The names of head bones of Cyprinus and Carassius, which are recorded in the books written in Japanese, are in great confusion. That is, the bones described and figured as the ethmoid, vomer, palatine, nasal, and basisphenoid by S. GOTO and others are disgnated successively and respectively as the vomer, palatine, ethmoid and sphenotic by I. ARIMOTO. But as the results of my comparative studies on the skeletons of the various teleostean fishes and other vertebrate animals, it was proved that the structure of the skull of Cyprinus or Carassius is essentially similar to that of the other common teleostean fishes; and that the bones called in the names of the nasal, ethmoid, vomer, sphenotic, prefrontal, and Palatine are arranged in nearly the same manner as those of the latter fishes as be ssen in ARIMOTO'S book. Therefore, I think that definition of the bones by I. ARIMOTO must be regarded to be quite right, while those by S. GOTO and others should be erased.
