The following papers were read: On the genns Eusarcns by A. 

 R, Grote and W. H. Pitt. A new marine Fucoid from the Water 

 Lime Group by A. R. Grote and W. H. Pitt. 



The discovery of a marine Fucoid from the Water Lime Group 

 was announced by Mr. A. R. Grote and Professor Pitt, and the 

 type specimen of the species was exhibited. For the species the 

 name Buthotrephis Lesquereuxi Grote and Pitt, was proposed. 

 The specimen is one of the best preserved of the kind yet discovered. 

 No remains of Fucoids appear to be known hitherto from the 

 Water Lime Group of the Silurian. The specimen shows no close 

 affinity to any fucoidal remains known. It is comparable to Butlio- 

 lepis succulens Hall of the Trenton Limestone and to Chondrites 

 antiquus of the Clinton, as well as to C. furcatus of Brongniart. 

 The specimen exhibits a number of branches irregularly mingled 

 by compression. Stem (originally cylindrical) flattened, branch- 

 ing from the base, erect, branches mostly simple, sparingly dicho- 

 tomous, three to four millimeters thick, gradually widening to 

 nearly one centimeter at the very obtuse or round truncate point ; 

 surface smooth. Branches mostly simple from the base, thirteen to 

 fourteen centimeters long. The upper impression of the specimen 

 had been presented to Professor Leo Lesquereux, of Columbus, 

 Ohio, after whom the new plant Avas named.
