Irregular Publications 



In the interest of exact bibliography, the Society takes cognizance of all pub- 

 lications issued wholly or in part under its auspices. Each author of a memoir 

 receives 30 copies without cost, and is permitted to order any additional num- 

 ber at a slight advance on cost of paper and presswork ; and these reprints are 

 identical with those of the editions issued and distributed by the Society; but 

 the cover bears only the title of the paper, the author's name, and the state- 

 ment [Reprinted from the Bulletin of the Geological Society of America, vol. 

 — , pp. — , pl. — (Date)]. Contributors to the Proceedings and "Abstracts of 

 Papers" are also authorized to order any number of separate copies of their 

 papers at a slight advance on cost of paper and presswork ; but such separates 

 are bibliographically distinct from the reprints issued by the Society. 



The following separates of parts of volume 28 have been issued :
