1915] ON CLUPEA PALLASII CUVIER AND VALENCIENNES 103 
The spawning areas agree very well with the areas in which the 
herring appear in numbers earlier in the season. It would seem that one 
race spawned in Kulleet Bay (Chemainus Bay) from Yellow Point 
South. One should infer that another race spawned at Cowichan Gap, 
but we have no record of this. Another race spawned from Breakwater 
Island, through Gabriola Pass to Pylades Channel, one to the north 
and east of Gabriola Island and one from Qualicum to Nanoose Bay 
and a little farther eastward. All of these places were fished extensively 
with the exception of the north and east of Gabriola Island, where the 
eastern and southeastern storms of the winter season make fishing a 
troublesome occupation. Apart from these localities, extensive fishing 
was done in Northumberland Channel along the shore southeast from 
Jack Point. This race was fished until March 2, when large hauls were 
made in the channel just off the entrance to Dodds Narrows. These 
fish apparently passed through Dodds Narrows, as they appeared in 
large numbers on the Mudge Island shore and in the neighborhood of 
Round Island on March 5, but there was no sign of spawning here. 
They must have gone on the southward, but we have no record as to 
where they spawned, although spawning must have taken place soon 
afterwards, since, as has been previously noted, some of them were 
spawning in the seine on March 2. 
After spawning the herring pass out into deeper water, probably 
not so very far away, as they make occasional visits into shallow water 
during the remainder of the year. How common these visits are it is 
impossible to say, as there has been little observation made in that 
regard. Evidently there are inducements for such migrations other 
than the necessity of finding suitable spawning grounds. It would be 
useless to present any conclusions concerning migration, however, until 
these conclusions are backed by a greater amount of evidence. It 
might be noted, though, that the herring have not the same trouble to 
get into deep water here as they have in the North Sea, since a depth 
of 150 fathoms or even 200 may be reached in the Strait without going 
far from the shore. 
EMBRYOLOGY AND LARVAL DEVELOPMENT 
In the mature herring just before spawning the milt and roe make 
up a very noticeable proportion of the whole weight. The largest 
male gonad examined weighed 22.7 grams, and as the fish weighed 
158 grams, the two gonads made up over 28 per cent. of the weight; the 
largest female gonad weighed 18.6 grams, the fish 151.5 grams, 24 per 
cent. of the total weight. Although the younger and smaller fish do
