206 PELAGIC LIFE, FALMOUTH. 



following forms were noticed : Sagitta, Centropages typicus, and 

 Oithona Spinifrons were all fairly abundant; about six 

 specimens of Corycseus anglicus and one living Muggioea 

 atlantica were also observed. In addition to these forms I 

 noticed suspended in the water some highly refractive bodies 

 resembling in a marked degree minute fragments of mica. 

 Microscopical examination at once shewed that there were 

 present in the water immense quantities of a species of diatom 

 belonging to the genus Amphipleura. On the 9th, the total 

 weight of the inshore gathering was 0-3 grms, and the surface 

 temperature 47° F. On the i3th, the only form of interest 

 observed was that of some large Sagitta ; a specimen taken 

 at random measuring 14 m.m. in length. On the after- 

 noon of the 1 4th, I made a short tow-netting trip, after a 

 gale of wind from the S.W. I found in this gathering, in 

 addition to the usual forms, four specimens of a species of 

 Hadiolarian. Unfortunately they were all dead, but still they 

 were clearly recognizable. On the following day Mr. Bealey 

 made a gathering two miles south east of the Lighthouse, 

 surface temperature, at 1-30 p.m., being 49° F. I found in this 

 gathering two specimens of the interesting shrimp with luminous 

 organs Nyetiphanes Couchii, and one example of Muggioea 

 atlantica. It is curious to notice the absence of Kadiolarians in 

 this gathering, for I certainly expected to find some. On the 

 21st, the wind was from the W.N.W. and surface temperature 

 48° F. In this gathering one specimen of the ephyra stage of 

 Aurelia was detected for the first time ; the total weight of the 

 gathering being only 1 grm. The next day (22nd) Mr. 

 Bealey made a gathering with the surface net off Coverack 

 about noon, the surface temperature at that time being 49° F. 

 The captures made on this occasion were very numerous, the 

 following forms being observed. Several specimens of 

 Siphonophore Muggioea atlantica 3 m.m. in length ; Clausia 

 elongata, Dias longiremus, Centropages tj^picus, and Corycaeus 

 anglicus were all abundant. On the 25th, after fresh east winds 

 for the preceding two days, the net was worked across the rising 

 tide off the Black-Eock ; my reasons for working the net there, 

 were mainly due to the fact that I noticed numerous gulls in the 

 neighbourhood. Keeping the net down the usual period of
