GENUS ENTOMACRODUS — SPRINGER 



65 



males examined, 1 had 14 rays, 25 had 15 rays, and 15 had 16 rays. Of 

 25 females examined, 1 had 14 rays and 24 had 15 rays. There was no 

 evidence of sexual dimorphism in other meristic characters. The male 

 and female specimens from Samoa each had 16 dorsal rays. 



Nomenclature. — E. epalzeocheilus was described by Bleeker (1859) 

 from a single specimen, 85 mm, from Karangbollong, south coast 

 ( Indian Ocean) of Java. \ have been unable to locate the holotype, but 

 it is clear from the Latin description (especially "vertice cristis ludlis 

 sed poris valde conspicuis longitudinaliter seriatis; nucha utroque 

 latere cirro membranaceo plurifimbriato occulo breviore"), that the 

 specimens considered here are the same species as that described by 

 Bleeker. 



Relationships. — (See also relationships under E. niuajoouensis.) 

 Entomacrodus epalzeocheilus is a member of the E. striatum species 

 group. E. epalzeocheilus differs: from E. niuajoouensis, in having 

 multiple nuchal cirri and in usually having fewer crenulae on the ven- 

 tral margin of the upper lip; from E. randalli, in having more than one 

 pore before each anterior nostril, in having stripes or bands on the 

 upper lip, and in lacking a dark spot in the humeral region ; from E. 

 marmoratus, in usually lacking lateral branches on the main, or longest 

 supraorbital cirrus, in having the nuchal cirri on each side arising from
