named by him "/>. pkta Blkr.", with the colour faded and 

 mostly in a bad state of preservation, contains specimens 

 belonging without question to IL pkta C. V. = B. trifasciata Blkr. 

 More numerous arc 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.

Rostro-dorsal profile from dorsal to nape straight, from there 

 to snout declivous in a straight line or with a slight convexity 

 or concavity. Chin conspicuously prominent. Height t^.'j — 4.7 

 according to size. Head 3.1 — 3.4 in length. Eye 3.4 — 4.5, its 

 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 19111 to 2ist lateral scale. The 4th to 6th may be strongly 

 produced; the 5th 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 

 length of head. Height of caudal peduncle at base of caudal
