1190. MUGIL TRICHODON, Poey. 

 (FAN-TAIL MULLET.) 



Head 4 ; depth 3f. D. IV-I, 8; A. Ill, 8; scales 33-11. Body rather 

 robust, its depth somewhat greater than in Mugil curema. Snout rather 

 narrow and pointed, the upper and lower profile about equally oblique. 

 Interorbital space flattish or slightly convex, 2^ in head. Upper lip 

 thick, thicker than in any other species here described. Space at the 

 chin between the mandibulary bones oblanceolate, acutish posteriorly. 

 Preorbital narrow, covering little of maxillary. Eyes hidden anteriorly 

 and posteriorly by a broad adipose membrane. Teeth wide-set ; larger 

 than in most other species ; plainly visible in both jaws, and about as long 

 as the nostril. Scales large, about 21 from origin of dorsal to tip of 

 snout; soft dorsal and anal densely scaled. Soft dorsal concave; the 

 seventh ray shortest, 2| in second or longest ray ; anal similar to soft 

 dorsal. Pectoral not reaching nearly to front of spinous dorsal. Caudal 

 broad, forked. Color dusky olive above, with some bluish reflections; 

 silvery below. No dusky streaks along the rows of scales. A dark blotch 

 at base of pectoral. Dorsals and caudal pale, the former with very small 

 dark punctulations. Caudal margined with blackish. Anal and ventrals 

 yellowish. Pectorals pale, finely punctulate with brown. Length 10 

 inches. Florida Keys to Brazil; very abundant at Key West, but rare 

 about Cuba. (&pi%, hair; bdovc, tooth.)

Cleft of mouth lateral ; lower jaw narrow ; dentiform cilia in very many 

 series, broad, flat, and somewhat paved ; upper lip very thick ; no adi-

1191. CHJENOMUGIL PROBOSCIDEUS* (Giinther). 



Head, and especially the body and tail, compressed ; the greatest depth 

 of body nearly equals length of head, and is 4-J in total length ; eye 4, 

 shorter than snout. Dorsal IV-I, 8 ; anal III, 10 ; scales 38, 14 in trans- 



* A second species of Chsenomitgtt, possibly American, is Chsenomugil nigro-strigatiis (GUNTHER): 

 Head 5; depth 4%; dorsal IV-T, 8; anal III, 9, scales 42, 13 or 14 in a transverse series, 27 

 between snout and spinous dorsal. Upper lip extremely thick, without transverse fold, and with 

 about 7 series of small flat papillae on its inferior half; lower lip with a broad membranaceous 

 margin, notched in the middle, but not ciliated. Interorbital space slightly convex, 2% i n head. 

 Snout as long as eye or longer. Chin nearly entirely covered by the mandibles. Preorbital 

 truncate, not notched, not covering extremity of maxillary. Pectoral inserted nearly in the 

 middle of the depth of the body, without a pointed scale in its axil; not quite as long as head,
