Science. 264 BULLETIN 18 9, UNITED STATES NATIONAL MUSEUM of ventral spine than vertical from end of dorsal; ventral inserted rather less than half an eye's diameter behind base of pectoral, in head; axiUary process of ventral broadly rounded, about half length of eye; pectoral moderately large, reaching well beyond tip of ventral, 1,15 in head, in length. Color grayish brown above, becoming paler with bluish reflections on side; pale with dusky points underneath; first dorsal, anal, ventral, and pectoral quite dark, the pectoral being darkest on inner side; second dorsal and caudal more or less olivaceous, with dusky punc- tulations at least along margins. This species is represented by a single specimen, 200 mm. (165 mm. to base of caudal) long ( No. 128004), taken in a gill net in Paita Bay by the Mission. This species is rather near M. nasus (Giinther), known from Panama Bay and northward to the Gulf of California, differing in having a slenderer body, smaller scales, appar-.

From the type, 200 mm. long, Paita Bay, Peru ( No. 128004). ently in having one more dorsal spine, one fewer anal ray, and in having only one instead of two dorsal spines produced, These and a few other apparent differences are shown in the accompanying parallel comparison, based on the specimen described, and on 4 specimens, 145 to 255 mm. long, of M. nasus from Panama Bay. M. nasus Body only moderately slender, its depth to in length; caudal peduncle to in head. Head notably deeper than broad over margin of preopercle. Scales 66 to 58; 25 or 26 vertical series on side between origin of anal and base of caudal. Dorsal rays X-I, 21 to 23. Anal rays I, 8. Second and third dorsal spines produced, reaching far beyond origin of second dorsal if defiexed, to in head. Ventral with a pointed axillary process, about as long as eye. M. paitensis Body rather
