“In the specimens of Osteoglossum formosum Müller & Schlegel (1844) from the lakes along the
Doeson river in South East Borneo the body depth fits 4 times in its length, its width fits 2½ times in its
length, its barbels are about as long as the snout, the dorsal fin has 18 rays of which only the first 3 are
undivided, and the caudal fin together with the caudal peduncle fits 5 times in the total length, whereas this
in my specimen fits only 4 ½ times in the TL. These differences, which partly might be explained by the
difference in age, do not give me the right to consider my specimen from the Sambas as a separate
species.”
