THE SHORE FISHES OF PERU 459 



palatines; normal scales covering entire body; dorsal fins relatively- 

 far apart; anal similar to second dorsal, though somewhat longer; 

 ventral with 1 spine and 5 soft rays; pectoral not especially large 

 or broad, with about 17 rays; vertebrae about 36. 



This genus, which according to Norman (1938, p. 32) probably 

 is the only one of the family found south of the Equator, seems to 

 differ from all the other genera in the uniform and complete scaUng 

 of the body. The discoverer of this genus and its only species (Clark, 

 1937, p. 90) regarded it so unique that he beheved it to represent 

 a new family. However, Norman, in the paper just cited, showed 

 that it may be included in the family Cottidae. 



NORMANICHTHYS CROCKERI Clark 



Normanichthys crockeri Clark, 1937, p. 90, with fig., Valparaiso Harbor, Chile 

 (original description, with names for a new genus and family). — Norman, 

 1938, p. 29, 3 figs., off Mocha Island, Chile, and Valparaiso Harbor, Chile 

 (discussion of affinities, chiefly as to osteology, leading to the conclusion 

 that this species does not represent a distinct family as supposed by Clark 

 but that it belongs to the Cottidae). 



Head 3.1; depth 5.6; D. XI-10; A. 15; P. 17; scales 46. 



Body quite elongate, Uttle compressed, its greatest thickness only 

 a httle less than its depth; dorsal profile anteriorly notably less convex 

 than ventral profile; head pointed, rather flat above; caudal peduncle 

 slender, 5.3 in head; snout 3.8; eye 4.25; interorbital with 2 low 

 bony ridges, concave between ridges, 5.7 in head; mouth obhque; 

 lower jaw strongly projecting, pointed as seen from above, entering 

 dorsal profile; maxillary reaching Uttle beyond front of eye, 3.33 in 

 head; teeth small, pointed, in a narrow band anteriorly in each jaw, 

 reduced to a single series posteriorly; gill rakers rather stout, those 

 at angle almost half diameter of eye, 14 more or less developed on 

 lower, and 6 on upper Hmb of first arch; lateral line complete, with 

 about 43 pores; scales (mostly lost in specimen at hand), strongly 

 ctenoid, extending forward to nape, and present on chest, a few on 

 opercle and on preopercle (opercle, exclusive of margin, glossy without 

 outHnes of scales, contrary to paratype in which round scales are 

 visible), 13 scales on median line in advance of first dorsal, 7 between 

 dorsal fins, 5 rows between it and first ray of second dorsal; first 

 dorsal consisting of flexible spines only, the longest 2.0 in head, its 

 origin a Httle behind base of pectoral; second dorsal consisting of 

 slender soft rays only, a httle shorter than the spines; distance be- 

 tween dorsal -fins equal to snout and half eye; caudal damaged (with 

 shallow fork in paratype), with 7 other rather numerous rudimentary 

 rays extending on peduncle above and below; anal rather long and 

 low, its origin about at vertical from midway point between dorsal 

 fins, its base 1.4 in head; ventral inserted a Httle behind base of pec- 

 toral, reaching about two-tliirds distance to vent; pectoral longer, 

 reaching nearly to vent, 1.4 in head, 4.3 in length.
