AMBLYGOBIUS Bleeker 
(Odontogobius Bleeker.) 
257. Amblygobius phaleena (Cuvier & Valenciennes). 
Colors in life: Dark green, the body with five light and five dark alternate bands, between each two 
of which is a narrow light blue band; three blue stripes on gill cover; a large dusky spot above upper 
angle of opercle; a similar spot on upper part of tail near base; first dorsal striped with cream and brown, 
a large dusky spot on its posterior portion; second dorsal margined with light yellow, blue black, and 
brown; belly pale blue; anal pale blue, like belly, margined with dusky; ventrals very pale blue, with 
dusky margins; pectoral clear pale yellow; caudal washed with salmon, dusky at tip. 
A single specimen, 2 inches long, from Cagayancillo. 
GOBIICHTHYS Klunzinger. 
(Pselaphias Jordan & Seale.) 
258. Gobiichthys tentacularis (Cuvier & Valenciennes). Zapatero. 
Two specimens from Iloilo, 3 inches long, and one of the same size from Aparri, northern Luzon. 
The genus Gobtichthys Klunzinger (petersii)) supersedes Pselaphias Jordan & Seale, the type of 
Klunzinger’s genus having a tentacle over the eye. Except in this rather slight character, Gobiichthys 
does not differ from Oxyurichthus Bleeker as restricted in the present paper. 
OXYURICHTHUS Bleeker. 
The genus Oxyurichthus Bleeker (belosso) includes gobies with ventral fins united, tail lanceolate, 
dorsal fin short, an adipose nuchal crest, the upper teeth in one series, and the tongue convex. The 
species differ from those of Gobiichthus Klunzinger (Pselaphias Jordan & Seale) in lacking a tentacle over 
the eye, and from Gobionellus Girard in having the upper teeth in a single series, and the tongue convex. 
The type of Oxyurichthus was stated by Bleeker to have the upper pectoral rays silk-like, doubtless by 
error, none of the closely related forms of these genera known to us having them so. Gobius papuensis 
Cuvier & Valenciennes and Gobionellus lonchotus Jenkins are congeneric with the present species. 
259. Oxyurichthus cristatus (Day). 
A single specimen from Cagayancillo, 3 inches long. 
APARRIUS Jordan & Richardson, new genus. 
Aparrius Jordan & Richardson, new genus of Gobiidize (acutipinnis. ) 
This genus has the teeth very fine, in bands in both jaws, the tongue short, adnate nearly to tip, 
emarginate, and the tail acuminate, as in Gobionellus, in each of these characters differing from Rhino- 
gobius. Like Rhinogobius, it has the scales large and the soft dorsal fin short. The name is from Aparri 
in northern Luzon, where the typical species is found. 
260. Aparrius acutipinnis (Cuvier & Valenciennes). 
Gobius acutipinnis Cuvier & Valenciennes, Hist. Nat. Poiss., x11, 80, 1837; Malabar. Day, Fishes India, 292, pl. LX1, fig. 2, 
1878-88; Seas of India to the Andamans. 
Rhinogobius ocyurus Jordan & Seale, Bul. U. S. Fish Comm., xxv1, 1906, 42, fig. 14; Cavite, P. 1. 
Acentrogobius acutipinnis, Smith & Seale, Proc. Biol. Soc. Wash., X1x, 1906, 81; Mindanao, P. I. 
Head 3.60; depth 4; dorsal yr-11; anal 11; scales 27; hose 3.50; maxillary 2; interorbital space .66 
of eye; eye 4; teeth very fine, in bands in both jaws; outer teeth not enlarged; no canines; tongue short, 
adnate nearly to its tip, which is emarginate; cheeks and opercles naked; nape scaled, at least posteriorly; 
maxillary nearly to back of orbit; mouth scarcely oblique; first four rays of spinous dorsal (in female) 
prolonged, though scarcely filamentous, carrying the membrane nearly to their tips; the depressed 
longest spinous ray reaching to fourth ray of soft dorsal; soft dorsal high behind, the depressed fin reaching 
past base of caudal; caudal long, acuminate, its length less than 2.50 in length without caudal; anal 
reaching base of caudal; ventrals united, reaching nearly to vent; pectorals slightly Ionger than head, 
without silk-like rays.
