PELAGIC LIFE, FALMOUTH. 313 



Auffust. During this month the surface temperature of the 

 sea varied but little. On the 6th, surface temperature heing 

 6r9°r, Pilidium and Auricularia larvse were very abundant in 

 the tow-net. In the same gathering I secured a single specimen 

 of what I imagine to be an advanced larval form of a species of 

 Holothurian. I made two drawings, and later cut some serial 

 sections of this specimen, but in spite of all my efforts I was 

 unable to identify the animal. On the 8th, the wind blowing 

 fresh from the south-south-east, surface temperature 61^ F, and 

 tide three-quarters ebb, two specimens of Muggioea atlantica 

 were found for the first time this year in the tow-net gathering. 

 I also noticed that Oithonia spinifrons was very abundant. 

 During this time some very large specimens of Chrysaora 

 mediterranea were seen just under the surface of the sea in 

 various parts of the harbour, and also in the bay. I have 

 several years ago seen this species very abundant in the sea near 

 Newquay. On the 11th the surface temperature was 60-9° F. 

 A single specimen of Corycseus anglicus and one very early 

 stage of Actinotrocha were the only interesting forms captured 

 on that day. During the rising tide on the 15th, the wind 

 being fresh from the south-west, and surface temperature 61-3° 

 F, a very rich gathering was made with the tow-net. Muggioea 

 atlantica occurred in profusion, and continued very plentiful in 

 surface-net gatherings for some time later. During this time 

 cypris stage of Balanus, Lizzia octopunctata, Sarsia tubulosa, 

 and S. prolifera were very abundant in the tow-net. The latter 

 portion of this month was very wild and quantities of rain fell. 



September. On the 1st, the wind being from the south- 

 west and blowing fresh, a considerable fall in the surface 

 temperature was noticed, 57"3° F being surface temperature on 

 that morning. On this occasion Corycseus anglicus occurred in 

 abundance ; a single female of the same species with ova 

 attached being noticed. In the same gathering large numbers 

 of Sarsia gemmifera occurred. On the 5th the wind was light 

 and variable, surface temperature being 57° F. In the gathering 

 made on this morning, only one specimen of Corycaeus anglicus 

 was seen. I also noticed in that gathering a few specimens of 

 a species of Lizzia which I have been unable so far to identify.
