 genera Tahanus and Pangonia has been prepared and notes 

 have been made on the literature of the Culicidfe. 



Vermes. — The whole of the spirit collection has been

 kind assistance of Mr. A. E. Shipley, who has determined the

 Vermes obtained during the year have been named and 

 incorporated.

 been mounted afresh, and various explanatory labels have 

 been added. A fine example of a large mass of Favia has 

 been mounted. A photograph of a coral-reef in the New

 for the galleries. A fine specimen of Gorgonella umhella 

 has been mounted in a separate frame.

 tions of Brachiopoda and Tunicata, consisting of dried speci- 

 mens and specimens in spirit, have been arranged, and
