224 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 9 



Head subterete, moderate, 3.95 in standard length (25.3%). Head 

 width almost equal to its depth, width 5.93 in standard length (16.8%), 

 depth 6.02 (16.6%). Head bluntly pointed, dorsal and ventral outlines 

 almost equally curved. Snout short, bluntly rounded from dorsal aspect, 

 6.47 in head (5.43% in standard length). Mouth terminal, jaws equal, 

 moderately oblique. Tip of upper jaw at same level as a horizontal line 

 through the center of the eye. Maxillary long, extending backward to a 

 vertical from posterior margin of eye, 1.69 in head (15.4% of standard 

 length). Longitudinal and transverse rows of cutaneous papillae present 

 on head. 



Maxillary teeth in two series. The outer series a single row of 

 enlarged, widely spaced teeth around the edge of the jaw. Inner series a 

 narrow, irregular band of small teeth ; wide anteriorly, tapering laterally 

 to a single, irregular row. Mandibular teeth similar to maxillary teeth. 

 The outer series slightly smaller than those of the outer row of the 

 maxillary. Tongue moderately emarginate. Nostrils paired, anterior 

 nostrils with a short tube, posterior nostrils a round pore. Eyes moder- 

 ate, dorsolateral in position, 3.5 in head (8.45% of standard length). 

 Interorbital very narrow, deeply grooved, 8.5 in eye. Gill-membranes 

 broadly united to isthmus. Attachment of gill-membranes at lower angle 

 of pectoral base. 



Color in alcohol uniform medium brown. An irregular, dark blotch 

 at base of caudal fin. Abdomen pale. Head slightly darker than body. 

 Membrane of dorsal, caudal, and pelvic fins slightly darker than body. 

 Pectoral fin dark at base, lighter distally. Anal fin light. 



Parrella ginsburgi differs from the other known species in having 

 scales across the ventral mid-line of the abdomen. From F. fusca and 

 P. spiloteryx it differs in having a longer maxillaiy, a much narrower 

 interorbital, a more elevated dorsal, deeper body, longer caudal fin, and 

 slightly larger scales. From P. maxillaris it differs in the shorter maxil- 

 lary, scaled predorsal region, and a different color pattern. From 

 P. macropteryx this new species differs in having slightly smaller scales, 

 shorter pectoral and caudal fins, less elevated dorsal, shorter maxillary, 

 and a different color pattern. 



This species is named for Mr. Isaac Ginsburg, U.S. Fish and Wildlife 

 Service, in recognition of his work with this difficult family.
