XI. ATHERINO'SOMA 27 



14. Glossolepis incisus Weber, 1908. 



Glossolepis incisus Weber, Nova Guinea, 5, 241, pi. 11, fig. 7, 1908; 9, 562, 1913; 

 Regan, Trans. Zool. Soc. London, 20, 281, 1914. 

 Type-locality. — Lake Sentani, northern New Guinea. 

 Range. — Lake Sentani, New Guinea. 



X. RHADINOCENTRUS Regan. 



Rhadinocentrus Regan, Trans. Zool. Soc. London, 20, 280, 1914. 



Orthotype. — Rhadinocentrus ornatus Regan. 

 Range. — Fresh waters of Queensland. 



In the lack of pungent spines in the fins, and in other characters, 

 the genus Rhadinocentrus approaches the three which follow, Atheri- 

 NOSOMA, PsEUDOMUGiL, and Telmatherina. This and related genera 

 differ from these three in much the same manner that Thyrina differs 

 from Menidia ; the belly is shortened, the anal fin elongate, with the 

 origin anterior. 



15. Rhadinocentrus ornatus Regan, 1914. 



Rhadinocentrus ornatus Regan, Trans. Zool. Soc. London, 20, 280, pi. 31, fig. 1, 

 1914; Cockerell, Mem. Queensl. Mus., 3, 38, 1915; Ogilby, Mem. Queensl. Mus., 

 6, 99, 1918. 

 Type-locality. — A pond on Moreton Island, near Brisbane, Queensland. 



Range. — Fresh waters of Moreton Island, Queensland. 



XI. ATHERINOSOMA Castelnau, 1875. 



Atherinosoma Castelnau, Researches Fishes Australia, 138, 1875; Macleay, Proc. 

 Linn. Soc. N. S. Wales, 6, 45, 1881 (1882) ; 9, 171. 1884 (1885). 

 Haplotype. — Atherinosoma vorax Castelnau. 

 Range. — Australia ; probably confined to fresh water. 



Atherinosoma has teeth on the jaws and vomer, and according to 

 the type description, there are also teeth, strong and hooked, on the pala- 

 tine and tongue. The body is moderately elongate ; the first dorsal in- 

 serted well forward, its spines filamentous ; the anal short ; the scales 

 very large, as in Pseudomugil. 



This genus is imperfectly known, but the discovery and description 

 of a second species seem to indicate that the genus is valid and that 

 its relationships are closest with Pseudomugil. 



16. Atherinosoma vorax Castelnau, 1872. 



Atherinosoma vorax, Castelnau, Proc. Zool. Soc. Victoria, 1, 138, 1872; Macleay, 

 Proc. Linn. Soc. N. S. Wales, 6, 45, 1881 (1882). 

 Type-locality. — Cape Schanck, Australia. 

 Range. — Region of Cape Schanck. Australia ; perhaps in fresh water.
