Eye-s large, close together, the interorbital space half pupil. Orbit 

 34 m bead, longer thau suout. Posteriol? nostril with a short flap, the 

 tube obsolete. Mouth large, somewhat oblique, maxillary reaching 

 middle of orbit, 2* iu head. Top of head with very large pores, a series 

 running backward from each eye, the two joined by a cross-series on 

 occiput. 



Body covered with very small cycloid scales, including belly, nape, 

 breast, and cheeks, those on breast and cheeks not imbricated Lateral 

 line without visible pores. 



Spinous dorsal beginning well forward, the distance from its origin to 

 nape less thau from latter to posterior margin of orbit. Anterior spines 

 short, but fully united by membrane, the longest spine 3^ in head. 

 Membrane of last spine reaching base of upper caudal rays. Origin of 

 anal very slightly in advance of middle of body. Anal with two short, 

 sharp spines, the rays longer, their terminal third free from membrane. 

 Last anal ray connected with base of lower caudal ray. 



Ventrals well developed, nearly half head. Pectorals with lower- 

 most rays abruptly lengthened, two-thirds head. Caudal short, rounded, 

 little more than half head. 



D. LVI ; A. II, 34. 



Color: Dusky olive above, lighter below; sides crossed by about 

 25 narrow white bars, narrower than interspaces. Three equi-distaut 

 dark blotches near back, each double, the two halves occupying con- 

 tiguous interspaces between white bars. Branchiostegal membrane 

 black. Head without markings. Pectorals white at base, the distal 

 half black, margined with white. Ventrals white. Dorsal with alter- 

 nating oblique bars of white and blackish, two jet-black roundish spots 

 on its posterior portion. Caudal whitish at base, then dusky, margined 

 with white, its upper ray jet black. Anal light at base, becoming black 

 at edge of membrane, the free tips of rays white. 



A single specimen, 4 inches long, from Station 30G4, iu 46 fVithoms. 



Lucioblennius gen. uov. {Blenniida'). 



Body very elongate, wholly naked; gill membranes broadly united, 

 free from isthmus; dorsal fin single, extending along the entire back, 

 its anterior half spinous. Ventrals in front of pectorals, I, 2. First 

 two anal rays spinous. Last rays of dorsal and anal joined to caudal. 

 Teeth conic, not movable, in jaws and on vomer and palatines. 



Type, Lucioblennius alepidotus sp. nov. 



66. Lucioblennius alepidotus sp. nov. 



Body much compressed, slender throughout, the head rather deeper 

 and wider than body. Snout long, depressed, and rather wide; the 

 anterior profile descending very gradually. 3Iouth nearly horizontal, 

 the lower jaw protruding, the gape extending to much behind orbit, the 

 entire physiognomy remarkably pike-like.
