In the same paper (Müller 1847: 358) we find detailed information on the type locality [translated]:
“On August 26 [1836] when we stayed at the Kampong Kwâla-pattai, [east longitude 115, Lat. 2 S.]
we made excursions in the surroundings when we visited a small lake, Dano Mahoeroeng, which is
situated about half an hour upwards from the river Doeson, not far distant from its left bank and connected
to the large river mentioned above by a narrow canal. There we encountered two fishermen who by means
of common local cast nets (djala) had caught many Osphronemidae (mainly Helostoma Temminckii and
Ophiocephalus planiceps), a few cyprinids and several specimens of the beautiful new fish that we have
described and depicted under the name Osteoglossum formosum.”
