 his recent expedition. A set of these have been secured for 

 the National Collection ; and Mr. Sharpc has exhibited some 

 of the more striking forms at a recent meeting of the Liu- 

 nean Society. We observed fine examples of Turacus gi- 

 ganteus, Corythaix schuetti, Musophaga rossa, and of Buceros 

 atratus, and other species^ which indicate that the fauna of 

 the West Coast extends into the valley of the Welle. Mr. 

 Sharpe has described several species of the collection as new, 

 amongst which are Crater ojms bohndorffi, Sigmodus grisei- 

 mentalis, and Pionias bolmdorjffi.

Dr. F. Leuthner is also making preparations for a natura- 

 list's excursion to South America, and has selected the Upper 

 Orinoco as a locality hitherto little explored, for which he
