whole class of polyps, both recent and fossil, and must re- 

 main the standard work on this class for many years. It 

 appeared under the name of Milne Edwards alone, M. Haime 

 having died in 1856, but his cooperation in the preparation 

 of the work is fully acknowledged in the preface. 



Since these careful researches of Milne Edwards and 

 Haime have been published, it may be stated that the polyps 

 are known about as thoroughly as any other class. 



A. E. Verrill presented the following catalogue of the 

 birds found at Norway, Maine, containing notes on each 

 species, such as their relative abundance, the season of the 

 year when found, the time of arrival in spring, and when 

 possible, the time of laying the eggs. 



CATALOGUE OF THE BIRDS FOUND AT NORWAY, OXFORD Co.,

BY A. E. VERRILL. 



In the preparation of the following catalogue I have 

 endeavored to give a correct idea of the ornithology of a 

 single locality, but do not offer it as a complete enumeration 

 of all the species that may be found there. It is indeed 

 quite probable that several additional species of the smaller 

 birds, such as Warblers, and Sparrows may be not uncom- 

 mon, and that various others may be occasionally found as 

 rare or accidental visitors. But it seems to me much more 

 important in the study of the geographical distribution of 

 birds, to know the common and most characteristic birds of 

 any region and their relative abundance, than to know every 

 species found there without knowing which are common, 

 and which rare or merely accidental. It is to be regretted 

 that so many local lists have been published consisting 

 merely of an enumeration of names with no indication of 

 those that really belong to the region, in distinction from 

 those that are mere stragglers, belonging properly in some 

 other country. It is also very important to make a distinc- 

 tion between those that are resident at the locality during 

 the whole year and those that are migratory and found only 

 at certain seasons ; and among the migratory ones, those
