadevil contained o
