blenniidae: salariinae — schultz and chapman 337 



Ecology. — This species was taken with E. thalassinus in the sm^f 

 along the outer edge of the ocean reefs. 



Remarks. — This new species is closest to E. thalassinus, but differs 

 in having the edge of the upper lip crenulate and in having 3 narrow 

 dark streaks across side of head, with a dusky spot behind eye in the 

 first dark streak; the orbital tentacle branches from the base, whereas 

 the upper lip of thalassinus is smooth edged, the side of the head is 

 plain light dusky with a black spot just behind the eye, and the orbital 

 tentacle has chri arising on the inner side of the dermal tentacle.
