[Plates V. & VI.] 



In 1861-62, I published, in the pages of the '■ Annals,' a 

 ^' Catalogue of the Zoophytes of South Devon and South 

 Cornwall," including under the term "zoophyte" the Hydroida, 

 the Lucernarian section of the Discophora, the Actinozoa, and 

 the Polyzoa — in short, the groups embraced in Dr. Johnston's 

 ' History.' As many as 241 species* were recorded as occur- 

 ring in the district, of which 18 were new to science and 3 

 found a place for the first time in the fauna of Great Britain. 

 Others have been met with since, including two or three very 

 interesting new forms of Hydroida, which I have lately pro- 

 cui-ed by dredging, in Salcombe Bay ; and in the present 

 Supplement 24 species are added to the list, raising the whole 

 number of south-western forms hitherto observed to 265. 



A few species which had only been found in the north have 

 their range of distribution extended southward. Syncoryne 

 eximia^ which I have noted, in my ' History of the British 

 Hydroid Zoophytes,' as confined to the north-eastern coast, 

 where it is the common representative of its family, has just 

 occurred to me in great abundance in South Devon. Calycella 

 fastigiata (Alder) and Halecium sessile (Norman) are added to 

 the group of forms which is common to the western side of 

 Scotland and the south-west of England. Diastopora sar- 

 niensis (Norman), found hitherto only in the Channellslands, 

 proves to be also a native of the Cornish coast. 



The new species of Hydroida which I am about to describe 

 are peculiarly interesting. One of them must be referred to a 



* I omit Tubularia Dumortierii, which was inserted in the Catalogue 

 by mistake.
