Oshima: Fishes of the Family Mugilid.^, 245 



Market on Jan. 22, 1921, preserved in the Museum of the Institute of 

 Science, Formosa. C. M. Cat. of Fishes, No. 8279, Toko, Dec. 23, 

 1920. 360 mm. Coll. M. Oshima. 



Habitat: This is one of the most abundant mullets occurring- in the 

 waters of Formosa. Our specimens came from Inzampo, Ritakukan, 

 Toi, and Tamusui of the State of Taihoku ; Kwaren River at Kada, 

 and Botansha, Kwarenko ; and from Anpin, Takao, and Toko. 



Remarks: The present species is so closely allied to Mtigil a:ur 

 Forskal of the Indian Ocean that it has been referred to the latter by 

 several authors. It is distinct/ however, from M. (vur in having 

 mandibular bones which meet at an obtuse angle, and thirty-eight or 

 thirty-nine scales in a lateral series instead of forty-two to forty-four 

 (according to the description by Francis Day). Moreover, the depth 

 of this species is much less than that of Mugil ocur, measuring more 

 than six times in the total length. 



Another relative of the present species is Mugil cephalus of the 

 Mediterranean. It differs from the common Formosan mullet in hav- 

 ing a deeper body and more than forty scales in a lateral series. 



We refer this species to Mugil japoniciis Temminck & Schlegel 

 from Nagasaki, separating the latter from the common Japanese 

 mullet regarded as identical with Mugil cephalus Linnaeus. 



This species is very common on the western coast of Formosa. 

 The season for capturing these fishes commences about the middle of 

 November, when they swarm close ashore along the coast of Shin- 

 chiku, coming from the western part of the Formosan channel, prob- 

 ably from Fokien, China. At first they migrate to the south along 

 the western coast of the island and return to the north, after deposit- 

 ing their ova somewhere in the high sea near" the southernmost cape. 

 They continue very numerous until about the end of February, 



The roes are salted and dried to prepare a special caviar, known as 

 " Karasumi " by the Japanese people.
