The San Fran- cisco, California, record for M. xenarcha has not been plotted. southern California to Mazatlan, and 31. rosacea and M. prionura are limited to the Gulf of California and the adjacent Mexican Coast as far south as Bahia Banderas. It is not eas}^ to account for these limited distributions, particularly since all of the species of Mycteroperca pre- sumably have pelagic eggs and larvae (Smith, 1961). In support of this view, it is known that the spawning season for M. rosacea in the south- ern part of the Gulf of California ends by April (E. S. Hobson, pers. commun.), and the young do not appear inshore until late June or early July. We have no such information for the other species, but it might be noted that our smallest specimen of M. jordani (30 mm) has elongate preopercular and second dorsal spines, characters suggestive of the pelagic prejuvenile of other serranids. It seems highly probable that fcAV species of Mycteroperca occur along the coast of Central America, and that the paucity is related to ecological factors. M. xenarclia is commonly taken in mangroves, and the other species seem to be more often associated with rocks. Certainly the rocky-shore habitat is less well developed south of Mexico, but it must be pointed out that other rock-dwelling serranids, such as Epi-.
