'The name Tai (written dai in compound words) in Japan is applied to Pagrus 

 major primarily, a most valuable and characteristic Japanese fish, sacred to the fish 

 god Ebisu. The particle enters into the name of most perch-like fishes and cor- 

 responds to our word perch or more exactly to porgy (Pargo, Pagrus, ndypoi). 

 Uwo in Japanese means fish. 



^According to Waite, the date of the fascicle of Fauna Japonica containing the 

 account of Scarodon was published in 1844.
