bottom of the funnel having an inclination which becomes lower toward the 
shore, fixed with its edge into the sea bottom as in the case of the screen-net. 
Therefore the fish, even those moving near the sea bottom, being driven 
in this direction, run on the funnel and are entrapped in the bag-net. The 
Fukubc-miii has many forms, but it is only necessary to mention two in this 
paper. The first is made with a double opening, the bag-net has a mouth on 
both sides of the screen-net so that it entraps the school equally from both 
sides. This kind is used for fixing on the back of narrow banks with the 
deep sea at both sides. The second is made with only one opening, — the 
bag-net has a mouth on only one side of the screen-net, so that the school 
comes into it only from the mouth-bearing side. This is used for fixing on 
the slopes of these submarine valleys, which have a depth only at one side 
and a shallow vast floor on the other. 
The schools of Hotani-ika come into the net in the fishing season after 
sunset and never during the day, and the net drawn up at 9 or 10 p.m. is better 
filled than that drawn up at 3 or 4 a.m. This fact seems to suggest that the 
schools come near the coast from the deep in the offing when sunset ap- 
proaches, and as soon as they have laid the eggs towards evening go back in 
to the deep sea, and are entraj^ped in the net on their way back. They come 
very rarely to the surface of the sea even at night. 
There are 2 or 3 special submarine valleys of 100 or more fathoms, where 
various deep sea animals are caught, for example, Nigisu-scbikiba at Uozu 
(PI. Ill, fig. 5 ; p. 86, footnote) and Hirataebi-tegun-aiiiiba at Shimminato 
(ibid. fig. 2 ; p. 93). In those places, even in the daytime in the fishing season, 
Hotarii-ika are always gathered by a drag-net, though in other shallow parts, 
they are never caught. So it suggests that in such a depth even near the sea 
coast, they live also in daytime. And there are also several places where in 
the fishing season Hotai'u-ika are gathered by a hauling seine from land, after 
sunset, for example, Takatsuki at Namerikawa (ibid. fig. 4), Tai-jibiklba at 
Uozu (ibid, fig, 5) and Baichi at Kyoden (ibid. fig. 6), where there seem to be 
some suitable slopes for Hoiarii-ika to approach to the coast, having a vast
