forming dusky bars, running obliquely forward and down- 

 ward to considerably below the lateral line, tliese often 

 obsolete; the bar at the nape saddle-like; lining of gill 

 cavity dusky; pectoral yellowish, dusky at tip ; an obscure 

 dusky streak along lower parts of sides running into lower 

 lobe of caudal. Head 3^ ; depth 4 to 5. D. X-I, 24 or 25 ; A. 



I, 7; scales 6-55 (pores)-12 Americanus, 100. 



ii. Outer teeth of upper jaw less enlarged ; spinous dorsal elevated, 

 the longest spine reaching past front of soft dorsal, its length 

 li in head ; coloration strongly marked, body scarcely sil- 

 very. Profile slightly depressed above the eyes ; eyes small, . 

 2-} in snout, 2 in interorbital area, about 7 in head ; snout long, 

 bluntish, 3£ in head ; mouth large ; maxillary reaching 

 middle of eye, 2f in head ; ventrals 1| in pectorals, which 

 are \\ in head ; scales all ctenoid. Color dusky gray above, 

 sometimes blackish, the back and sides with distinct dark 

 oblique cross-bands running downwards and forwards, the 

 anterior one at the nape extending downward, meeting the 

 second and thus forming a V-shaped blotch on each side ; a 

 dark lateral streak bounding the pale color of the belly, most 

 distinct posteriorly, and extending on lower lobe of caudal ; 

 inside of gill-cavity scarcely dusky ; pectorals dark. Head 3$ 

 to 4 in length ; depth 4^ to 4|. D. X-I, 26 or 27 ; A. I, 8; scales 



7-53 (pores)-14 Saxatilis, 101. 



lilt. Mouth smaller, the maxillary reaching scarcely to front of eye, 3£ 

 in head ; teeth on lower pharyngeals bluntish ; coloration 

 grayish, with dark streaks along the rows of scales. Snout 

 long, little projecting, 3i in head ; eye small, 7 in head, 2j- in 

 snout, 1£ in interorbital area; outer teeth in upper jaw 

 moderately enlarged, about as in M. saxatilis ; lower pharyn- 

 geals a little broader tban in M. americanus, the teeth 

 coarser, and many of them bluntish, none of them really molar, 

 those of the inner posterior corner of the bone much enlarged ; 

 ventrals 1£ in pectorals, which are 1£ in head ; scales all 

 ctenoid. Color sooty-grayish, with bright reflections ; the 

 back, all the fins, and under side of head dusky; undulating 

 lines along sides running upward and backward, made of 

 dark points in center of each scale ; back often with very 

 faint dark cross-bars ; edge of opercle dusky ; lining of gill- 

 cavity slightly dusky. Head 4 in length ; depth 4 to 5. D. 



X-I, 25 or 26 ; A. 1, 8 ; scales 7-60-11 Undtjlatus, 102. 



cc. Gill-rakers present, very short and somewhat slender ; lower pharyngeals 

 rather broad ; some or nearly all of the teeth molar, i. e., 

 enlarged, with thickened, rounded heads, the molar teeth 

 covering at least the anterior portion of the bone ; teeth in 

 the outer series of upper jaw scarcely larger than the others ; 

 scales on breast small. ( Umbrula Jordan & Eigenmann.) 

 k. Upper lobe of caudal longer than lower ; scales rather small, 

 about 25 in an oblique series from vent forward to lateral 

 line; axillary scale one-third length of pectoral ; snout very 

 little projecting; gill-rakers very short, 3 -f 5, the longest 

 about one-third diameter of pupil ; lower pharyngeal bones 

 narrower than in littoralis, the molar teeth smaller, covering 

 the whole anterior part of the bone ; conical teeth on poste- 

 rior part of the bone, the outermost row enlarged : body
