 Eyes large. Pectoral H in head. Head 4 in length ; depth 2f . D. 95 or 96. A. 

 76 to 78. Scales 73 to 78. Vertebne 33. Gill-rakers tubercle-like, broader than 

 high. Color brownish, spriukled with dark dots, aud with some whitish rings; 

 large vaguely-defined oval spots on head and body ; dorsal with five or six, anal 

 with three dark spots Paxamensis, 50. 



50. AZEVIA PANAMENSIS. 



Citharichthys panamensis Steindachner, Ichth. Beitr., iii, 62, 1875. (Panama.) Jor- 

 dan & Gilbert, Bull. U. S. Fish Com., 1882, 108 and 111. (Panama.) Gilbert, 

 Bull. U. S. Fish Com., 1832, p. 112. (Punta Arenas.) 



Habitat. — Pacific coast of Central America. 



Our description of this species is taken from the specimens from Pan- 

 ama in the museum at Cambridge, a part of the series of Dr. Steindach- 

 uer's original types. The species is apparently not uncommon on the 

 west coast of Central America. 



Genus XXI.—CITHAKICHTHYS. 



Citharichthys Bleeker, Cornptes Rendus Acad. Sci. Amsterd., xiii, Pleuron, 6, 1802. 



( Cayennensis = Spilopterus. ) 

 Orthopsetta Gill, Proc. Ac. Nat. Sci. Phila., 1862,330. (.SorcUdus.) 

 Metoponops Gill, Proc. Ac. Nat. Sci. Phila., 1864, 198. ( Cooperi ■■= Sordidus. ) 



Type: Citharichthys cayennensis Bleeker = Citharichthys spilopterus 

 Giiuther. 



This genus iucludes small flounders of weak organization, especially 

 characteristic of the sandy shores of tropical America. The subgenus 

 Orthopsetta includes species of more northern range and somewhat dif- 

 ferent inform, and especially noteworthy as having an increased num- 

 ber of vertebra?,. 



We are not certain that Citharichthys has priority over Orthopsetta, 

 the two having the same ostensible date. 



ANALYSIS of species op citharichthys. 



a. Vertebra} about 40 ; interorbifcal ridge sharply elevated; the head not closely com- 

 pressed ; eyes large. {Orthopsetta Gill.) 



b. Dorsal rays 95 ; anal rays 77 ; lateral line 65 to 70 ; head 3:} in length ; depth 

 2£; eyes large, 3^ in head, the interocular space scaly, concave, 4 

 in eye ; a sharp elevated ridge bounding the lower eye ; mouth not 

 largo; the ■maxillary 3 in head; teeth sharp, subequal anteriorly 

 smaller behind; lower pharyngeals narrow, each with a row of 

 slender teeth; gill-rakers slender, close-set, 7+14; scales large, 

 thin, deciduous, slightly ciliate; numerous accessory scales pres- 

 ent: pectorals long, 1 \ in head; flesh soft. Color dull olive- 

 brownish, the males with spots and blotches of dull orange, the dor- 

 sal and anal blackish, similarly mottled with dull orange; females 

 paler, nearly plain. Vertebra', 11+29 = 40 SORDIDUS, 51.
