jars of Crustacea as well as various lots of local Arachnida, Myri- 

 apoda, etc., received during the year. 



Dr. Witmer Stone collected a large series of Crustacea at Cape 

 May, New Jersey, from which groups were prepared and mounted 

 for exhibition. Bases were constructed representing sand beaches, 

 mud flats, etc., with accessories collected and prepared for the 

 purpose. Some groups of the larger mollusks were also prepared, 

 making eighteen in all, which form an instructive exhibition of the 

 more striking invertebrates of our seacoast. 



Vertebrate Fossils. 



Mr. William Palmer, of the U. S. National Museum, has studied 

 the collection of fossil cetaceans from the Miocene of Maryland and 

 determined many unnamed specimens. He has also borrowed 

 portions of the series for further study. 



Invertebrate Fossils. 



Mr. W. P. Woodring, of Johns Hopkins University, has borrowed 

 the series of unnamed fossils from Bowden, Jamaica, in the Academy's 

 collection and is engaged in studying and identifying them. 



Mr. Joseph Willcox has presented the Academy with a series of 

 specially selected specimens of Miocene and Pliocene mollusks, 

 comprising the most perfect examples obtained by him in his many 

 years' work in the Tertiary beds of the Southern States, from Virginia 

 to Florida. These make a noteworthy exhibit in the museum and a 

 fitting memorial of Mr. Willcox's palseontological researches. 



Herbarium. 



The continued illness of Mr. Stewardson Brown has left the 

 herbarium largely dependent upon the voluntary service of Messrs. 

 Bayard Long and S. S. Van Pelt, who have been in attendance a 

 large part of the year and have given personal attention to such 

 matters as have arisen in connection with the department. 



Mr. Long has cared for the local herbarium as heretofore, has 

 made critical studies of various groups and accomplished a con- 

 siderable amount of local field work. Mr. Van Pelt has devoted 

 himself mainly to the mounting of specimens for the local herbarium, 

 amounting to over 3,000 sheets. 



Miss Ada Allen has been employed in mounting plants for the 

 general herbarium and has prepared 2,000 sheets. 



Mr. Berwynd Kauffman has been employed during part of the
