This genus differs from Blennius in the restriction of the gill-openings to 

 the sides, the gill-membranes being broadly and fully joined to the isthmus ; 

 canines well developed, (v, upsilon; ithsvpov, side; ^ezAo?, lip; in allu- 

 sion to the V-shaped lateral lips.) 



2734. HYPLEUROCHILUS GEMINATUS (Wood). 



Head 3| to 3|; depth 3 to 4. D. XI, 15 to XIII, 14 ; A. II, 18. Head not 

 very blunt, the anterior profile straight, oblique; male (multifilis) with the 

 supraocular cirrus very large, each with 4 smaller ones at base ; supra- 

 ocular cirrus in female (geminatus) low, shorter than eye, branched at tip j 

 interorbital space concave, not ^ diameter of eye; a slight transverse 

 groove behind eye; canines in both jaws, very strong, hooked backward, 

 the lower considerably stronger than upper ; gill openings extending down- 

 ward to opposite or slightly below lower edge of pectoral. Dorsal fin not 

 emarginate, the spines slender, but rather stiff, lower than the soft rays; 

 pectorals shortish, ventrals rather long. Olive brown, faintly barred with 

 darker ; sides plain, or with several pairs of spots of a reddish-brown color, 

 arranged pretty regularly in a double row ; vertical fins edged with darker, 

 especially the anal ; dorsal black in front. Length 2| inches. South At- 

 lantic and Gulf coast of the United States, in shallow water; abundant in 

 empty shells and clusters of tunicates. The sexes quite unlike, the male 

 (multifilis) distinguished by the high suborbital crest, (geminatus, twin.)
