A CATALOGUE OF ADDITIONS TO, AND ALTERATIONS IN 

 THAT OF THE ZOOPHYTES OF CORNWALL, BY THE LATE 

 R. Q. COUCH, Esq; 



(fithlished in Part III, 1844, of the Transactio7is of the Royal Institution of Co}-nwalL) 

 By C. W. peach, A.L.S. 



In compliance with, the request of the committee of your 

 Society, I have endeavoured to make the additions and altera- 

 tions required to briug my late valued friend's work into 

 harmony with the Zoophyte lore of the present day. Great 

 discoveries of Grenera and Species have been made by the host of 

 collectors since it was published in 1844, and beautiful illustrated 

 works have been published. First, by the late Dr. Johnston, in 

 two volumes, which are still valuable for reference. Professor 

 Busk's admirable description of the Polyzoa in the British 

 Museum farther advanced our knowledge of the Polyzoa. To 

 the Rev. T. Hincks we are indebted for a book of two volumes 

 "On the British Hydroid Zoophytes," and in the present year 

 two more volumes by the same author on '' British Marine 

 Polyzoa," splendidly illustrated, have been published by Van 

 Yoorst. It is needless to say that they are well got up, and have 

 brought us up to the true state of the knowledge of both king- 

 doms of Hydroids and Polyzoa. Many other very useful books 

 and papers have been written also. I must, however, rest 

 contented with noting one more work, Grosse's '' History of 

 British Sea- Anemones and Corals," with coloured figures of all 

 the species known in 1860. Of this work it is sufficient to say 

 it is a most useful and valuable one. I must, however, mention 

 that Mr. Hincks published in the "Magazine of Natural History," 

 1861-1862, " A Catalogue of the Zoophytes of South Devon and 

 South Cornwall." In these works each author has made great 

 bhanges in the names and classification, the greatest, however 

 especially in the Polyzoa, published by Mr. Hincks in March last. 

 Prom all sources in my possession, commencing with Ellis's 

 " History of the Corallines," published 1755, 1 have endeavoured 

 to bring the history of our Cornish Zoophytes, above- 

 mentioned, into harmony with our knowledge of them at the
