NO. 3582 GENUS ENTOMACRODUS — SPRINGER 61 



species of Entomacrodus and there is no benefit to be derived from usino; 

 it otherwise. In any event, Blennius mannoratus is the oldest name 

 available for any species of Entomacrodus and it matters not to 

 Bennett's honor to which species it is applied. Let it therefore accrue 

 to a Hawaiian species. 



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

 Entomacrodus marmoratus is a member of the E. striatus species group. 

 E. marmoratus differs: from all other members of the group most 

 obviously, in ha\dng the nuchal cirri on each side arising from two 

 bases; from all but E. striatus, in having both lateral and mesial 

 branches on the main supraorbital cirrus (more cirri at a given size) ; 

 and from E. epalzeocheilus and E. niuafoouensis , in ha\'ing only one 

 pore before each anterior nostril. 



Distribution (fig. 6). — E. marmoratus has been taken only from 

 the Hawaiian Islands, where it has been collected with the only other 

 species of Entomacrodus occurring there, also an endemic, E. strashurgi. 

 It differs from E. strashurgi in having more supraorbital cirri, nuchal 

 cirri, gill-rakers, pseudobranchial filaments, and crenulations on the 

 upper lip. Strasburg (1956) reported that E. marmoratus abounds in 

 areas of heavy surf occurring along rocky shores. It has also been 

 taken from tide pools, and the larvae have been taken from imder a 

 light offshore.
