II. " On the Secondary Carpals, Metacarpals, and Digital Rays 

 in the Wings of existing Carinate Birds." By W. K. 

 Parker, F.R.S. Received January 11, 1888. 



In a paper " On the Morphology of Birds," already sent in to the 

 Royal Society, but not yet published, I have described certain addi- 

 tional parts in the wings of Gallinaceous birds. 



One of these lies on the radial side of the first metacarpal; the 

 other two are on the ulnar side of the second and third metacarpals. 



These parts, which at first caused me considerable surprise, being 

 wholly unexpected by me, are only part of what I have since found 

 in other families. 



During the past year I have worked out the development of the 

 skeleton in the Duck tribe ("Anatidge "), in the Auk tribe ("Alcidas"), 

 and in the Gull tribe (" Laridse "), and to some degree in some other 

 families. The subject appears to me to be of great interest, and I 

 have, through various English and American friends, obtained many 

 scores of embryos and young birds, &c, that I may be able to trace 



* This line is seen as a pretty bright line in the spectrum of the Limerick 

 meteorite, but its origin has not yet been determined, although comparisons hare 

 been made with most of the common elements. So far, it has not been observed in 

 any other meteorite.
