but which not unlikely came from the East Indies. Nemipterus mac- 

 ronemns iigrees very closely with Xemlpterns nemdiophorns Giinther, 

 from Sumatra. According to ]ilcekcr the chief dillerencos are these, 

 that in macronemus but one dorsal spine is fdamentons, in nematophorun 

 two; in Macronemus the lins are more i)ointed. All these are doubtful 

 characters and it is i)robable that Xcmipternn macronemus came from 

 Sumatra rather than from Surinam. 



Subfamily VI.— SPARINiE. 

 XXII. STENOTOMUS. 



Stenotomus Gill, Canadian Naturalist, August, 1865 {(trgnrnpit). 



Type: Sparus argyrops Linnanis = 8paruH chrysops Linnreus. 



Etymology: (7riK(5^, narrow; tojio:^ (jutting; from the narrow incisors. 



This genus contains, so far as known, three species, all American; 

 one lives in rather deep water and differs considerably from the others. 

 The genus is close to Calamus, from which the Ihittened incisors mainly 

 distinguish it.
