312 PELAGIC LIFE, FALMOUTH. 



in the harbour but also in the open sea. Owing to the fragile 

 nature of this species, it is difficult to collect perfect specimens 

 in the harbour. On several occasions I was able during this 

 time to capture perfect specimens of this species about three 

 miles south of the Zoze point. On the 27th, a few Auricularia 

 larvae were obtained. On the 30th the surface temperature was 

 56-3°F. On that day, specimens of Appendicularia were 

 exceedingly abundant in the tow-net. 



July. On the 4th the surface temperature was 56-3° F. 

 During this month Appendicularia continued to be very 

 abundant in my tow-net gatherings. On the 7th, the following 

 species of naked-eyed medusse were to be found in large 

 quantities : Sarsa tubulosa and Thaumentias hemispherica, both 

 recorded by Dr. Cocks ; Lizzia octopunctata, which at times was 

 swarming in the sea, appears to be new to the district. In the 

 same gathering occurred two specimens of Monstrilla rigidia, to 

 one of which ova were attached. On the 11th I took several 

 Lizzia blondina. In the same gathering a single specimen of 

 Campontia eruciformis was observed. On the 13th the surface 

 temperature was 59-9°F. On that day I got several specimens 

 of a species of medusa, quite new to me. I made some careful 

 drawings of one or two, and finally sent some of the sketches to 

 Mr. Garstang; but he was unable to identify the specimens. 

 Examples of this species continued to be fairly numerous in 

 surface-net gatherings from that date till the close of the month, 

 when they suddenly vanished. On the 1 6th several larvae of 

 Eucratea chelata were again secured. On the 21st a few Sagittse 

 were captured in the tow-net, the gonads of all the specimens 

 examined being empty. On the 28th we had easterly winds in 

 the morning, surface temperature being 60° F. The gathering 

 made with the surface-net across the rising tide on that morning 

 was very rich in results. Zosea and megalope stages of species of 

 Crustacea, Centropages typicus, males only, various species of 

 Plutei, Oithonia spinifrons, Evadne, Podon, Cyphonautes, and 

 various species of spinid larvae were all abundant. In this 

 gathering I observed a single specimen of Tornaria in a very 

 early stage of development. On the 30th, Pilidium began to 

 appear in tow-net gatherings, surface temperature on that day 

 being 61-9°F,
