150 CATALOGUE OF ADDITIONS TO, AND ALTERATIONS 



present time. I make no pretence to scientific training, being 

 only a practical naturalist. I may mention that Hinck's 

 Catalogue was drawn from " South Devon and South Cornwall," 

 the present one from Cornwall onhj, and we have not such chances 

 as Mr. Hincks had of gaining rich stores from the Brixham, &c., 

 trawlers ; under these circumstances it ought not to be expected 

 that the Cornish list can be such a long and valuable one, 

 especially in deep water forms ; however, we have not been 

 altogether idle, and I hope we shall not be accused 



" Of dropping buckets into empty wells, 



And growing old in drawing nothing up." 



It has been to me a difficult task, and should I live a little 

 longer, with the new life put into natural history research of 

 the large army of young, well-educated collectors, very many 

 more species and genera of our loved ones will be added to 

 our lists, and further additions or new lists must be again 

 made out. The number of species noted in my present list is, 

 viz. — 



Hydrozoa 29 



Actriuzod 29 



Polyzoa 95 



Madreporia 4 



— 157 

 Of these, 90 are additions to, and 



alterations in Couch's list .... 90 



Leaving in the old list 67. 



On examination of the list it will be seen that some of the 

 additions are extremely rare, and two of them at present have 

 been found in Cornwall only, one of these being unique. These 

 rare ones have also been found in Pliocene strata, thus showing 

 a great range in time. 



In addition to the number of species in the foregoing table, 

 fifteen species of " Naked-Eyed Medusa " of Porbes have been 

 found on the Cornish coast ; these I have not inserted in it, from 

 not being able to give their right parentage, and have thus used 

 only the names given to them by Porbes (see page 157 of this 

 paper) in his Monograph, published by the Eay Society in 1848.
