1.8 in head and equal to its postorbital part. Colour faded, 

 uniform brown. Fins uniform. Length 50 mm. 



Habitat: Perak. 



Note. We found in the collection of BLEEKER in the Leiden 

 Museum in a bottle containing numerous specimens of Betta 

 and named by BLEEKER B.picta the above described species. 

 We are not sure that it is really B. bellica Sauv. as its des- 

 cription by SAUVAGE is very short and the accompanying 

 figure probably not very good, but our specimen comes nearest 

 to this species. 



Doubtful species. 

 Betta pugnax (Cant.). 



Macropodus pugnax Cantor, Cat. Malayan Fishes, Journ. Asiat. Soc. Bengal 

 vol. XVIII. 1850, p. 1066. 



This species is mentioned by the following authors from 

 different localities in the Archipelago: by VON MARTENS ') 

 (Borneo: Seminis); KAROLI 2 ) (Borneo: Palandok, Matang) ; 

 BOULENGER 3 ) (Sumatra: Deli); VAILLANT 4 ) (Borneo: rivers 

 Kapuas, Knapei, Sebruang, Mahakam) ; VOLZ 5 ) (Sumatra: 

 Palembang, Benakat, Lahat, rivers Mahe, Kwantan, Si Russi 

 and at Indragiri, Tandjung Butusand Upper and Lower Langkat); 

 FOWLER G ) (Borneo : Baram river). 



All the quoted authors give no description and as their 

 publications appeared before the valuable revision of the genus 

 Betta by TATE REGAN, who mentions as habitat for B. pugnax 

 only Pinang, it is impossible to make out what species is meant 

 by the quoted authors. PERUGIA 7 ) gives a very short description 

 of specimens found in Sumatra and named by him B. pugnax, 

 but these specimens probably belong to B. picta (C.V.). Also 

 the description of STEINDACHNER 8 ) of specimens, which he
