 esses protruding before it; lower jaw longest; maxillary reaching ver- 

 tical behind pupil, 2f in head. 



Teeth in the jaws in narrow, villiform bands, becoming a single series 

 on sides of lower jaw; those of the outer and inner series in each jaw 

 are somewhat enlarged, the largest being the single series in sides of 

 lower jaw. Preopercular spine as usual in the genus. 



Scales smooth above and below, ctenoid on sides. 



Head 31 in length; depth 4^. D. VI-9; A. 9. Lat. 1. 48. Eye 6f in 

 head; pectoral li; ventral 1|; highest dorsal ray 2; highest anal ray 2; 

 caudal IJ. 



97. Gobius encaeomus sp. uov. (29673.) 



Three specimens, two males and one female, were obtained in tide- 

 pools in the harbor, the largest I'l inches in length. The type is num- 

 bered 29,673 on the register of the United States National Museum. 



Colors in life : S light olivaceous, mottled above with darker olive 

 brown ; a series of about 4 obscure oblong dark blotches along middle 

 of sides; a dark spot at base of caudal ; each side of nape with an intense 

 blue-black spot larger than eye; an obscure dusky streak from eye for- 

 ward to mouth ; a small dusky spot sometimes i)resent on upper portion 

 of base of pectorals. Both dorsals translucent, with series of bright red- 

 dish-brown spots, as large as pupil ; upper lobe of caudal light reddish, 

 the lower lobe blue-black. Anal and ventrals dusky-bluish ; pectorals 

 slightly dusky, with a narrow, bright pink border behind. 



$ without bright markings ; body light olive, with 5 oblong dark 

 blotches on sides, the last on base of caudal ; from each of the three 

 middle blotches a V-shaped bar runs to the back (these visible also in 

 males); back somewhat mottled with dusky; a black blotch on scapula; 

 a small one on opercle ; a dark bar from eye forward to mouth. Vertical 

 tins with dusky streaks, these appeariug on caudal in the form of cross- 

 bars. Ventrals light, with two lengthwise dark streaks ; pectorals 

 plaib. 



Head 4 in length ; depth 5f . D. VI-11 ; A. 12. Lat. 1. about 37 (a 

 few of the anterior scales gone, the count, therefore, not certain). 



Body very elongate, much tapering backwards ; head compressed, the 

 cheeks high and vertical ; snout very short, compressed, obtusely 

 rounded vertically. Mouth nearly hoiizontal, low, large, the maxillary 

 one-half head, nearly reaching vertical from posterior margin of orbit. 

 Teeth in very narrow bands in both jaws, those of the outer series in 

 the upper jaw much enlarged; eyes inserted high, the interorbital space 

 very naxrow, about as wide as pupil ; diameter of orbit much greater 

 than snout, nearly one-third head. Gill-opening 2J in head ; the isthmus 

 wide. Dorsals contiguous, the membrane of spinous dorsal reaching 

 nearly to base of soft dorsal ; dorsal spines high, of nearly uniform length, 

 the last reaching well beyond origin of soft dorsal when depressed ; 

 the longest spine about half length of head. Soft dorsal and anal long
