COMPARATIVE ZOOLOGY. 



[Jan. 



REPORT ON THE CRUSTACEA. 



By Walter Faxon. 



The chief work on the collection during the past year has been 

 the continuation of the scientific determination and catalogu- 

 ing of the specimens. At the same time, the duplicates are 

 eliminated, and, being identified and labelled, become for the 

 first time fit for exchange. One may form some notion of 

 the condition of the collection, when it is known that in the 

 group of Maioids, answering to 373 catalogue numbers, but 

 forty had been previously identified, mostly by Stimpson. 



The card-catalogue system, previously introduced in other 

 departments of the Museum, has been adopted here, and 

 together with a duplicate-sheet catalogue, in which the objects 

 are entered in a consecutive numerical order, fulfils all 

 requirements. 



A series of recent and fossil Crustacea has been prepared 

 and mounted for the Synoptic collection, and is now on 

 exhibition.
