 five years. 



The authors appear to have unearthed some very unique 

 material, which is unusually well preserved and well adapted for 

 critical study, as evidenced by the illustrations of internal struc- 

 ture and, if the interpretation of the facts are correct, some of 

 the results attained are somewhat startling. For example, cer- 

 tain leafy twigs, identified from their external characters as 

 Frenelapsis gracilis Newb., Widdringtonites Reichii (Ettingsh.) 

 Heer, Brachyphyllum macro car -pum Newb., and Sequoia Reichen- 

 bachi (Gein.) Heer, were sectioned and determined to belong in 

 the Araucarineae, instead of in the Sequoiineae and Cupressineae. 

 The sections of these twigs shown in the illustrations are un- 

 doubtedly araucarineous in their affinities ; but the whole im- 

 portance of this fact is dependent upon whether they were 

 correctly identified from the external characters in the first 

 instance. 



Among the many new genera described it is of interest to note 

 that the name of the owner of the clay pits, and that of the 

 locality, is recognized in the name Androvettia statenensis, while 

 our fellow member, Mr. William T. Davis, is remembered in 

 the new species Strobilites Davisii, based upon a well-preserved 

 cone, collected by Mr. Davis. 



Our museum material was freely utilized in the preparation 

 of the memoir, and most of the figured specimens showing 

 external characters are in our collection. 



It is the most exhaustive and best illustrated contribution to 

 our local science that has yet been issued from any source, and 

 the authors are to be complimented on the thoroughness with 

 which they have carried out their investigations.
