transverse one. Dorsal IV, I 11. Anal I 18-19 ; origin in advance of spinous dorsal. 

 Olivaceous ; 2 blackish longitudinal stripes margin the series of scales that runs along 

 the middle of the side ; scattered dark spots below it ; a dark spot at base of each 

 ray of soft dorsal and anal. 



Six specimens, 25 to 37 mm. in total length, from a pond on Moreton Island, near 

 Brisbane, Queensland. 



3. Glossolepis M. Weber, 1907. 

 Nova Guinea, v. p. 241. 



This genus differs from Melanotcenia in the smaller and irregularly arranged scales 

 with deeply crenulated edges and in the longer and more numerous gill-rakers. Also 

 the teeth are stouter and more obtuse than in Melanotcenia. 



A single species. 



Glossolepis incisus. 



M. Weber, Nova Guinea, v. 1907, p. 241, pi. xi. fig. 7. 

 Dorsal IV-VI, I 9-11. Anal I 20-23. 55 to 60 scales in a longitudinal series. 

 About 30 gill-rakers on the lower part of the anterior arch. Reddish brown. 

 L. Sentani, Northern New Guinea. 

 I have examined an example sent to me by Prof. Weber. 



4. Anisocenteus, gen. nov. 



Differs from Melanoimiia only in the structure of the mouth and disposition of the 

 teeth. The lower jaw is included within the upper and has a band of small teeth 

 separated by an interspace from an outer series or double series of enlarged teeth, 

 which are implanted horizontally. The mouth is rather small and its cleft is not 

 very oblique, and is straight or but slightly curved ; the anterior expansion of the 

 prsemaxillaries is scarcely developed. 



A single species. 



Anisocestrus rubrosteiatus. (PI. XXXI. fig. 3.)

 Melanotcenia dumasi M. Weber, Nova Guinea, v. 1907, p. 240, pi. xi. fig. 1, and ix. 1913, p. 558. 

 Depth of body 2f to 3 in the length, length of head 3f to 4§-. Snout longer than 

 distance from its tip to end of maxillary, about as long as diameter of eye, which is 3 j 

 to 3f in length of head ; interorbital width 2^ to 2| in length of head. Cheek with 

 1 or 2 series of scales. 14 to 16 gill-rakers on lower part of anterior arch. 33 to 36 

 scales in a longitudinal series, 11 to 14 in a transverse series, 15 to 20 in front of 

 spinous dorsal. Dorsal (IV) V-VII, I 9-11 (12) ; origin of spinous dorsal equidistant 

 from end of snout and base of caudal, or nearer the one or the other, behind, above, or 

 a little in advance of origin of anal ; first spine -| to f length of head. Anal I 18-21.
