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,
