The table in the Naples Zoological Station hired by the British Associa- 

 tion has been occupied during the past year by Mr. James F. Gemmill, 

 Mr. H. M. Vernon, and Mr. J. Parkinson. 



Mr. Gemmill, who occupied the table from August 20 to November 12, 

 was engaged in investigating certain points in the anatomy of the osseous 

 fishes. 



Mr. Vernon held the table from October until the middle of January, 

 and continued his investigations on the conditions of animal life in marine 

 aquaria, with a view to determine the relations existing between marine 

 animal and vegetable life. Mr. Vernon also made careful experimental 

 researches on the relations between the hybrid and parent forms of 

 echinoid larvas. 



Mr. Parkinson occupied the table from October 25 to April 26, and 

 devoted himself to the investigation of the variation of certain lamelli- 

 branchs. 



Each of these gentlemen has furnished a report upon the work done, 

 wliich will be found appended. 



Your Committee has again to remark with gratitude on the kindness 

 of Professor Dohrn in allowing the terms of occupancy in these cases to 

 run concurrently, at least during part of each period. Without this 

 courteous treatment on the part of Professor Dohrn, the Committee would 

 have been unable to meet the wishes of the several workers. 



An application for permission to use the table during the ensuing year 

 has been received from Mr. H. Lyster Jameson, for the purpose of 

 making investigations on the anatomy of the Gephyrea. He wishes to go 

 to Naples at the beginning of October and to remain six months. This 

 application is recommended by your Committee, and they trust that the 

 General Committee will sanction the payment of the grant of lOOZ., as in 

 previous years, for the hire of the table in the Zoological Station at 

 Naples. 



The progress of the various publications undertaken by the station is 

 summarised as follows : — 



1. Of the 'Fauna und Flora des Golfes von Neapel ' no monograph
