The intercalary syringeal semi-ring (fig. 1^ )and its accessory plate of cartilage were wanting. In the Woodcock the syringeal box was less expandedthan in the Jack and Common Snipes, but it was similarlycomposed of four fused rings. The most striking pattern ofthis syrinx was the degenerate condition of the intrinsicmuscles (fig. 3, ), which appeared to terminate on thehinder border of the syrinx. As a matter of fact, howeverj,a number of fine tendinous fibres would be found to run tothe normal point of insertion in the middle of the firstbronchial semi-ring. Dr. P. H. Bahr made the following remarks:— The interesting discoveries of Mr. Pycraf t have addedanother to the list of specialized structures for which theScolopacina are remarkable. To my mind, the fact thatthe syrinx of the Jack Snipe [Limnocryptes gallinuld) isprovided with an intercalary bar of cartilage, as Mr. Pycrafthas already pointed out, explains a great deal. Du
