The Secretary exhibited comparative drawings of the heads of 

 two North-American Swans (Oygnus americanvs and G. buccinator^ 

 of which Mr. F. E. Blaauw, C.M.Z.S., had lately received living 

 examples in Holland, and read the following extract from a letter 

 received from Mr. Blaauw on this subject : — 



" I send you a water-colour drawing of the head of the Gygnus 

 americanus which I received in a living specimen some weeks ago. 

 For comparison I have had the head of G. buccinator drawn on the 

 same paper. You will notice that the yellow part of the bill of 

 G. americanus is of a pale yellow, more or less mixed with blackish 

 spots ; moreover, the line formed by the feathers of the front in 

 C. americanus goes in a nearly straight line from the eye to the 

 frontal base of the bill, whilst in C. buccinator this line first goes a 

 little forward, before it bends upward to the front. In both birds 

 the edge of the mandibles, especially of the lower one, near the 

 corner of the mouth, is of a pinkish colour. The line formed by 

 bill and head is also quite different in G. americanus. On the 

 whole, C. americanus is of a slighter build than G. buccinator. The 

 plumage in my G. americanus is of a pure white, without addition 

 of yellow or greyish feathers on the head." 



The following extracts were read from a letter addressed to 

 the Secretary by Mr. 4i. Trimen, F.Z.S. (dated South-African 

 Museum, Capetown, June 25, 1894), with reference to Dr. A. G. 

 Butler's remarks on his paper on Butterflies from Manica : —
