NO. 2294. FISHES FROM WEST AFRICA— FOWLER. 199 



symmetricus . The eye is much larger in T. piduratus and the pec- 

 toral is also slightly longer. The scutes are within the same vari- 

 able limits in both species, my Californian material showing 50 to 

 54+46 to 52, though with rakers apparently slightly more numer- 

 ous, 16+45. The example I recorded from Valparaiso, as the present 

 species is T. symmetricus.^ It has scutes 50+50. 



Scales of all three species are variable, though usually with three 

 basal striae more or less marginal. The circuli are fine, but little 

 coarser on middle of scale. 



The Australian Oaranx declivis Jenyns ^ is shown with broad 

 scutes as in T. fncturatus, 82 in number, with about 50 on drawing 

 as spinescent in straight part of lateral line, though it has a few 

 more soft dorsal and anal rays than any of my examples of T. pic- 

 turatus. Bowdich originally published a wretched figure and his 

 description says soft dorsal with 17 and anal with 15 rays.^ 



CAESIOMORUS GLAUCUS (Linnaeus). 



Head, 3| to 4; depth, 2^ to 2i; D. VI— I, i, 25, once 24; A. II— 

 I, r, 23 to 25; snout, 3| to 3 J in head; eye, 4 to 4|; maxillary, 2f to 

 2f; interorbital, 2| to 3; scales, 127 in lateral line to caudal base 

 and 4 more on latter. Body well compressed, contour evenly fusi- 

 form. Caudal peduncle compressed, depth ^ to f its length. Pre- 

 dorsal keel forward till over nostrils. Head compressed, sides about 

 evenly approximate above and below. Snout conic, long as wide 

 or length four-fifths of width. Eye round, advanced, hind edge 

 midway in head length and adipose lid around edges. MaxiUary 

 shghtly beyond eye front, expansion 2^ to 2f in eye. Mouth oblique, 

 jaws about even. Teeth minute, in narrow bands, resolving into 

 1 or 2 irregular narrow rows along sides of jaws. Narrow band of 

 very minute teeth, and similar ones in small arrow-shaped line on 

 vomer. Nostrils small, together, about two-thirds of eye diameter 

 before eye and level with its upper edge. Least infraorbital width 

 sUghtly over one-fourth to one- third of eye. Rakers 14 to 16 + 

 28 to 31, lanceolate, slightly longer than filaments. Scales cycloid, 

 rounded, largest along lateral line opposite soft dorsal and anal. 

 Patch of scales on front of cheeks behind maxillary, and another 

 behind eye, head otherwise naked. Spinous dorsal begins little 

 nearer soft dorsal origin than hind eye edge, spines low, second to 

 fourth subequaUy longest or about 1^ to 1| in eye. Soft dorsal 

 inserted about midway between snout tip and eye, or little nearer 

 caudal base, front of fin elevated though not as lobe and first branched 

 ray If to If in head. Soft anal similar, only first branched ray li- 

 te 2^ in head. Caudal very deeply forked, long slender pointed
