bases of the pectorals and that it belongs to the genus Glyptosternum. 

 Further investigations showed it to belong to G. platypogon (C. Y.), a 

 rather common species from mountain streams and rivers of Java, Su- 

 matra and Borneo. 



Callomystax schmidti has therefore to stand as a synonym of G. pla- 

 typogon (C. V.). The other members of the genus Gagata live in rivers 

 of British India and Burma, so that the genus disappears from the list 

 of Indo-australian fishes. 



The range of the genus, curiously discontinuous as long as it was 

 believed that a species occured in Sumatra, is now quite comprehensible. 



6. On Stiphodon elegans (Steind.). 



One of us (de Beaufort, Bijdragen tot de dierkunde, Afl. 19, 

 1913, p. 143) expressed the opinion, that the Gobiid Sicydium elegans 

 Steindachner (Sitzber. Akad. "Wien LXXX. 1879, p. 152) from the 

 Society Islands was the same as Stiphodon semoni Max Weber (Semon, 

 Forschungsreise v. 1895, p. 270) from the indo-australian Archipelago. 

 We compared typical specimens of lastnamed species with Steindach- 

 ner' s types in the Vienna Museum and could find no differences 

 between the two.
