grounds " for these and other water-birds. Nine of the 

 eighteen members of the Heron-family that are found in North 

 America are met with in this district and four have been 

 detected breeding there. The most abundant species is the 

 American Night-Heron (Nycticorax na>vius), to which the 

 author has paid special attention ; but the other Herons are also 

 specified and their habits described. The paper is illustrated 

 by several photographic plates of nests, eggs, and young.

The articles in this part are almost entirely of local 

 interest ; but the first of them is an account of the life and 

 work of the well-known ornithologist J. K. Townsend, who 

 not only visited the Western United States in company with 

 Nuttall and discovered several new species of birds, but also 

 proceeded with the same companion to the Sandwich Islands, 

 aud subsequently touched at Tahiti and Valparaiso.

Mr. Clarke's final Report summarises the movements on 

 migration of the Starling and the Rook, those of the former 

 species being singularly varied and not confined to any par- 

 ticular season, while the latter for the most part seeks our 

 shores in autumn and departs in spring, when not a resident. 

 Every ornithologist will regret that such excellent work 

 should have reached its final stage, though doubtless the 

 results in the case of further species would not have led to 

 an extension of our knowledge commensurable with the labour 

 required. We can never be too thankful to Mr. Clarke for his 

 work, admirable alike iu its clearness aud accuracy, while, as
