252 Annat.s of the Carnegie Museum. 



Inasmuch as one of the functions of this Museum is the develop- 

 ment of the spirit of research in the field of local history and archee- 

 ology, as well as in the domain of natural history, it has been determined 

 to include in the Annals from time to time papers treating of the early 

 history of western Pennsylvania, and more particularly to make the 

 Annals the medium for the publication of documents which may be 

 regarded as " sources " of historical information. The present volume 

 will therefore contain a paper embodying the records of " The Province 

 of West Augusta," with a historical introduction from the pen of 

 the Hon. Boyd Crumrine, whose familiarity with the early history of 

 the region is well known. This paper will be followed in later issues 

 by the publication of the records of the courts held under the author- 

 ity of the Colony of Virginia in what was known as Yohogania County, 

 which covered southwestern Pennsylvania. These records throw much 

 light upon questions of a historical and genealogical nature. Their 

 existence has been known to but few, and their publication is timely 

 and important from a historical standpoint.

 In order to show how widely some species have been distributed, by 

 means of plant exchanges, the original habitat is given in brackets. 

 Opeas johannina Morelet. (Anjouan, or Johanna Island, of the 



Comoro group.) 

 Opeas goodalli Miller. (West Indies, but originally described from 



examples found in an English greenhouse. )

a circumpolar species.)
