208 BULLETIN OF THE 



from the tip of the snout is contained 4§ times in the total length ; that of the 

 anal from the snout, 2^ times. The vent is immediately in front of the anal. 

 The length of the pectoral equals one half that of the head, or a little more. 

 The distance of the ventral from the snout is contained 8-^ times in the total 

 length. The length of the ventral is scarcely more than that of the pupil. 

 The interorbital space (on the skull) is about one fourth the length of the 

 snout, which is about equal to that of the eye, which is contained 3^ times in 

 the length of the head. The tubular nostril is much nearer the tip of the 

 snout than to the eye. The scales are very small, present everywhere except 

 on the head and the pectorals, extending almost out to the margin of the ver- 

 tical fins. Dorsal (with half of caudal) 118 rays ; anal (with half of caudal) 

 110. Pectoral 16, ventral 3. Color light brown, the head somewhat darker. 

 Specimens were obtained at the following places. 



LYCODOISrUS, new genus. 



This genus is in nearly every particular like Lijcodes, from which, however* 

 it is distinguished by the peculiar structure of the dorsal and anal tins. 



Diagnosis. — Body blenniform, elongate. Scales small, circular, imbedded 

 in the skin. Lateral line very short, posteriorly obsolete. Eye moderate. 

 Jaws without fringes. Upper jaw longer than lower. Fin rays soft, articu- 

 lated ; those of the dorsal and anal fins supported laterally, each by a pair of 

 sculjJtured ectodermal scutes or plates. Caudal distinct ; not fully connate with 

 dorsal and anal, few-rayed. Ventrals present, jugular each composed of a 

 few slender deeply cleft articulated rays. Gill opening rather narrow. 

 Branchiostegal membranes broadly joined to the isthmus. Teeth as in 

 Lycodes. Pseudobranchia; apparently present. Branchiostegals apparently 

 five. Gill arches four. Gill rakers rudimentary, in moderate number. Air 

 bladder and pyloric cseca apparently absent. 



Lycodonus mirabilis. new species. 



The body is shaped much as in Lycodes Verrillii ; its greatest height, at ori- 

 gin of dorsal, contained about eighteen times in the length of the body. Scales 

 as in Lycodes, the scales not extending out upon the fins. The head and nape 

 are also scaleless. Lateral line apparently obsolete posteriorly, not extending 

 back of the extremity of the pectoral. 



The length of the head is contained about seven times in the entire length. 

 The diameter of the eye is contained 2| times in the length of the head, and is 

 about equal to the postorbital portion of the head. The eye is pkced high, the 

 width of the interorbital space being less than the diameter of the pupil, and
