Lycodopsis scaurus sp. n. 



Plate XXXII. fic). 1. 



Br. r. 6 ; D. 95 ; A. 85 ; V. 3 ; P. 21 ; C. 10. 



In this species the form is inoderatelj elongate and tapering, and the 

 body cavity from the snont to the vent is one and three fourths times the 

 length of the head, or nearly one third of the total length. Head com- 

 paratively large, not far from one fifth of the total length ; parietal region 

 broader than long, flat ; iiiterorbital section narrow, longitudinally arched ; 

 snout broad, shorter than the orbit, blunt, rounded ; labial region swollen 

 in the anterior half, to below the eye. Orbit large, more than one fourth 

 of the head. Mouth wide, hardly reaching a vertical from the middle of the 

 orbit; lower jaws shorter, included. Teeth small, in a single row on the 

 intermaxillaries, in a baud on the uiandibles, absent from vomer and pala- 

 tines. Nostrils prolonged in a short tube. Pseudobranchia^ small, with six 

 bars. Gill openings wide, membranes joined to the isthmus opposite the 

 bases of the ventrals. Six branchiostegal rays. Pectorals short, two thirds 

 as long as the head, broad, with twenty-one rays, scalloped on the lower 

 portion of the hinder border. Dorsal low, long, originating above the axil 

 of the pectoral. Anal elongate, low, first ray below the sixteenth ray of the 

 dorsal. Caudal short, rounded, of ten rays, not distinct from dorsal and 

 anal. Ventrals short, club-shaped, broadened toward the outer end, shorter 

 than the eye, with notches at the outer end. Scales small, separated, com- 

 paratively few on the muscles above the abdominal chamber, more numer- 

 ous posteriorly, absent from the head. Lateral line rudimentary or obso- 

 lete. 



Color brownish, on fins and lower surfaces of head blackish. 



Total length seven and one half inches. 



This form is closely allied to L. pacifims Coll. but differs in numbers of 

 fin rays, in proportions, and in color; it is also closely allied to L. paucidens 

 Lock, and probably both should be placed as varieties of Collett's species. 

 Tlie locality given for L. pacificiis is Japan, that for L. pavcidens is San 

 Francisco, California, and northward in moderate depths.
