FISHES COLLECTED IN JAPAN. 267 



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, Benard, Buysch, Valentyn, &c. There appear 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 in the Faun. Jap. It seems to belong to the variety called acumi- 

 natus, by Linnseus. 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. 



Bichardson founded this genus on a fish from Van Diemen's Land, and describes it as 

 Oplegnathus Conivayi in the Proceedings of the Zool. Soc, 1840, p. 27, and in full detail as the 

 Hoplegnathus G'onwayi in the Transactions of the same society, vol. Ill, p. 145, pi. 7. In the 

 Beport 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,
