PELAGIC LIFE, FALMOUTH. 45 



individual was in an immature condition. Being unable to 

 identify this specimen by any of the books in my possession, I 

 wrote to my friend Mr. Garstang, who kindly replied as follows : 

 " Your specimen is either a young Pelagia perla Slabber, or the 

 Pelagia stage of our common Chrysaora, probably the latter. 

 Our specimen is exactly like your drawing and is without any 

 trace of gonads." Be this as it may, the medusa in this stage is 

 rare, for we have only each secured a single specimen up to the 

 present time. I may, in conclusion, mention that my specimen 

 measures 14-m.m. in diameter. 



By the 21st, the Gelatinous algae had almost vanished, and 

 so tow-netting could again be resumed. 



Owing to the continuance of northerly winds surface-netting 

 was abandoned, and the tow-net was worked three feet from the 

 bottom in the main channel in the harbour with some success. 

 In the gathering made that morning, Podon intermedins and 

 Evadue nordmanii occurred in profusion. Attached to the 

 umbrella of a species of Leptomedusa was a parasitic larval 

 actinian, which serial sections clearly shewed to be identical 

 with that figured and described by Prof. Haddon.'^' This specimen 

 measured 3-m.m. in length. From that day till the 18th of the 

 following month I secured on different occasions about twenty 

 additional specimens, and in addition to examining the structure 

 of some, by means of serial and optical sections, I made attempts 

 to raise a few to the adult condition. These efforts were, 

 however, unsuccessful, — for, being unable to obtain any 

 Leptomedusse after the end of June, I tried to feed them with 

 raw meat, but could not induce the actinians to eat it, and so the 

 specimens miserably perished without undergoing any material 

 changes whilst I had them in my possession. 



June. During the early part of the month, examples of 

 Bolina hydatina occurred in abundance in the harbour ; some of 

 the specimens measuring upwards of 5-4 cm. in length. On the 

 4th the only form of interest collected by the surface-net was a 

 single Tira octona, Plemming. On the 7th a single Bouganvillia 

 Britannica was noticed in the surface-net gathering made that 

 morning. A dead specimen of the same species of Eadiolarian 

 — A- Elastica — which occurred in such profusion in this district
