 head; eye 4 J; pectoral 1; ventral 1^; longest dorsal spine 3^; longest soft

 caudal rays 4. Body elongate, elliptical, slender, and symmetrical, moder- 

 ately compressed; snout acute; profile slightly depressed above. Eye 

 moderate, larger than in related species ; maxillary reaching to below front 

 of eye. Teeth conical, rather few and small, in narrow bands or almost a 

 single series. Preorbital very narrow, about one-half eye; suborbital hid- 

 den by scales. Preopercle narrow, largely free, its edge slightly crenulate; 

 gillrakers 36, long and slender; head covered with small scales except 

 throat and tip of snout; those on body large and ctenoid, lateral line 

 strongly curved, continuous, extending downward along the tail, wanting

 light yellow, dusky at base; other fins black, each with a narrow whitish 

 edge. West coast of Mexico. Three specimens from Guadalupe Island, 

 each 6+ inches long. A beautiful fish with a symmetrical outline, unusual 

 in this family. Type No. 5706, L. S. Jr. Univ. Museum. 



62. Chromis punctipinnis (Cooper). Many young from Todos Santos Island ; adult 



examples from Guadalupe, Cerros, and San Benedicto Islands. 



63. Abudefduf saxatilis (Linnteus). Abundant in the tide pools at Clarion Island; 



11 specimens taken. 



64. Eupomacentrus leucorus (Gilbert). Socorro Island, 6 specimens; San Bene- 



dicto Island, 6 specimens; Clarion Island, 4 specimens; a strongly marked 

 species. 



65. Eupomacentrus rectifraenum (Gill). Six specimens from Clarion and Socorro 



islands. 



66. Eupomacentrus flavilatus (Gill). Head 3i; depth 2; D. xii, 15; A. ii, 13; 



scales 29; eye in head3i; pectoral in head 1^; ventral in head 1; longest 

 dorsal spine 2; second anal spine 2; body deep, robust; anterior profile 

 more or less convex and broad; general appearance of J5. rectrifrwnum, from 

 which this seems to differ only in color. No blue spots, even in specimens 

 3 to 5 inches long; posterior part of body, especially pectoral and caudal, 

 light yellow ; rest of body paler than in E. rectrifranum, but color variable ; 

 ventrals black ; dorsal and anal dusky, more or less pale posteriorly ; pec- 

 toral with a very distinct black spot at base of upper rays. The latter 

 species has the tail and caudal as dark as other fins, which is not the case in 

 E. flavilatus. Twelve specimens from Socorro Island, two from Clarion 

 Island, and one from San Benedicto Island. 



67. Hypsypops rubicundus (Girard). One young example, 4 inches long, from 



Guadalupe Island agrees in the distribution of blue spots with Mrs. Eigen-

3-29-10. Body short, compressed, elongated; nape abruptly produced 

 behind and above a depression which lies above eye, nape thus projecting 

 forward in a iieshy crest. Anterior profile steep with fleshy corrugations 

 separated by depressions. Tip of snout above premaxillary enlarged to a 

 fleshy pad, under which the jaw slips, separated from preorbital and top of 

 head by adecp crease, de(>per in larger specimens. Nostril midway between 

 eye and crest, its size much larger than in M. dorsalis, being i diameter of 

 eye. In M. dorsalis of same size the nostril is reduced to a small pore, about
