similar to the " marsupial " bone of the Implacental Mam- 

 malia and its corresponding fibrous representative in certain 

 Carnivora, 



2. Heteralocha*. — In 1872 the true affinities of the Huia 

 bird were quite uncertain, many authorities placing it amongst 

 the Hoopoes (Upupidse) . From an examination of the speci- 

 men that lived in the Zoological Society's Gardens, Prof. 

 Gari'od was enabled to show that it was truly Passerine, and 

 not only so, but in many respects so peculiarly Stu7'7iinef as 

 to entitle it to a place '' at the head of the family." 



3. Steatornis J . — Besides the myology and visceral anatomy, 

 the ptcrylosis, skull, and syrinx (which is " bronchial ") are 

 particularly described and figured. The result arrived at, 

 as regards the systematic position of Steatornis, is that it 

 must form a family by itself, with strong affinities to the Owls, 

 Caprimulgidse, and Coraciidse and their allies. 



4. Columbce § . — In these papers the number of the rectrices 

 (varying from twelve to twenty in different genera), together 

 with the presence or absence of the oil-gland, of the casca, 

 and of the ambiens muscle, is recorded in a large number of 

 forms, and, from the various combinations of characters so 

 obtained, an attempt is made to divide up the group of 

 Pigeons, in which are included the Pteroclidse, in a more 

 natural way than has hitherto been done. Attention is also 

 called to the characteristic form of the humerus in these 

 birds!, as well as to the peculiar form of the gizzard in the 

 genus Ptilopus, there being here four crushing-pads, instead 

 of two as in all other birds, includiug even Treron.

t Mr. Sharpe must, we fear, have overlooked this paper of Prof. Gar- 

 rod's, as he still retains Heteralocha amongst the Corvidas (Cat. Birds, iii. 

 p. 143), quite in opposition to the conclusions above stated.
