Show 152 MR. A. H. GARROD ON THE [Mar. 2, 1. SARCIDIORNIS MELANOTA (Gm.): Sclater, Rev. Cat. Vert. p. 241. To Mr. Eyton, who established the genus to which this peculiar bird belongs, the visceral anatomy was unknown ; and I am not aware of any subsequent description of it having been published. A pair were purchased by the Society on the 18th of September, 1867, the female of which died on the 10th of March, and the male on the 18th of October last year ; these are the specimens which I have examined. In both sexes the diameter of the trachea diminishes slightly at its lower extremity before it again expands a little to end in the syrinx. As in birds generally, the tracheal rings are complete and notched in the middle line before and behind, in such a way that where they meet the two halves*overlap and are overlapped respectively by the rings above and below them. The lower tracheal rings, however, in both sexes are much thinned in front, as is the case in the male of Harelda glacialis*; they are not ossified together. In the male Sarcidiornis melanota (fig. 1) there are 20 anterior, Fig. 1. Fig. 2. Fig. 3. Fig. 1. Lower part of trachea oi Sarcidiornis melanota S-Fig. 2. Ditto of Sarcidiornis melanota 2 • Fig. 3.
