aligned in 7-10 more or less vertical rt)\vs correspondino- to the lip 

 stripes of E. nigricans and E. textilis. The underside of the head 

 may bear several dark or dusky chevrons. 



The anal fin membrane is uniformly dusky anteriorly, but the 

 duskiness becomes separated posteriorly into two portions by a pale 

 diffuse stripe. The anal rays are dark distally but become paler 

 proximally, except for a slight, diffusely pale-dusky sub-basal stripe. 

 The caudal fin bears three to six irregular dark bands, depending on 

 the length of the specimen (the longer the specimen, the more the 

 bands). The pectoral is dusky, though much paler dorsally; there 

 may be on the fleshy pectoral base one or a few dark blotches sepa- 

 rated by a pale cresentic mark. A dusky area, also on the fleshy 

 pectoral base, is proximal to the pale area. The pelvic fins vary from 

 pale to dusky. 



In general, males are more uniformly colored than females, but 

 there are exceptions.
