204 NOTES ON THE FAUNA OF FAiMOUTH. 



The presence of several specimens of Coryceeus anglicus with, 

 ova attached, and one specimen of Saphinia mirahiUs is note- 

 worthy. After a long interval, a single specimen of Calagus 

 rapax was found in the gathering of the 17th. 



Specimens of Podon, carrying a single winter egg, were 

 fairly common during this time. 



Novemher. The surface temperature of the sea during the 

 first week remained unchanged at 56°F. Between the 8th and 

 15th it fell to 53-3°P., and during the next eight days a further 

 steady reduction took place to 52-9T. On the 24th there was a 

 slight rise to 53 "ST., and during the remaining portion of the 

 month the variation was very slight. The last half of this month 

 was characterized hy an unbroken calm, a most unusual event for 

 the time of year. 



There was an appreciable diminution in the quantity of 

 the plankton during this month, although at the commencement 

 it was far above the average, specimens of Muggisea and Cory- 

 caeus anglicus being exceptionally numerous. A single worm 

 larva, which I believe to be a young Aphrodita, was captured 

 tured on the 13th. The presence of a single Beroe in the 

 tow-net on the 30th is interesting. 



December. The surface temperature of the sea remained at 

 53"3°r. during the first week; this was followed by a rapid fall 

 to 48°F., at which point it remained practically unchanged till 

 ^he close of the year. 



CcELENTEEATA. During the spring and summer of both years 

 Aurelia aurita has been practically absent from this district. 

 The presence of a single ephyra stage of Aurelia in the tow-net 

 on the 17th January, 1898, led me to expect that a greater num- 

 ber would follow, but in spite of many excursions to various 

 places in the harbour and also up Truro river as far as Malpas, 

 during the summer of 1898, only one battered adult specimen was 

 seen. This was observed in the docks on the 27th April, and 

 was found to measure 30 m.m. in diameter. During 1899 not a 

 single Aurelia aurita was ^seen. The last time this species was 

 abundant in this district, was in the spring and summer of 1895.
