not much elevated, its width about 2 in its depth. Orbit large, 3 in head ; 

 snout about 1 in orbit. Interorbital space concave, 2 in orbit, with a 

 median groove bordered by a pair of ridges diverging backward. Cranial 

 ridges well developed, the preocular, postocular, tympanic, and parietal 

 spines present, sharp. Mouth moderate, jaws about equal, maxillary 

 about 2 in head, reaching to vertical from posterior border of pupil; the 

 lower jaw with a small symphyseai knob. The upper preopercular spines 

 nearly e< | ual, sharp and long, the third shorter and broad; lower oper- 

 eular spine horizontal, the upper larger and directed somewhat upward. 

 Gill rakers moderate, the longest about 3 in orbit, 21 on horizontal limb of 

 first arch. Scales moderate, ctenoid, accessory scales numerous, mandible 

 naked; interorbital space, preorbitals, maxillaries, the rays of the dorsal, 

 anal and caudal fins, and the median rays of the pectorals scaly. Fourth 

 dorsal ray longest, about 2^ in head, the twelfth about 2 in the fourth, 

 the dorsal rays shorter than the longest spines ; second anal spine much 

 longer and stronger than third, about 2 in head, the rays equal to the sec- 

 ond spine; caudal slightly emarginate; pectorals moderate, reaching a 

 little beyond vent, the median rays longest, 3 in length of body, base of 

 fin a little less than orbit, the 7 lower rays simple, somewhat thick- 

 ened; ventral rays reaching vent. Color in alcohol, like S. rosaceus; 

 dark brownish above, paler below ; a small pale pinkish spot immediately 

 under base of fourth dorsal spine, and another small one immediately 

 under base of eighth spine; a third larger spot just above lateral line and 

 under the ninth spine ; a fourth spot immediately under the first, and a 

 fifth under the last dorsal rays; peritoneum dark brown, speckled with 

 black dots. Distinguished from Scbastodcs rosaccus by the absence of the 

 supraocular spine. Length 9 inches. Coast of California. One specimen 

 taken on a trawl line at Cortez Banks, near San Diego. (Named for the 

 late Dr. William O. Ayres, of San Francisco, an excellent naturalist, one 

 of the pioneers in the study of the fauna of California.)

Head 2; depth 3. D. XIII, 14; A. Ill, 6; lateral line 58, the accessory 

 scales very numerous. Body oblong, more elongate than in related species ; 

 maxillary 2 in head, reaching beyond pupil; jaws about equal; pre- 

 orbital narrow. Eye very large, 3- in head. Preopercular spines long. 

 Gill rakers as in S. rosaccus ; mandible finely scaled near the base. Dorsal 

 fin moderately emarginate, lower than in rosaceiis, longest spine nearly 3 

 in head; soft dorsal as high as spines; caudal slightly notched; second 

 anal spine longer than in any other species, longer than maxillary, higher 

 than soft rays, length of head; pectoral reaching past ventrals, nearly 

 to anal, 3| in body. Skull long and narrow, the bones thin; preocular, 

 supraocular, postocular, tympanic, and parietal spines present, long, 

 slender, sharp, the ridges thin, high, parietal bones well separated, inter-
