Ctenogohius candidianus. 



Depth of body 5 in the length, length of head 3^, to 3f. 

 Snout dccuived, nearly twice as long as the eye, the diameter 

 of which is 5 in the length of head ; jaws equal anteriorly ; 

 mouth little oblique. Opercles naked ; nape covered with small 

 scales. Dorsal VI, I 8. Anal I 8. None of the rays of the 

 spinous dorsal produced ; soft dorsal and anal rather low. 

 Caudal rounded. Pectoral a little shorter than the head ;

XXV. — Descriptions of Four new Freshwater Fishes from 

 British New Guinea. By C. Tate ReGAN, M.A. 



The freshwater fishes of New Guinea have recently been 

 made the subject of an extensive memoir by Prof. Max 

 Weber (Exped. Sci. Neerland. Nouvelle-Guin«e, v. Zool. 

 1907). A small series from British New Guinea brought 

 home by Dr. Seligmann is of some interest, inasmuch as it 

 contains examples of four species which appear to be new to 

 science and of three others not included in Max Weber's 

 list; the latter are Sicydium cynocephalum, C. & V., and 

 Eleotris toinioptera, Blkr., from the Wedau lliver, and 

 Eleotris compressa, KrefFt, from Agajambo. The fishes are 

 from four localities, those from the Wodau River and the 

 Fly River having been presented to the British Museum by 

 Major W. Cooke Daniels, those from Agajambo by V. A. W. 

 Monckton, Esq., and those from Sogeri by Ca[)tain F. R. 

 Barton.
