anal origin. Vent close before anal, but abdominal serrse not along 

 nicies. Last abdominal serrature (counted as one above) a series of 

 3 small transverse spines before vent. 



Color when fresh in rum with back bright or shining metallic-bluish 

 in some lights, ground-color grayish-brown, and many obscure under- 

 laid and rather crowded small pale dusky spots, these all much less 

 than pupil, mostly only prominent above 1. 1. and scarcely evident 

 below. Midway between dorsal origin and I. 1. spots a little larger 

 and more sparsely distributed than others. At shoulder above, just 

 behind upper portion of exposed shoulder-girdle bones at beginning 

 of 1. 1., a blackish blotch nearly equal to eye in extent, and of rather 

 irregular triangular shape. Side of body below 1. 1. with general pale 

 or whitish shade, but along its upper regions quite soiled with didl 

 brownish, made up of minute dots. Head dull brownish above, sides 

 tinged dull rosy, upper sides with olivaceous reflections, and under 

 surface brilliant vermilion about branchiostegals and lower preopercle 

 limb. From latter point all lower surface of head tinged or blushed 

 rosy. Opercle ruddy, with smutty tints. Lips dusky. Iris deep 

 and warm brownish. Chest, breast, axillary region of pectoral, and 

 all region about abdominal serrse brilliant or blushed vermilion. 

 SerraB on abdomen pale or whitish, like teeth. Dorsals and caudal 

 dusky largely. Rayed dorsal somewhat tinged with olivaceous, and 

 adipose fin rather brownish. Caudal margin behind blackish, also 

 base, and intervening region brownish. Inside mouth and gill-

Head 3 to 3f; depth If to If; D. usually ii, 14, i, often ii, 15, i, 

 rarely ii, 13, i; A. usually iii, 30, i, often iii, 29, i, rarely iii, 28, i; 

 scales in 1. 1. according to tubes 58 to 69 + 5 to 7; scales counted in 

 lateral series above 1. 1. 78 to 80 + 7 or 8; predorsal scales 47 to 53: 

 scales above 1. 1. to dorsal origin 30 to 35; scales below 1. 1. to ventral 

 origin 25 to 30; scales below 1. 1. to anal origin 30 to 35; abdominal 

 serrse usually 21, sometimes 22, rarely 14 + 9; snout 3| to 4^ in head 

 measured from upper jaw tip; eye 2| to 3^; maxillary 2|- to 3 ; inter- 

 orbital 2^ to 2|; length 2f to 4^ inches. These examples all agree 

 largely with the type, except that the two smallest show posteriori}' 

 on each palatine a small tooth. In color they also differ somewhat in
