 Upper half of head and body brown, finely speckled; 4 oblong, colorless 

 areas along base of dorsals and a smaller one on back of caudal peduncle; 

 lower parts abruptly pale ; back with 5 or 6 blackish cross bars reaching to 

 middle of sides, below which they extend as 5 or 6 short V-shaped pro-

Body moderately elongate, compressed, covered with loose, smooth, 

 naked skin. Head large, depressed, with tumid cheeks. Mouth large, 

 the maxillary reaching to beyond the orbit; jaws equal, each with a nar- 

 row band of villiform teeth, the outer teeth slightly enlarged; lower jaw 

 capable of little motion ; snout rounded ; no cirri. Ej-es very small, reduced 

 to mere vestages, covered by skin, and functional only in the young. Skull 

 greatly modified, the brain case quadrate. Fins low ; first dorsal of 2 flexi- 

 ble spines; second dorsal moderate; anal very short; caudal rounded; 

 ventral disk as in Gobius. Gill openings rather narrow. One species 

 known; singular blind gobies, living like slugs under rocks between tide 

 marks. (ru^Adj, blind; Gobius.) 



*Thi8 species, which we suppose to he the adult of Barbulifer ceiithoecus, is thus de- 

 scribed by Dr. Eigenmann: Head 3J (4j in total) ; depth 4i (Sj). T). VII-9; A. 9. Body 

 short and robust, deepest below tirst dorsal spine; head liluut, profile straight from first 

 dorsal spine to eye. much curved in front of eye; ej'o lonuer than snout, :iA in head ; inter- 

 orbital area j diameter of eye; snout blunt; inoutli small, oblique; maxillary 3 in head, 

 reaching to below anterior margin of pupil ; lips thick. About 21 barbels, in length A 

 orbital diameter or longer, arranged as follows: A series of 7 cross the snout from one 

 angle of the mouth to the opposite angle, the anterior 3 on the snout rather thick and 

 colored (2 of them nasal), all the others yellowish, the barbel nearest each angle of the 

 mouth longer tlian any of the others; on the lower jaw a barbel near each rictus, 2 on the 

 chin, behind which are 2 pairs of barbels; posterior to these and below the rictus are 2 

 barbels on each side ; 1 slender barbel on each side of preopercle below the posterior mar- 

 gin of the eye. Numerous rows of pores or ]>apilli« on the head; 1 series extending 

 straight downward on the anterior part of the opercle, from the upper end of which 

 another series extends perpendicularly backward; other pores irregularly scattered on 

 the opercle; a double series extending along edge of preopercle, the pores becoming 

 larger and especially conspicuous below, meeting on the chin ; 6 or 7 series radiating from 

 eye, extending to snout, maxillary, and opercular series below; a row of pores nearly sur- 

 rounding mouth, curving backward, encircling the nasal opening; 1 series about the eye 

 posteriorly, otherwise none on to]) of head or nape; fins high and rounded ; second dorsal 

 higher than first, 14 in head, caudal very broad and rounded, equal to the head iu length; 

 anal lower than soft dorsal; ventral reaching | to vent, IJ in head; pectoral IJ in head. 

 Color yellow; upper lialf of body with a broad band of purjilish spots; 6 diamond-shaped 

 spots of darker cross the band, extending above and below it; nape, top of head, and 

 upper part of cheek covered with dark points; opercle light yellow, cheeks darker; an 

 oblique bar of black points on upper half of i)ectoral base, a curved bar of fainter spots 

 on base of caudal; fins otherwise colorless and transparent. Length 1| inches. (Eigen- 

 manu.)
