CHIIYIOA PHANTASMA. •'• and S. (PI I, Fig. 8). 



This species is general in its distribution throughout the 

 moderately deep water of the eastern coast of Japan, from the 

 Hokkaido to Kyushu. In the neighbourhood of Misaki, Sagami, 

 where I have had an opportunity of examining living specimens, I 

 rind that it is taken in water of from f)0 to 300 fathoms. Its distri- 

 bution, however, like that of the Californian species, G. colliei, is 

 peculiarly local. The fishermen will sometimes fish for days without 

 obtaining specimens, and on the other hand on practically the same 

 ground, they will sometimes obtain them to the number of twenty or 

 more in a day. There are certain well-known portions of the reef 

 •• Outside Okinosé " where many specimens can usually he obtained. 

 This species corresponds in point of size with G. monstrosa Linn. 

 Female specimens measure 100 cm., or even more, in length ; males 

 are somewhat smaller, rarely exceeding 85 cm. 



Hi ihits. 



The tisli are usually sluggish in their movements when kept in 

 shallow water. They swim about slowly, but oftener remain in the 

 same position, merely balancing, moving their pectorals up and down, 

 in slow rhythm. Tn confinement — e.g., in shallow water, in large 

 floating fish baskets — they rarely live longer than the second day. 

 At their accustomed depth, on the other hand, judging from their 

 behavior when freshly caught. I am convinced that these fish are 

 normally very active, far stronger and more alert than I had been led 

 to believe : for one is inclined to assume from their highly specialized 

 dentition and poorly developed caudal tin that their movements are 

 sluggish, similar to those of lophobranchs or teradonts.
