We have 23 specimens from Vaisigano River and 8 from Vailima brook and tributaries near Apia, 

 2 specimens from Gasegase River at Vaimosa near Apia, and 42 specimens from the stream at Pago

1442. Vaimosa notospila (Giinther). Streams of Fiji. 



Gobius notospilits Giinther, Fische der Siidsee, 173, taf. 110, fig. e, 1873, Namusi in Viti Levu (Fiji). 



OPLOPOMUS Steindachner. 

 Centrogobius Bleeker, Arch. Neerl. 1875, 321 (nutacanthus); not Oplopoma Girard. 

 This genus is characterized by the presence of a small spine on the preopercle. The dorsal spines 

 are rigid. In other respects it resembles lihinogobius. 



1443. Oplopomus oplopomus (Cuvier & Valenciennes). Tahiti; East Indies. 



Gobius oplopomus Cuvier & Valenciennes, Hist. Nat. Poiss., xn, 66, 1839, Red Sea. Giinther, Fische der Siidsee, 170, 



Philippines, Macao, Tahiti. 

 Gobius bitelatus Cuvier & Valenciennes, Hist. Nat. Poiss., xn, 89, 1839, Red Sea. 

 Gobius notacanthus Bleeker, Goram, 110, Goram. 



ABOMA Jordan & Starks. 



Aboma Jordan & Starks, Proc. Cal. Ac. Sci. 1895, 497 (etheosloma) . 

 This genus differs from Rhinogobius in the presence of 7 dorsal spines. 



1444. Aboma graeffei ( Giinther). Rivers of Fiji. 



Gobius grseffei Gunther*, Fische der Siidsee, 179, Viti Levu, in fresh water. 

 This species unknown to us is recorded by Gunther and Kner from the streams of Fiji. 



PARAGOBIODON Bleeker. 

 Paragobiodon Bleeker, Arch. Neerl. 1875, 309 (melanosoma) . 

 This well-marked group is distinguished' by the very cKicby body, subglobular head, short cup- 

 shaped ventrals, and by the presence of numerous short prickles or filaments on the head. The scales 

 are large, the sides of the head naked and the fins short. The lower jaw has 2 small canines. The 

 resemblance of these species to Gobiodon indicates no close affinity.
