609. PHANERODON, Girard. 



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



This genus is very close to Enibiotoca, Ditrema, and Tceniotoca. From 

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

 cle, and in the larger number of vertebrae, 14 or 15-}- 23 or 24 = 37 to 39; 

 the base of the anal is below 11 or more vertebrae, and the first hajmal 

 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. ($avepo$, evident; 6dov$, tooth; but the teeth 

 are no larger than in related genera. ) 



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

 with dusky; head short, 3| in length. FURCATUS, 1892. 



aa. Ventral fins broadly tipped with blackish; scales of body above each with an 

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

1892. PHANERODON FURCATUS, Girard. 

 (WHITE SURF-FISH.) 



Head 3f ; depth 2|, D. X, 24 to XI, 22 ; A. Ill, 30 to 32 ; lateral line 66 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 Phane- 

 rodon atripes; 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, (ftircatus, forked.)

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

 with Holconotus of Agassiz.
