266 NOTES ON THE FAUNA OF FALMOUTH. 



Microniscus firmly fixed to the right side. Another interesting 

 feature is the extreme difficulty, I may say the impossibility, of 

 finding any staining fluid which will colour these parasites in at 

 all a satisfactory manner. I have nine mounted specimens, and 

 all save one is hardly tinted at all ; the single exception being 

 stained with carminic acid. 



On the 26th, a single dead specimen of Doliolum was 

 secured. 



July. The surface temperature of the sea was exceptionally 

 high during this month, and was never found to be under 61''!F. 

 on the 1st, and varied from that to 62-6 F. on the 31st, but the 

 continuance of ojGf-shore winds effectually prevented any oceanic 

 forms from being carried into the bay and harbour. 



On the 8th, Centropages typicus and Temora longicornis 

 were fairly abundant in the bay, and with them were a fair 

 quantity of Oorycoeus anglicus and Clausia elongata. On the 

 14th, a few Evadne and Podon were detected ; and on the 20th, 

 Appendicularia and various plutei were abundant. On the 24th, 

 a fresh breeze from the south, and afterwards from the south- 

 west, considerably increased the quantity and variety of the 

 plankton in the bay. Oyphonautes, Evadne, Podon, Oorycoeus 

 anglicus, Plutei, and Temora longicornis were all fairly abundant. 

 A single specimen of Ceratium tripos, and three Acanthometra 

 elastica, unfortunately dead, were also observed. 



August. The surface temperature of the sea during this 

 month was far higher than any previous year, and varied from 

 64°F. on the 3rd to 63°F. on the 13th. After that date there was 

 a steady fall in the temperature ; 62''F. being recorded on the 

 I5th, 62-6 F. on the 17th, 61°F. on the 26th, and from that date 

 to the end of the month the surface temperature of the sea 

 remained unchanged. 



On the 6th, an exceptionally prolific haul of Clytia Johnstonii 

 was made with the tow-net in eighteen fathoms of water near 

 West Narrows Buoy. On the 1 6th, favored with a light north 

 wind, I made a surface-net trip to the Dodman, and spent some 

 hours working my net at various depth about two miles from 

 that well-known headland. The surface temperature of the sea 

 being 6r3° F at 1 p.m. In bottom net the following forms were
