Bird-Caves of the Bermudas. 629 



examined by me to prove this was so perfect and so 

 abundant, that it left not a scintilla of doubt on the subject. 

 There were also repres^ented two new Shearwaters, both 

 belonging to the genus Fuffitms, of which there is quite 

 a number in our fauna at the present time, but no one of 

 them so small as one of the two I described as coming from 

 tlie caves of the Bermudas. I am firmly convinced that 

 there is a good deal of interesting osteological material in 

 those caves, awaiting the search of the next intrepid ex- 

 plorer, who may be able to enter those which have been 

 hitherto unexplored. 



ADDENDUM. 



As this biief article was about to go to press, several

In the first place, I have received one or two very 

 interesting and kind letters from Mr. Richard Higgins 

 Eurne, Curator of the Osteological Section of the Royal 

 College ol' Surgeons of England, Loudon ; it affords me 

 great pleasure to thank him here for these, and for the 

 very important and useful sketches and photographs he 

 made for me of skulls and skeletons in the collection 

 of which he has charge. These were of various tubi- 

 narine birds, examples of which I could not obtain in 

 tliis country, and which materially aided me in diagnosing 

 the new species I had to describe in the above-named 

 memoir. 



Owing to the fact that the latter cannot now appear for 

 an indefinite length of time, for reasons given me by the 

 Director of the Ameiican Museum of Natural History, 

 I have thought it no more than fair to that museum, to the 

 collectors of the material, and to myself and other avian 

 })alteontologists, that 1 should incorporate a few par (graphs 

 here, setting forth descriptions of the new species of birds, 

 which I found represented in the collection by their skeletal
