FISHES COLLECTED IN JAPAN. 15 
when no doubt remained on my mind that species of the same family of fish were thus proved 
to occur on the Asiatic coast of the Pacific also. Without an examination of a specimen, it 
would be difficult to place the Ditrema in the above families. It will probably be found to 
constitute a new genus under one of them, and no doubt other species will be discovered.

This fish has been figured by Vlaming, Renard, Ruysch, Valentyn, &c. There apnea to be 
several varieties of it, which may prove to be different species on actual comparison of speci- 
mens. The figure herewith given varies from the one in the Fauna Japonica, having the whole 
snout black, which is stated in the Hist. des Poissons to be sometimes the case. The second 
black band does not touch the opercle, and the third unites with the second under the spinous 
dorsal. According to the figure, the dorsal fin has 10.24 rays. The fourth and fifth dorsal 
spines are much shorter than inthe Faun. Jap. It seems to belong to the variety called acumi- 
natus, by Linneus. The name in the Faun, Jap. (Kohatatate) signifies small flag fish, or fish 
with a fin like a mast, that can be raised or lowered.

The drawing is so nearly like the figure in the Fauna Japonica that it seemed unnecessary to 
reproduce it. 
Richardson founded this genus on a fish from Van Diemen’s Land, and describes it as 
Oplegnathus Conway in the Proceedings of the Zool. Soc., 1840, p. 27, and in full detail as the 
Hoplegnathus Conwayi in the Transactions of the same society, vol. III, p. 145, pl. 7. In the 
Report of the fifteenth meeting of the British Association at Cambridge, in 1845, p. 247, he 
enumerates three species from China and Jupan, viz: the H. fasciatus and punctatus, of Schlegel,
