316 PELAGIC LIFE, FALMOUTH. 



this Siplionophore were secured. Since that date this interesting 

 species has disappeared from surface-net gatherings. It is 

 worthy of note that Muggioea atlantica has always been present 

 in greater or less abundance in surface-net gatherings from 

 August 8th to November 26th in the sea near Falmouth. I 

 may here also direct attention to the fact that Evadne and Podon 

 also vanished from surface-net gatherings after the 23rd of that 

 month. On the 30th the surface temperature of the sea was 

 52" F. 



December. Gales of wind from various quarters prevented 

 my getting afloat till the 6th of this month. On that day the 

 surface temperature of the sea was 50° F. In my surface-net 

 gathering I found Coryceeus anglicus fairly abundant, six 

 females of that species having ova attached. In the same 

 gathering a few small specimens of Oithonia spinifrons were 

 noticed, and also six small Sagitta. On the 10th the surface 

 temperature was 49° F, and the tide high- water when the net

 in abundance. In the same gathering were large numbers of 

 Corycaeus anglicus with quantities of a species of diatom 

 attached to various parts of the cuticle. At this time I also 

 noticed numerous specimens of Clausia elongata covered with 

 diatoms. 



On the 16th of this month, last year, I captured while 

 working my tow-net in the harbour a single specimen of 

 Nyctiphanes couchii. Since that date up to the present time 

 I have not captured another of that species. 



On the 14th of the current month it was high water at 

 noon, the wind having been blowing steadily from the westward 

 for some days previously. On that morning I made a surface- 

 net trip, and worked my net across the tide about two miles 

 south-east of the Manacle rocks. The surface temperature at 

 this point at 12-. 50 being 51-9° F. On making a hurried 

 examination in the boat of the contents of the tow-net, I was 

 pleased to observe several specimens of Nyctiphanes couchii. 

 The wind had been steadily increasing in force ever since I had 

 left Falmouth, and when the first gathering had been made the 

 tide had begun to ebb. As a natural consequence there was a
