On many of these species, and on other named species which Mr. 



Woods regards merely as varieties of one or other of the foregoing, 



the paper contains numerous observations. Of the folio w^ing species 



the descriptions are not sufficiently complete to allow of the author

Read a notice " On the Economy of the Order Strepsiptera." By 

 John Curtis, Esq., F.L.S. &c. 



Read also a memoir " On the Muscles which move the Tail and 

 Tail-coverts of the Peacock." By G. C. Heming, Esq., M.D., 

 F.L.S. &c. 



Dr. Heming first refers to the mechanism by which the elevation 

 of the feathers of birds in general is effected, either by a contractile 

 power of the cutis vera, or by various modifications of subcutaneous 

 muscles analogous to the panniculus carnosus of certain Mammalia ;

 for this purpose is far more complicated than in any other bird. This 

 apparatus consists of two parts ; the one intended for raising' the 

 caudal vertebrae and the feathers inserted into the groove of the last
