 (Gen. uov. : type Blennius {lenilHs Girard.) 



This genus differs from BlennitiH in the absence of canine teeth and 

 in the restriction of the gill-openings to the sides, the gill-membranes 

 being fully united to the isthmus as far as the base of the pectorals. 

 The known species are xVmerican. (jVo?, equal; eaOico^ to eat; in allu- 

 sion to the uniformity of the teeth.) (See Addenda.)

 snout steep; supraorbital cirrus large, multifid, as high as eye; inter-
