C. bankanensis, drawing of Bleeker's atlas, table 397, fig. 1Bleeker's drawing of C. bankanensis, taken from his famous ichthyological atlas. If you have it in your channa shelf (several hundred thousands Euros ;-) go for table 397, fig. 1, else thank God, there is an Internet to save this ichthyological memory.

Head of c. bankanensis, drawing of Bleeker's atlas, table 397, fig. 1aBleeker's drawing of the head shields of c. bankanensis, taken from his famous ichthyological atlas. Drawings of head shields were meant for species identification. Bloch 1793 started with this method and this method is still used.

Aanm.Deze Ophicephalus schijnt na verwant te zijn aan Ophicephalus serpentinus CV. an Siam, van welke soort in de groote Histoire naturelle des Poissons slechts eene beschrijving der kleuren van het ligchaam voorkomt, benevens eene opgave van de getallen der vinstralen. Die kleuren zijn evenwel eenigzins anders dan bij mijn specimen en de getallen der vinstralen verschillen aanmerkelijk t. w. D. 44 A. 26. Ophicephalus bankanensis is ook verwant aan Ophicephalus rhodotaenia Blkr. (Nat. Tijdschr. N. Ind. II. p. 425) 1 van Borneo, doch deze heeft eenigzins andere kleuren, slechts 25 aarsvinstralen, den kop slechts 1 1/2 maal zoo lang als hoog, 50 shibben op ene overlangsche rei enz.
