The geuiLs Flatj/glossus, as left by Giiutber, does uot ap])ear to reijnire 

 auy further subdivisiou. The American species are certainly all very 

 closely related and belong to the same group, apparently that called 

 JIalichwres by EUppell and Bleeker, and Chccyqjulishy Gill. We have 

 not exauiined any specimens of the groups called Platyfjlos.sus, Macro- 

 pharyugodon^ Giintheria, and Hemitauioga ;. but as Giiuther lays no 

 stress on the distinctions pointed out by Dr. Bleeker, they are probably 

 of iusignilicant value. If these subordinate groups are regarded as 

 genera the American species are all referable to Chcerojnlis, distin- 

 guished from GUntheria Aud Hemitautogahy the naked head, from Platy- 

 glosKUshy the absence of a scaly sheath at base of dorsal and anal, and 

 from Macropharyngodon perhaps by the form of the pharyngeals. With- 

 out further information as to the East Indian species we cannot admit 

 thejse nominal genera. 



The geueric names, Chlorichthys and lehfhycallus of Swainson, based 

 iu part on species of Platyglossus, but distinguished by imaginary char- 

 acters, and including species of earlier genera, have been very properly 

 set aside by Dr. Gill as synonyms of Coris aiidJuUs.
