609. PHANERODON, fJiraid. 

 Phanerodon, Girard, Proc. Ac. Nat. Sci. Phila. 1854, 153 (furcatus). 



This genus is very close to Emhiotoca, Ditrema, and Ta'niotoca. From 

 Enibiotoca, Phanerodon differs chiefly in the long and slender caudal pedun- 

 cle, and in the larger number of Tertebrte, 14 or 15 + 23 or 24^37 to 39; 

 the base of the anal is below 11 or more vertebrre, and the first ha?mal 

 spine is as large as the second ; dorsal spines slender and high, the last 

 ones as high as the soft rays. Species plainly colored, of moderate size; 

 the caudal deeply forked. (0n:7^e/3(3?, evident; 65 oi)?, tooth ; but the teeth 

 are no larger than in related genera.) 



a. Ventral tins plain whitish; scales of hody without orange shades; caudal edged 

 with dusky; head short, 32 in length. furcatus, 1892. 



aa. Ventral fins hroadly tipped with blackish; scales of hody above each with an 

 orange shade at base ; caudal not dusky-edged ; head longer, 3J in length. 



ATRIPES, 1893. 



1892. PHANERODON FURCATUS, Girard. 



(White Surf-fish.) 



Head 3f ; depth 21. D. X, 24 to XI, 22 ; A. Ill, 30 to 32 ; lateral line 6(5 to 69. 

 Body oblong-elliptical, compressed, tapering backward into the long and 

 slender caudal peduncle ; dorsal and ventral outlines about equally curved ; 

 occipital region little depressed ; mouth small; lower jaw included; teeth 

 rather large, conical; gill rakers very short and slender; last dorsal spine 

 highest, sometimes higher than the soft rays, the fin higher than in rha)ie- 

 rodon airipes; pectorals reaching a little beyond tips of ventrals; caudal 

 fin strongly forked, the upper lobe usually the longer. Light olivaceous, 

 silvery below, sometimes yellowish ; scales with bright reflections but no 

 red markings; usually a round dusky spot on the anal; ventrals plain; 

 caudal fin edged behind with dusky; fins usually yellowish tinged. Length 

 1 foot. Pacific coast, from Vancouver Island to San Diego; extremely 

 abundant from Cape Mendocino southward, (fiircatm, forked.)

* The name Holconotus was invented by Gibbons independently, and is not synonymous 

 with Holconotus of Agassiz.
