Trichopharynx Ogilby, Proc. Linn. Soc. N. S. W. 1897, 769 [crassilahris). 

 Thia 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 j)robable that the generic name Awaons should be adopte^l for this grouji, on the strength of its use 

 in a subgeneric sense by Steindachner.

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 Giinther'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.

 Oabius crassilabris Giinther, Fische der Sudsee, 178, 1873, Oualan, Aneiteum. 



This species is common in the streams of Malanesia. It was ncjt taken by us. It resem))Ies 

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

 guaiiiensis.

This East Indian sjiecies, not seen by us, resembles an Awaous, although ligureil as having the 

 cheeks fullv scaled. 



AMBLTGOBIUS Bleeker. 



AmUygohius Bleeker, Arch. Neerl. 1875, 322 {sphinx). 

 Odonlogohius 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, Pterogohhis, are cross-banded. 

 We can see no generic differences separating Odontogobius from Amblygobius.
