A REVIEW OF THE AMERICAN SPECIES OF MARINE MUGILID^S!. 

 By DAVID S. JORDAN and JOISEPH SWAIIV. 



In the present paper is given the synonymy of the species of Mugilidos 

 known to inhabit the salt and brackish waters of America, with analytical 

 keys by which the species and genera may be distinguished. Five of 

 the species of Mnoil are also described in full. 



The marine Mugilidce of America fall naturally into three genera, which 

 may be thus distinguished : 



a. Anal spiues three; teeth ciliiform, flexible; stomacli muscular, gizzard like. 

 h. Cleft of moutli chiefly anterior; lower jaw broad ; cilia in one or few series. 



MUGIL, 1. 

 lih. Cleft of mouth lateral; lower jaw narrow; cilia in very many series, pave- 

 ment-like ; upper lip very thick; no adipose eyelid; vertical fins scaly. 



Ch^nomugil, 2. 



aa. Anal sjiines two, the first soft ray simj^le, but distinctly articulate; teeth distinct, 



scarcely ciliiform ; lips thin ; no adi^jose eyelid ; vertical fins, not scaly ; stomach 



muscular, gizzard-like Querimana, 3. 



Genus 1. — Mugil. 



Mugil, (Artedi, Genera, 32) Linnaeus, Syst. Nat.,ed. x, 1758, 316 (eephalus). 

 Liza, Jordan & Swain (subgenus nova) (capito). 



The species of the genus seem to fall into two natural groups, the one 

 having the eye largely covered by a transparent adipose eyelid, the other 

 group having the eyelid obsolete. These groups should apparently rank 

 as subgenera. The type of the genus Mugil, M. eephalus, as now un- 

 derstood, belongs to the first of these groups, which should retain the 

 name Mugil. The other group may receive the name of Lisa, a name 

 almost universal among Spanish-speaking people for the different species 

 of mullet, xill the American species belong to the subgenus Mugil, the 

 species of Liza being confined to the Old World. Of the latter group,
