Described" from three specimens ^ collected at Borja Bay, two from 

 Sandy Point, and two from Otter Bay; the largest, from the latter 

 place, 215 mm. in total length, is used as typical. 



Head 3i (0.29 to 0.32) of body length; depth 3§ (0.23 to 0.29); 

 eye 4f in head (0.06 to 0.08) ; snout 3;^ (0.08 to 0.09) ; length of max- 

 illary 2| (0.09 to 0.115) of mandible 2 J (0.11 to 0.12) ; width of inter- 

 orbital space 2| (0.09 to 0.13); length of pectoral If (0.20 to 0.25); 

 of ventral If (0.17 to 0.20); of combined dorsal bases If in body; 

 of anal base 2J; D. V (or IV), 30 (29-31); A. 24 (or 23); pectoral 

 rays 17; scales with pores in upper lateral line 43 (38 to 46), in lower 

 10 (8 to 14) ; in lateral series 61 (58 to 64) ; in transverse series 8 + 22; 

 gill rakers 6+ 11 (17 to 19). 



Head massive, broad above, with romided snout and vertical 

 cheeks; profile arched most strongly before eyes on snout; inter- 

 orbital nearly fiat, arched slightly from side to side; maxillary ending 

 imder anterior edge of pupil (under anterior quarter of eye in yoimg) ; 

 jaws equal; width of velar flap measured from tip of lower jaw two- 

 thirds diameter of eye; eye looking laterally, upper sm^ace of eyeball 

 not exposed; interopercle nearly as wide as preorbital; teeth of jaws 

 in two loose rows anteriorly, one laterally, small, a pair behind second 

 row at symphysis of lower jaw; gill rakers very short and thick. 



Space between last spine and fh"st dorsal ray equal to two or three 

 interspinous spaces; spines stiller than usual, longest of them thi'ee 

 or four in head length ; anterior portion of soft dorsal elevated, length 

 of its rays contauhng that of posterior part one and two-thirds times ; 

 dorsal and anal tenninating opposite each other and a trifle more than 

 depth of caudal peduncle from last of muscular part of latter; anal 

 similar to second dorsal but shghtly lower; pectoral falcate, more so 

 in adults than in young; ventrals reaching three-fifths to two-thirds 

 distance to anus; caudal emarginate. 



1 As the original description of this nominal (7) species is somewhat difficult of access the following 

 abstract is given in translation. The locality is so far north of other records as to require confirmation if 

 It is N. macToccphala: 



Depth at insertion of anal contained 5^ times in total length; width at pectorals 4J; length of head 4f in 

 same; width of interorbital space 2| in head; top of head with many rough granulations and minute scales. 

 Nasal tube large. Eye 2i in length of snout. Scales large on opercle, preopcrcle, and posterior edge of 

 eye (translation?). Upper lateral line terminating opposite last ray of second dorsal; lower beginning on 

 a line between the sixth from the last rays of the dorsal and anal. Color variable, greenish brown, darker 

 above. Irregular blotches forming one or two irregular bands laterally, interrupted by yellowish green 

 color. Pectoral with circular yellow spots, faint distally, a large irregular blotch on the axilla. Dorsal 

 and anal green, obscured by a pattern of greenish yellow of diflerent hues. Caudal similar with a clear 

 vertical band. Rays of dorsal and pectoral only vary in number "D, IV-VI, 28-30; A. 24; P. 18-19."
