obtained during the voyage of the ' Emerald ' would be made 

 to a subsequent meeting of the Club, probably when Dr. Percy 

 Lowe, who was Sir Frederic Johnstone^s private medical 

 attendant, returned to England. Dr. Lowe was an excep- 

 tionally keen naturalist, and had made a beautiful collection 

 of birds during the voyage, and Dr. Sharpe was convinced 

 that the Club would extend a very hearty welcome to his 

 young comrade, who had been such an enthusiastic collector 

 during the voyage of the ' Emerald/ 



Dr. Bowdler Sharpe then read the following paper : — 



" I exhibit a series of seven specimens of Sula coryi, 

 Maynard ; obtained in Little Cayman Island. Two of the 

 birds obtained on our first landing were old white individuals 

 of the third or fourth year. We also obtained four birds of 

 the second year, brown with white tails : one younger bird, 

 brown, with a tail broivn for the most part (only the two 

 centre tail-feathers being entirely ivhite). 



" Sula coryi is undoubtedly closely allied to S. piscatrix, 

 and may yet prove to be identical with that species. At 

 present its chief claim to specific distinction rests on some 

 differences in*the colour of the bare face of the adult 

 and in the possession of a white-tailed brown plumage in 

 the immature birds ; but certain specimens in the British 

 Museum collection have been pointed out to me by Mr. 

 Ogilvie-Grant which seem to indicate that S.piscatrix passes 

 through a similar stage of plumage. 



tc Mr. Maynard has described the Cayman Gannet as Sula 

 coryi in his ' Contributions to Science,' an octavo volume 

 published by himself at Newtonville, Mass. (pp. 40-57, 

 pi. i.). He has given an excellent account of the habits of 

 the species, which breeds extensively on the island of Little 

 Cayman and at the east end of Cayman Brae. I do not con- 

 sider his estimate of 10,000 birds on the former island beyond 

 the mark. The colour of the bare face given in plate i. of 

 Mr. Maynard's article is, however, totally at variance with 

 our experience, both in respect to the adult and the young 

 birds, and the difference in colour between those obtained bv
