not materially increasing their length in relation to the size of the 

 body. Small examples resemble species of Podothecus, perhaps 

 looking most like P. xystes. 



Podothecus toJcuhire described by Doctor Ishikawa * is probably 

 based on an injured example of D. sachi from Hokkaido, where dried 

 specimens may occasionally be seen in the small shops.

PODOTHECUS THOMPSONI Jordan and Gilbert. 



A single specimen from Mororan 90 millimeters long appears to 

 belong to this species. When compared with cotypes from Iturup 

 Island (60 miUimeters long), the snout appears a little longer, the eye 

 is shghtly smaller, and the spines of the head and the ridges of the 

 opercular region are somewhat higher and more spine-like. The 

 dorsal has 9 spines, 6 rays, and the anal 6 rays.

CYCLOPTERICHTHYS VENTRICOSUS (Pallas). 



One specimen 330 millimeters long secured at ^lisaki. The species 

 has not heretofore been reported south of Aomori. The Misaki 

 specimen was obtained from Air. Aoki and the date of its capture is 

 unkno^vn. This example was a female in which the oviducts were 

 filled with eggs. By carefully weigliing and counting, it was estimated 

 that there were in aU 44,619. 



Individuals of this species may be found in pools, under rocks or 

 attached to their sides. They swim very slowly and are perfectly 

 helpless when removed from the water, inflating the body with air
