the eyes the effect of protruding ; a single canine on either side below,

 jaw; the two corner teeth on each side of the lower jaw somewhat 

 detached from rest of series and caninelike ; depth 4.3, head 4.2, both 

 in standard length ; third spine of dorsal highest, with fin shortening 

 rapidly posteriorly, next-to-last spine onlj' half length of third spine 

 or first ray, last spine a tiny nubbin almost buried in basal membrane 

 of fin ; third ray of soft dorsal longest ; this part of fin also shortening 

 rapidly posteriorly; membrane binding last ray to caudal peduncle 

 covering first three or four small rays of caudal ; soft dorsal a little 

 higher than spinous dorsal, with deep notch between two parts of 

 fin ; anal lower than spinous dorsal ; both anal spines plainly visible, 

 the second being two-thirds the length of first ray, the first two-thirds 

 the length of second; all rays except last with a small fleshy pad at 

 the tip; last fully bound to caudal peduncle by membrane; genital 

 papilla or tube of male a little longer than wide ; caudal with 13 prin- 

 cipal rays and 7 small rays both above and below ; middle caudal rays 

 equal head in length; third and fourth dorsal principal rays greatly 

 elongated, extending beyond level of fin by two-thirds the length of 

 middle rays ; third principal ray from ventral edge of fin only slightly 

 extended ; none of caudal rays forked ; longest pectoral and pelvic rays 

 approximately equal in length and shorter than postorbital length 

 of head by one-third the diameter of eye; third ray of pelvic, while 

 entirely bound to, and much more slender than, second, plainly visible ; 

 pelvic spine not visible without dissection. 



Coloration. — Male : Peritoneum black ; throat noticeably paler than 

 sides of head and without markings; rest of head and the body a very 

 dark reddish brown ; a darker band as wide as pupil extending back 

 from eye to edge of opercle ; two horizontal light bands, each as wide 

 as pupil, run full length of body, one from upper corner of opercle 

 to upper part of caudal base, the other from under the pectoral to 

 loM' er pail of caudal base ; no spots or other markings on head or body : 

 spinous dorsal clear and transparent; soft dorsal with a clear band 

 at base, then a narrow dusky band which shades off above to leave 

 most of fin clear and transparent ; middle third of caudal dusky, upper 

 and lower thirds mostly clear; anal uniformly dusky with pads at 

 tips of rays a little paler; pectorals clear; pelvics uniformly dusky.

 forward of the orbits and the resultant backward slope from the 

 forehead to the upper lip.
