314 PELAGIC LIFE, FALMOUTH. 



On the 10th the wind had changed to the north-west, and as a 

 natural consequence the surface-net gathering was not very rich 

 in species. A few specimens of Oithonia spinifrons and Sagitta 

 were the only forms whose presence called for any notice, surface 

 temperature on that morning being 56° F. On the 15th a 

 favorable opportunity occurred for a surface net trip seven miles 

 from land. Hitherto three or four miles from shore was the 

 greatest distance I deemed it priident to venture in my canoe. 

 During the two or three previous days the wind had been 

 blowing steadily from the south to south-west, and it seemed to 

 me most probable that if the surface-net were worked in 

 localities removed from shore currents, some interesting, and 

 perhaps new forms might be secured. My trip was a failure. 

 At the point most distant from land, specimens of Sagitta 

 occurred in abundance. On all the other occasions this form 

 was absent from the tow-net gatherings. All the other forms 

 captured were familiar to me, and in reality were not so varied 

 as those caught nearer the shore. Surface temperature was 

 57 "^ F. On the morning of the 19th the surface temperature 

 was 57'9°F. In my tow-net gathering made on that morning a 

 quantity of Tornaria and Pilidium were secured. In the same 

 gathering two specimens of Actinotrocha were noticed. Oithonia 

 spinifrons and Centropages typicus were also fairly numerous. 

 On the 22nd the wind was easterly and surface temperature 

 57-6°F. Evadne, Podon, Sagitta, and Auricularia were all 

 abundant in the tow-net gathering. About this time I secured 

 several specimens of the larval form of a species of Nemertine, 

 which I have been unable to identify so far. I have some of 

 these specimens preserved, and have also studied their internal 

 anatomy by means of serial sections. 



The interesting Siphonophore Muggicea atlantica continued 

 to be very abundant in surface-net gatherings during the month. 



October. On the 1st, surface temperature at 11.30 a.m. was 

 57-9'^F. The following forms were noticed in the gathering 

 made at that time: Sagitta, Evadne, Podon, Muggicea, females of 

 Corycseus anglicus with ova attached, and Calanus finmarchius. 

 A few small Monstrilla rigida were also detected. From that 

 date till the 8th the tides were very strong, and my attention
