210 PELAGIC LIFE, EALMOUTH. 



neighbourhood of Land's End, to make a series of surface 

 nettings, and report on the captures obtained. Another observer, 

 stationed at St. Ives, Newquay, or Padstow, would also render 

 great service by observing the various forms of life on the North 

 coast. I simply mention this with the hope that some member 

 of this Society may be induced to devote some attention to this 

 interesting study : for I am convinced that our fisheries will be 

 greatly benefitted by the results so obtained. 



On the following afternoon I was about a mile south of the 

 Black -Eock in my canoe, and about 5 p.m. the wind fell light, 

 and in half an hour there was a complete calm. As I happened 

 to lean over the side of the boat I soon saw some Tunicates 

 being swept past me by the rising tide, and in about half an hour 

 I found myself surrounded by innumerable quantities of these 

 animals. As the sun was shining brightly at the time these 

 specimens of Salpse presented a charming sight, the iridescent 

 chains sparkling in the sunshine. 



To enable one to form an idea of the numbers present, I 

 dipped a quart collecting-bottle into the sea, and on counting the 

 number of animals secured I found seventy-five specimens 

 present By the 5th, the surface temperature had risen to 62* F. 

 On the 8th, the temperature remained unaltered. In this 

 gathering only a few Tunicates were observed. The wind being 

 from the North had swept most of the pelagic forms to sea again. 

 On the 9th, three young specimens of Amphioxus lanceolatus 

 were secured in the tow-net, the largest specimen measuring 5 

 m.m. in length. On the 15th, I worked the surface-net at 4 a.m. a 

 mile south of the Black-rock, there being a calm at that time 

 and the tide on the flood. I found in this gathering that Corycseus 

 anglicus with ova attached, Muggioea atlantica, and Cyphonautes, 

 were all abundant. Amongst the rarer forms may be mentioned 

 six Willsia stellata, and four Sarsia gemmifera, and several 

 Monstrilla rigida. On the 27th, I managed to make a short 

 surface-netting trip in the afternoon, surface temperature, at 

 3.30 p.m., being 59-6° P. In this gathering large numbers of 

 Muggioea atlantica were again noticed, and a few individuals of 

 Podon intermedius detected.
