most frequent in shady, more moist spots, often in deep woods. The 

 remaining two species are easily distinguished from the two men- 

 tioned above bj^ the margins of the leaves, which are thin and mem- 

 branaceous, and are folded in over the central portion of the leaf, as 

 illustrated in o, o' and p." 



I can not too strongly commend "Mosses with a Hand-Lens" 

 (price $1.10) prepared with the purpose of giving "by drawings and 

 descriptions the information necessary to enable any one interested 

 to become acquainted with tlie more common mosses with the least 

 IDOssible outlay of time, patience and money." The book contains a 

 key to the genera based mainly on structural characters and one 

 mainly on habitat, also many keys under the genera; copious illus- 

 trations, clear and accurate on ahnost every page of the text and 

 eight full-page plates from drawings by Marj^ V. Thayer; and an il- 

 lustrated glossary of bryological terms. 



MEETING OF THE BIOLOGICAL CLUB. 



The Biological Club met in Zoological lecture room December 3, 

 1900. Prof. Herbert Osborn presided, twenty-six members present. 

 The following papers were presented : 



" Notes on the Saw Brier, and a Rhamnus new to Ohio." 

 " The Waverly Series of Ohio." 



In the first paper Prof. Kellerman spoke of the distribution of 

 the Saw-Brier, Smilax glauca^ in the soutliern part of the State, and 

 exhibited specimens showing its striking variations in form of leaves. 



The southern buckthorne, Hhamnus caroliniana, was observed 

 commonly in Adams County. It also occurs in Brown County. This 

 is the first record for this species in Ohio. Specimens in fruit were 

 exhibited. 



A hackberry was found unlike any form hitherto reported from 

 Ohio. Specimens are in the hands of Rev. E. J. Hill for study and 

 determination. 



Prof. Ball reported leaf variation as occurring commonly in Colo- 

 rado, and that various leaf forms could be observed in climbing a 

 single hill. 



Prof. Prosser, in the second paper, reviewed tlie literature that 

 has been publislied on the Waverly Series of Ohio, and as a summing 

 up gave a list of names with authorities to be used in future in 

 speaking of the formations of this series. These are as follows: 



Beginning above the Huron Shale. 1. Bedford Shale (Newb.) 

 85 feet. 2. Berea Grit (Newb.) 40 feet. 3. Sunbury Shale (Hicks) 

 10-15 feet. 4. Cuyahoga Shale (Newb.) 275-300 feet. 5. Black Hand 

 Conglomerate (Hicks) 40-100 feet. 6. Logan Sandstone (Andrews) 

 115 feet. 



Under the head of personal observations, Prof. Schaffner gave a 

 list of trees and shrubs whicii lie and F. J. Tyler had found cutting 

 off (self-pruning) their own brandies. 



Prof. Kellerman remarked upon the abundance of the red- 

 seeded dandelion in various parts of the state.
