BROTULA ORDWAYI, new species 



Figure 7 



Head 4.25 ; depth 4.4 ; D. 110 ; A. 85 ; P. 23 ; scales about 225 (too 

 small and irregular to emimerate accurately). 



Body moderately elongate, rather strongly compressed throughout, 

 its thickness at tips of pectoral fins only about half its depth at same 

 place ; head compressed, rather narrow and definitely convex above, 

 its depth at margin of preopercle 6.0 and its width at same place 9.1 

 in standard length; snout a little longer than eye, 4.1 in head; eye 

 elongate, 5.4 ; interorbital narrow, convex, 8.0 in head ; mouth mod- 

 erate, slightly oblique; lower jaw notably shorter than the upper, 

 included ; maxillary broad, reaching vertical from posterior rim of 

 orbit, 2.25 in head ; anterior pair of barbels of snout larger than the 

 lateral pair and of about the same length as the nasal barbels, 2 prom- 

 inent flaps of skin between the anterior and lateral barbels, the 6 

 mandibular barbels all of about equal length; a pair of pores between 

 the anterior barbels, and i between the anterior and the lateral 

 barbels ; lips rather thick, rugose ; teeth small, pointed, in bands on 

 jaws, vomer, and palatines, the band on vomer broadly triangular, 

 approaching a U -shape; 3 gill rakers and 10 rudiments on lower 

 limb, and 4 rudiments on upper limb of first arch ; lateral line running 

 high, broadly arched anteriorly, nearly complete ; scales small, strongly 

 striate, extending forward on the snout, and on the fins, about 30 

 oblique rows between posterior rim of orbit and base of opercular 

 spine ; dorsal fin long and low, its origin about half an eye's diameter 

 in advance of base of pectoral, its distance from tip of snout 4.0 in 

 standard length, the longest rays about as long as snout and half 

 the eye; caudal fin rounded, fully united with the dorsal and anal, 

 only a little longer than snout; anal similar to the dorsal, its origin 

 well in advance of midlength without caudal fin, its distance from 

 tip of mandible 2.4 in standard length; ventrals short, the longest 

 filament 3.1 in head; pectoral fin broadly rounded, scarcely reaching 

 halfway to origin of anal, 2.0 in head, 8.7 in standard length. 



Color very dark brown ; sides and upper surface of head and body, 

 to or a little beyond vertical from origin of anal, with many round 

 black spots, the largest ones nearly as big as pupil ; ventral fins 

 dusky ; other fins very dark brown, nearly black, with a very narrow 

 pale margin. 



The foregoing description is based on the holotype (U.S.N.M. 

 No. 144259) and only specimen known, which is 375 mm. in total and 

 347 mm. in standard length. It differs rather prominently from the
