named by him "B. picta Blkr.", with the colour faded and 

 mostly in a bad state of preservation, contains specimens 

 belonging without question to B. picta C. V. = B. trifasciata Blkr. 

 More numerous are the specimens belonging to B. anabatoides 

 Blkr. A few of them show still the markings of the dorsal as 

 drawn in the otherwise rather bad figure in BLEEKER's Atl. 

 ichth. on which TATE REGAN founded B. Bleekeri. REGAN 

 in his valuable revision of the genus Betta not having had 

 the opportunity of seeing the original specimens of BLEEKER, 

 was misled by BLEEKER's figure and his very insufficient 

 description in his last paper (Verh. Akad. Amsterdam XIX. 

 1879, Poiss. pharyng. labyrinth, p. 26), in which he united 

 his former B. anabatoides and trifasciata under the name B. picta. 

 His diagnosis, taken from 2 different species, was of course 

 erroneous and misleading.

 or concavity. Chin conspicuously prominent. Height 3.7 4.7

 diameter about equal to snout, 1.7 to 2.6 in postorbital part 

 of head and 1.2 to twice in nearly flat interorbital space, which 

 goes 2.5 2.8 in length of head. Maxillary reaching frontborder 

 of eye or somewhat behind it. Origin of dorsal somewhat more 

 or less than one eye-diameter nearer to caudal than to head, 

 separated by 26 29 praedorsal scales from snout, opposite 

 to 19 th to 2ist lateral scale. The 4^1 to 6 th may be strongly 

 produced; the $*h reaching far on caudal. Anal with a basal 

 sheath of 2 3 usually regular rows of small scales; the hin- 

 dermost anal rays before the two last may be strongly produced 

 and reaching far on caudal. Caudal large, spoon-shaped, its 

 2 central rays more or less produced. Pectorals 1.3 1.4 in
