Group BLENNIOIDEA. 
Body more or less elongate, naked or with scales, large or small; ventral tins small, more or less 
advanced in position, often wanting, the number of soft rays always fewer than 5; hypercoracoid per- 
forate, the shoulder-girdle normally formed; skull not armed with spines; suborbital not developed 
as a bony stay articulating with the preopercle; pseudobranchiae present ; dorsal fin long, its anterior 
half and sometimes the whole fin composed of spines; anal long; tail homocercal, the caudal usually 
rounded, rarely forked; vertebrae numerous, especially in the Arctic species. 
A large group, with ill-defined boundaries, the more primitive forms showing affinities with the 
Trachinoidea, Cirrhitidx, and other more typical fishes, the extremes very aberrant and passing directly 
into the Ophidoidea, and other forms lacking spines in the fins. 
Family XCV1. BLENN1ID4I. — Blennies. 
Body oblong or elongate, naked or covered with moderate or small scales, which are ctenoid or 
cycloid; lateral line variously developed, often wanting, often duplicated; mouth large or small, the 
teeth various; gill-membranes free from isthmus or more or less attached to it; pseudobranch ite present; 
ventrals jugular, or subthoracic, of one spine and 1 to 3 soft rays, often wanting; dorsal fin of spines 
anteriorly, with or without soft rays; anal tin long, similar to soft dorsal; caudal well developed; 
vertebrpe in moderate or large number, 30 to 80; hypercoracoid (or “scapula”) perforate, shoulder- 
girdle normally formed; suborbital without bony stay. 
Fishes of moderate or small size, mostly living near the shore in the tropical and temperate or 
Arctic seas; most of them carnivorous, the Clinintx, so far as known, ovoviviparous, the rest viviparous. 
a. Clininse: Body scaly; lateral line high anteriorly. Species ovoviviparous, so far as known Enneapterygius, p. 495 
an. Body scaleless; teeth comb-shaped, in a single row; vomer and palatines toothless or nearly so; lateral line usually 
arched in front; soft dorsal about equal to spinous. Species viviparous. 
b. A short, stout fang-like canine on each side, at least in lower jaw. 
c. Dorsal fin entire; gill-openings wide, the membranes free from the isthmus Blennius, p. 496 
cc. Dorsal fin divided; gill-openings narrow; posterior canines present ..Alticus, p. 497 
bb. No fang-like canines in either jaw. 
d. Blenniinse: Teeth all fixed, attached to the bones of the jaws; dorsal and anal joined to the caudal; carnivo- 
rous Enchelyurus, p. 500 
dd. Salariinze: Teeth all movable, implanted on the skin of the lips; no posterior canines; herbivorous. 
e. Body elongate; D. xur, 22; A. 25 Salarias, p. 501 
ee. Body short; D. xi, 13; A. 15 Exallias, p. 503 
Genus 245. ENNEAPTERYGIUS Ruppell. 
Body rather robust, covered with moderate ctenoid scales; lateral line incomplete; mouth moder- 
ate, the jaws equal; no tentacle on nape; no hook on shoulder-girdle; eye large; dorsal fin divided into 
3 fins, the first of 3 or 4 slender spines, the second of 10 to 24, the soft dorsal of 7 to 15 rays; caudal 
rounded; anal fin long; pectoral long, the lower rays simple and thickened. This genus differs from 
Tripterygion Risso, as typified by the Mediterranean species, T. tripleronotus, in the shorter jaws, the 
presence of a cirrus above the orbit, and in the larger scales. The lateral line is always incomplete. 
Small fishes of the rock pools of the Tropics, found in most warm seas.
