of the unpaired fins. Stegastes , in the sense used by Bleeker (non Jenyns), included 
Glyphidodon lacrymatus, G. leucozona , G. batjanensis, and G. dicJcii, all of which have 
13 or 14 longitudinal rows of body-scales and the suborbital and inferior preopercular 
limb scaly. Fowler & Bean, 46 following Bleeker, added Abudefduf azurepunctatus 
to this group. 
Jenyns however stated that vomerine and palatine teeth are present in 
Stegastes , and this feature, combined with the different shapes of the unpaired fins, 
and the denticulated preoperculum, shows that Stegastes cannot be applied to the 
very different Glyphisodontine forms. 
I accordingly propose the new generic name Negostegastes for Glyphisodon 
leucozona Bleeker and its allies mentioned by Bleeker, including also Abudefduf 
azurepunctatus Fowler & Bean. J
