426 PROCEEDINGS OF THE ACADEMY OF [1887. 



The collections in the department of Invertebrate Paleontology 

 have received a number of accessions during the year, but none of 

 very great importance. Attention is called in the report of the 

 Curators to the addition of a number of new cases to the main floor 

 of the Museum, which will now permit of the definite location of the 

 Academy's share of the extensive series of fossils collected in Florida 

 in the early part of last year, and which, during study, had been 

 temporarily deposited in the room pertaining to Ethnology and 

 Archaeology. The arrangement of a synoptic geological and paleon- 

 tological collection, designed as a "key" or practical manual for the 

 student, is also indicated in the Curator's report. 



The collections in general have been studied by a number ot 

 students from the city schools, and material from them has been sent 

 to Prof. R. P. Whitfield, of New York, to assist in the preparation 

 of an extensive work on the fossil invertebrate fauna of the State of 

 New Jersey. 



Very respectfully, 



Angelo Heilprin, 

 Prof, of Invertebrate Paleontology.
