REPORT ON THE POLYZOA. 163 



not expect to get all the common forms even, as the result 

 of one season's labour, we may hope for additions to our 

 lists as the results of further search. 



I have followed mainly the classification of Mr. Hincks, 

 as laid down in the British Marine Polyzoa, with a few 

 alterations rendered necessary by the researches of Prof. 

 Lankester.* 



In conclusion, I must express my gratitude to the Eev. 

 Thos. Hincks, B.A., F.R.S., whose valuable help in deter- 

 mining species, about which I was in doubt, has always been 

 very willingly given ; to Mr. Quelch, B.Sc, of the Natural 

 History Museum, South Kensington, for kindly placing the 

 National Collection at my disposal for reference, and also for 

 kindly advice and help in naming the specimens ; and to 

 Professor Herdman, D.Sc, whose valuable assistance, amid 

 pressing avocations, has always been most readily accorded 

 me.
