Mugil capita Cuvier {ceur ForskSl) may be taken as the type. Some of 

 the species of Liza approach in dentition to GlicenomugU, and it is possi- 

 ble that the two groups will be found to intergrade. 



Besides the species mentioned below, a species with elongate pec- 

 torals, as yet undescribed, has been obtained by Prof. Charles H, Gil- 

 bert at Panama. Unfortunately all the known examples of this species 

 have been destroyed by fire. 



ANALYSIS OF AMERICAN SPECIES OF MUGIL.* 



a. Eye with a well- developed adipose membrane (subgenus MuGiL). 



6. Soft dorsal and anal fins almost naked ; anal rays, iii, 8 ; sides with dark lon- 

 gitudinal stripes along the rows of scales; caudal deeply forked; 

 size large. 

 0. Scales about 33 in a longitudinal series ; depth about 4^ in length to base of 

 caudal ; teeth very minute ; distance from tip of pectoral to front 

 of dorsal about two-sevenths the length of the pectoral ; lips rather 



thin Liza, 1. 



ce. Scales about 40 in a longitudinal series ; depth about 4 in length to base of 

 caudal ; teeth close set, rather small ; distance of tip of pectoral 

 from front of dorsal about two-ninths length of pec- 

 toral Cephalus, 2. 



lib. Soft dorsal and anal fins scaly ; sides without dark stripes along the rows of 

 scales ; caudal less deeply forked ; size smaller. 

 d. Anal rays, iii, 9 ; scales .35 to 45 in a longitudinal series. 



e. Scales 42 to 45 in a longitudinal series ; teeth small, hair-like ; lips rather 



thin Incilis, 3. 



ee. Scales 35 to 38 in a longitudinal series. 

 /. Pectoral nearly reaching origin of dorsal ; the distance from tip of pec- 

 toral to front of dorsal about one-sixth the length of the pectoral ; 

 teeth rather wide set, very small, scarcely visible without a lens 

 in the adult ; larger in the young ; scales 35 or 36 in a longitudinal 



series Gaimardianus, 4. 



ff. Pectoral not nearly reaching origin of dorsal ; the distance from tip of 

 pectoral to front of dorsal being in the adult about one-sixth 

 length of pectoral ; teeth close set, rather small (but distinctly vis- 

 ible without a lens) ; scales 38 or 39 in a longitudinal se- 

 ries CUREMA, 5. 



dd. Anal rays, iii, 8,- scales very large, about 33 in a longitudinal series; 

 teeth wide set, larger than in any other species, about as long as 

 the nostril ; upper lip thick ; pectoral not nearly reaching front of 

 dorsal ; size small Brasiliensis, 6.
