260 NOTES ON THE FAUNA OF FAliMOTTTH. 



the tow-net, after working it for twenty minutes, into a jar, the 

 water was quite turbid owing to their presence. 



A. few days later the exceptionally strong autumnal spring 

 tides began, and most of the days were spent shore hunting. 



November. The weather was unsettled and cold during most 

 of this month. On the 6th, the surface temperature was 54°F.; 

 10th, 55°F.; 13th, 55-3 F.; and 22nd, 526 F. 



Only two surface-net gatherings were made during this 

 month, and both shewed a considerable decrease, both in 

 quantity and variety in surface life. 



On the 6th, a few Sagitta bipunctata and Olausia elongata 

 were the only forms observed in the gathering made during that 

 morning. On the 22nd, the common copepod Olaiisia elongata 

 occurred in considerable quantities, but no other forms were 

 detected. This was the last gathering made during this year. 

 Fauna Notes. 



Infusoria. While engaged in an attempt at rearing lobsters 

 in captivity during the summer months, I found attached to the 

 "berries" of those females which were procured from depths 

 ranging from 20-35 fathoms some exceptionally fine colonies of 

 Zoothamnium arbuscula. 



Medusce. It was not till the 1 6th of March that an example 

 of Ehizostoma pulmo was seen in this neighbourhood. From 

 that day till the fall of the year only an occasional specimen 

 was seen ; a striking contrast to my last year's experiences. 



Some remarkably fine specimens of Bolina hydatina were 

 dipped from the sea with a cup during high water near the 

 extremity of the eastern breakwater at the end of May. Aurelia 

 aurita abounded in the sea during the whole summer. The 

 planuloe were given off during the early part of August. 



Actinaria. Halcampa chrysanthellum is to be dredged in 

 fair numbers not very far to the westward of Lugo buoy. 



EcHiNODERMATA. When I first commenced dredging in 

 Falmouth Harbour, the beautiful feather star, Autedon rosaceus, 

 was one of the commonest forms to be met with in the deep 

 water. Since then they have steadily decreased in numbers, and 

 one can scarcely now obtain a single specimen where in previous 

 years they were so numerous. Their place seems to have been
