146 FRESH AND BRACKISH WATER FISHES. 



Coloration: yellow with a purple resplendence; a bright 

 silvery band from the orbit to the centre of the caudal fin. 

 Opercle silvery, eye with a black spot at the upper edge. 

 Interspace between the second and third dorsal spine blackish. 



Sub N''. 5140 are preserved the 8 ex., mentioned by 

 Dr. Bleeker in his Atlas Ichthyologique ; yet these speci- 

 mens are much faded. 



It may be observed here, that, after Bleeker's death, 

 the Leyden Museum bought in 1879 the whole collection, 

 made by this eminent ichthyologist for his own study. 

 Together with the fishes, he formerly sent to the Leyden 

 Museum , these collections were the base for all his ich- 

 thyological treatises, especially for his » Atlas Ichthyologi- 

 que des Indes Orientales Neerlan daises". So it is obvious, 

 that all the specimens from Bleeker's collections, repre- 

 senting species founded by him , are typical ones.

N^ 5153. 6 Ex. Length 65—90 mM. 



Except these and the afterwards enumerated 63 ex. from 

 the collections of ten Kate, the Leyden Museum possesses 

 a series of 115 ex. of A, scandens (length 32 — 185 mM.). 

 The number of scales in the lat. 1. is in all these 30 , 

 sometimes 31 , never less. Concerning the form of the 

 body, there is some variation in the proportion between 

 the height of the body and the total length. In intact 

 examples I found the total length varying between the 

 limits 4.3 and 3.06 X greatest height. 



I agree with Bleeker , when he says (Mem. sur les pois- 

 sons a pharyngiens labyrinthiformes , p. 9, Nat. Verh. 

 Kon. Ak. Amst., T. XIX) that the black dot on the base 

 of the caudal fin , and the black transverse streaks on the
