Part III. Eighth Annual Report 
Last appearance. — 16th October, very few. 
Most plentiful. — In June, a few generally each time — mature forms, S 
and 9 . Parasitic Udonella caligorum once or twice seen. 
This form was not very frequently procured this year. It is sometimes 
abundant in the free condition in November and December. 
Only once in Bottom-Tow-Net on 5th July, — 1 specimen. 
Surface-Totd-Net. 
On July 18th, very few. 
These move on the surface of the living cod with great activity. 
In their stationary larval form (Chalimi) they are very frequent on the 
young food-fishes, such as cod, whiting, green cod, and Pleuronectids. 
LARVAL ANNELIDS. 
Neuine — group. 
Bottom-Tow-Net 
The larval forms of Nerine and Pdlpdom made their appearance in this 
net about the 4th July, though some years they are found much earlier, 
and they continued in considerable though diminishing numbers till the end 
of October. A few occurred subsequently till December. They were 
most frequent in September, though also in large numbers in July and 
August. 
Surface-Net. 
The Nerine (/roup) were first observed on the 30th July, and they con- 
tinued till the 8th October. They were most frequent in September, 
when some occurred daily. In July a few were captured two or three 
times ; while in August similar numbers appeared about six times. 
The most common larval form was Polydora, so abundant along the 
rocky border and in dead and living shells everywhere in and near the 
Bay. The adult bores into various rocks and shells and is thus stationary, 
but the swarms of larvae spread the species throughout the ocean. 
Polynoe — group. 
Bottom-Net. 
These were first noticed on the 18th July, and they continued till the 
17th October or a little later. They were most frequent in July, when 
they were sometimes (e.g., 25th) in swarms. They were captured often 
in September and occasionally in August. 
Surface- Net. 
They were only procured once or twice in September. 
Many of the Polynoidae are ripe in January, and their larva? abound in 
rock-pools and tow-nets a little later. 
Terebella — group. 
Bottom-Net. 
The tubes containing the larval Terebellye appeared at the beginning of 
July, and a few continued till September, though they were most frequent 
in July. 
Surface-Net. 
A few occurred only on the 26th July, so that they are comparatively 
rare in this region of the water.
