Type. — South African Museum. 



Distribution. — South Africa, from Zululand to Delagoa Bay ; Korean Strait, 

 Japan. 



Specimens Examined : 



1(198 mm.). Paratype. 22 miles N. of mouth of R. Tugela, Gilchrist. 



Natal, 63-73 fms. 



I (245 ., ). Natal. 



I (182 ,, ). Sea of Japan, off Nagato Prov. Tokyo Imp. Univ. 



The type of C. macrolepidotus, taken by the " Albatross " in the Korean Strait, 

 in 66 fathoms, is only 59 mm. in total length. The teeth were described as uniserial 

 in the upper jaw, with several large teeth irregularly placed, and uniserial posteriorly 

 in the lower jaw, becoming biserial further forward and forming a narrow band at the 

 symphysis. Col. Tenison has e.xamined the type in the United States National Museum 

 (No. 75670), and assures me that it is a young example of C. macrolepis. An adult 

 example from Japan received after the completion of this work confirms this view.'
