28. ECHENEIDIDtE. 



66. Echeneis naucrateoides Zniew. — Sucker, 



A young individual, No. 21,482 (13), 6 mches in length, remarkable 

 from the fact that the tip of the caudal fin is cuneate in outline. The 

 coloration is much the same as in adult individuals of the si)ccies, except 

 that the white on the dorsal, anal, and caudal fins is more conspicuous 

 and occupies a wider area. The dorsal and anal fins are essentially 

 white, with the spaces at the base of tlie fins and between each pair of 

 rays of the same color with the darkest portiou of the body. The white 

 areas upon the high anterior portions of the dorsal and anal occupy 

 more than half of the height of these fins. Upon the i30sterior portion 

 of these fins, the white area is reduced to a marginal line. The white 

 l)atches on the outer angles of the caudal fin are so arranged that the 

 dark portion of this fin is outlined upon the white in a lanceolate form. 

 The pectoral fins are liglitly margined with wliite posteriorly. D. XXI,
