5-5 i 



Height 3.3 — 3.9, 4.3 to more than 5 in length with caudal; head 

 4^/3 — 575, nearly 6 — 7 in length with caudal. Eye 3 — 4I/.,, its 

 centre situated somewhat behind the middle of the length of the 

 head, i^j- — 2'/2 in interorbital space, in young specimens not, 

 in older ones much shorter than snout. Snout obtusely pointed, 

 projecting beyond the lower jaw, porous. Barbels four, very 

 small. Origin of dorsal in advance of that of ventrals, opposite 

 to loth or nth scale of lateral Hne, separated by 11 — 12 scales 

 from occiput. Dorsal deeply emarginate, anterior dorsal rays 

 more or less prolonged in adult examples. Origin of anal opposite 

 to 22°d or 2y^^ scale of lateral line. Anal more or less emar- 

 ginate, much lower than dorsal. Ventrals and pectorals sub- 

 equal, shorter than head. Ventrals opposite to I2tli scale of 

 lateral line and to third branched ray of dorsal. There are 

 three rows of scales between the lateral line and the root of 

 the ventral fin. Caudal deeply forked. Colour uniform, an indi- 

 cation of a faint lateral brown band in young specimens. Length 

 335 mm.

6. Tylognathus schwanefeldi (Blkr.). 



Lobocheilos Schwaiiefcldii Bleeker, Nat. Tijdschr. Ned. Inditi V. 1853, p. 523. 

 Lobocheilos {Lobocheilos) Schwanefeldi Bleeker, Ichth. Arch. Ind. Prodr. II. Cyprini, 



i860, p. 150. — Atl. Ichth. III. 1863, p. 57. 

 Tylognatlms schwanefeldi i Giinther, Cat. Brit. Mus. VII. 1868, p. 66. 



If this is really a distinct species, it differs, according to 

 Bleeker and Gunther, from T.falcifer by having the height 

 of the body equal to the length of the head. According to 

 Bleeker the height of the head goes i^/g — i^/^ in its length 

 in T. schwanefeldi, and 174 to scarcely more than once in 

 T. falcifer. Moreover T. sclnvanefeldi is said to have a light 

 yellowich narrow lateral band running above the lateral line. 



Specimens of both species of Bleeker's collection in our 

 possession, are in too bad state to controle the above statements.
