Skin very rough ; densely covered with prickles, each of 

 which has a long central cusp and a pair of short lateral cusps. 

 Scales on the upper edge of tail behind second dorsal scarcely 

 enlarged, not differentiated. 



Color in formalin brownish or grayish, with some irregularly 

 scattered, whitish, round spots, the diameter of each spot being 

 about one-sixth or one-fifth diameter of eye ; dark brown blotches 

 with similar spots, somewhat cross-band-like and forming large- 

 meshed reticulum by joining with one another. All the fins, 

 except anal, are colored and marked in a way similar to above ; 

 the anal dusky or brownish, with very distinct markings. Under- 

 surface pale. 



The species differs remarkably from Catulus burgeri (Müller 

 & Henle) in having pale round spots instead of black ones. 



The species is very common near Misaki, where it is known 

 under the name *' Torazame " or *' Tiger shark" on account of 

 its marking. 



The type, a male 35.5 cm. long to caudal base, was taken at 

 Misaki, Sagami, on March 13"', 1904. It is presrved in the 

 museum of the Zoological Institute, Science College (Mus. No.
