OF MADEIEA AND NEIGHBOUEING ISLANDS. 277 



Busk's and o£ Hincks's species, and also for very kindly consiiltino- for me 

 two works Avhich were not in my own library. 



Dr. S. F. Harmer, who has made a special study of Talmlipora, has kindly 

 examined for me the two or three specimens I had belonging to that some- 

 what difficult genus, the species of which have been so greatly confused. 



The total number of species of Polyzoa contained in this catalogue is 139. 

 Of these Professor Busk had included 45 species in his papers of 1858-1861 

 Mr. Hincks enumerated 24, of which 21 were additions to the fauna. 

 Mr. Waters named 52, of which 28 had not previously been recorded ; and 

 Mr. Johnson described 7, of which 6 were not previously known. This 

 paper contains 39 species new to Madeira, making up the total number 

 previousl}^ mentioned — 139, of which 114 arc recorded on my own authority. 



In the catalogue of species which follows, the capitals B., H., W., or J., 

 after the name of the Polyzoon indicate that it has previously been recorded 

 from Madeira by Busk, Hincks, Waters, or Johnson, as the case may be.
