Text Appearing Before Image: ACANTHOPTERYGII 689 Fam. 1. Gobiidae.—Suborbital arch ligamentous or absent. Gill-membranes more or less broadly attached to isthmus; 4 to 6 branchiostegal rays; gills 4, a slit behind the fourth; pseudo- branchiae often present. All or most of the praecaudal vertebrae with transverse processes bearing the ribs, to which epipleurals are attached. Post-temporal forked, as in normal Perciformes. Ventral fins with 1 feeble spine and 4 or 5 branched rays, often united to form a sucking disk, a transverse fold of skin at their base completing the cup. Head usually more or less depressed, body varying from short and stout to elongate and eel-shaped, but never with a very high number of vertebrae, these varying from 24 to 37 (10-14 4-1-3-24); scales cycloid or ctenoid, or absent; no lateral line; mouth moderate or large, dentition various; soft dorsal and anal fins nearly equally developed, varying from very short to very elongate; usually a large anal papilla. Text Appearing After Image: Fig. 420.—Gobius ruthensparri. Nat. size. (From Holt and Byrne, P^eport Fisheries Irelo.ndfor ]901.) A large family of some 600 species, the great majority marine, mostly carnivorous and of small size. The largest form {Eleotris marmorafa, from the rivers of Siam, Borneo, and Sumatra) grows to nearly 3 feet, whilst the smallest {MisHchthys luzonensis, from the Philippines) measures only 12 to 14 millimetres, and is believed to be the smallest known Vertebrate. Gobiids occur in all the seas outside the Arctic and Antarctic circles, and they have representatives in the fresh waters of all parts of the world. The genera are numerous but difficult of definition. The following are the principal: JEhotris, 0:ri/vietopon, Vireosa, Rhyacichthys,'Oo'bius, CrystallogoUus, Aphia, GoUosoma, Gohiodon, Benthophilus, TypUogoUus, LuciogoUus, Sicydium., Zentipes, Peri- ophthalmus, Boleophthalmus, .AmUyopus, Trypauchen, Trtjpau- VOL.
