THE FISHES OF SAMOA. 405 



Chonophorus Poey, Syst. Gob., 320 1874, (bucculentus— banana). 



Awaous Bleeker, Rev. Gob., 320, 1875 (ocellaris). 



Trichopharynx Ogilby, Proc. Linn. Soc. N. S. W. 1897, 769 (crassilabris). 

 This genus contains large gobies of the tropical rivers, characterized by a peculiar physiognomy, 

 and by the presence of small fleshy flaps on the shoulder-girdle; tongue adnate to floor of mouth. It 

 is probable that the generic name Awaous should be adopted for this group, on the strength of its use 

 in a subgeneric sense by Steindachner. 



1465. Awaous stamineus (Valenciennes). Hawaii. 



1466. Awaous ocellaris (Broussonet). Mano'o; I' a pala. Tahiti; Samoa; Earotonga; Fiji, in 



streams. 

 Gobius ocellaris Broussonet, Dec. Ichth., pi. 142. 1782, Tahiti, coll. Solander. Cuvier & Valenciennes, Hist. Nat. 

 Poiss., xii, 98 1837, He de France. Gunther, Fische der Siidsee, 177, taf. 108, rig. c, Samoa, Rarotonga, Viti Levu. 



We have 2 specimens from the stream at Pago Pago and 20 specimens of various sizes from the 

 Vaisigano River at Apia. The species is common in the river where the current is broad and swift. 

 It reaches a length of 6 inches. There are scales on upper edge of cheeks and opercles, not on the 

 whole side of head as shown in Gunther's figure. . 



Life colors of 2 specimens from Apia, called mano'o iapala, mottled green; dorsals and anal red- 

 tinged; a large black ocellus on dorsal; caudal with 2 or 3 black bars; soft dorsal with 3 black bars; 

 anal reddish, pale-edge; ventral reddish. Adult males nearly black with black lower fin. 



1467. Awaous crassilabris (Gunther). Rivers of Oualan; Aneiteum; Shortland I. (Seale). 

 Gobius crassilabris Gunther, Fische der Stidsee, 178, 1873, Oualan, Aneiteum. 



This species is common in the streams of Malanesia. It was not taken by us. It resembles 

 Awaous ocellaris, but lacks the black ocellus on the dorsal. It may not be different from Awaous 

 guamensis. 



1468. Awaous guamensis (Cuvier & Valenciennes). Guam. 



Gobius guamensis Cuvier & Valenciennes, Hist. Nat. Poiss., xii, 103, 1837, streams of Guam. Sauvage, Bull. Sci. 

 Phil. 1879, 7, Guam. 



1469. Awaous genivittatus (Cuvier & Valenciennes). Teli. Rivers of Hawaii; Fiji; Samoa; 



Tahiti; New Hebrides. 

 Gobius genivittatus Cuvier & Valenciennes, op. cit., 64, 1837, Tahiti. Gunther, Fische der Stidsee, 170, taf. 910, fig. c, 

 Tahiti, Fiji, Samoa, Hawaii. 



Abundant in the quiet pools and sluggish reaches of the Vaisigano and other rivers. We have 5 

 specimens from Vaisigano River. 



EXYEIAS Jordan & Seale, new genus. 

 Exyrias Jordan & Seale, new genus of Gobiidse {Gobius puntangoides Bleeker). 



1470. Exyrias puntangoides (Bleeker). Ponape; Shortland I. (Seale); Cebu. 

 Gobius puntangoides Bleeker, Nat. Tijd. Ned. Ind., V, 1853, 242. 



This East Indian species, not seen by us, resembles an Awaous, although figured as having the 

 cheeks fullv scaled. 



AMBLYG0BIUS Bleeker. 



Amblygobius Bleeker, Arch. Neerl. 1875, 322 (sphinx). 

 Odontogobius Bleeker, Arch. Neerl. 1875, 323 (bynoensis). 

 This genus is distinguished by the small scales, the robust form, and the presence of strong canines 

 in the lower jaw. The species, like most of those of the related genus, Pterogobius, are cross-banded. 

 We can see no generic differences separating Odontogobius from Amblygobius. 



1471. Amblygobius semicinctus (Kuer). Fiji; Oualan. 

 Gobius semicinctus, Kner, Sitz. Ak. Wiss. Wien, 31, Oualan, Fiji. 



1472. Amblygobius phalsena (Cuvier & Valenciennes). Vanicolo; Samoa; Palau Is.; Tonga; 



Fate (Seale). 



Gobius plialsena, Cuvier & Valenciennes, Hist. Nat. Poiss., XII, 92, 1837, Vanicolo. Gunther, Fische der Siidsee, 178,
