MUSEUM OF COMPARATIVE ZOOLOGY. 39 



followed it. Later I attended the session of the Congress at 

 Toronto, as one of the delegates of Harvard University and of the 

 Museum of Comparative Zoology. 



The part of the year devoted to Museum work was largely used 

 in the continuation of the sorting, identifying, and labeling of the 

 collection of trilobites, and the identification of the Canadian 

 material mentioned above. Some time was also spent in selecting 

 a series of Mesozoic fossils for exhibition, and in the identification 

 of the Crustacea in that series. Among the trilobites, all speci- 

 mens belonging to the Illaenidae and Calymenidae, and the Euro- 

 pean species of the Trinucleidae and Conocoryphidae were arranged 

 and labeled, as were also a considerable number of specimens of 

 Asaphidae and Cheiruridae which were overlooked when going 

 over those families last year. 



The following accessions have been received during the year: — 



By donation: — Two trilobites from Dr. CD. Walcott, eighteen 

 Lower Helderberg fossils from Mr. Olaf 0. Nylander, one gastropod 

 from Mr. J. H. Hustis, two trilobites from Mr. A. W. Asmuth, 

 one Trenton trilobite and twelve Brazilian fossils from Mr. 

 Winthrop P. Haynes, one trilobite, and one Arthrophycus from 

 Miss M. R. Rotch, and one slab of trilobites from the Curator. 



By exchange: — One trilobite from Mr. Winthrop P. Haynes, 

 and a collection of unidentified fossils from Mr. L. E. Trout. 



By collection : — Fossils from the Cambrian, Devonian, Missis- 

 sippian, and Pennsylvanian of central Montana, Mr. Winthrop 

 P. Haynes; from the Upper Cambrian and Lower Ordovician 

 near Saratoga, N. Y., Ordovician at Tribes Hill, and Patterson- 

 ville, N. Y., Cincinnati, Ohio, and Richmond, Indiana, and Silurian 

 at Chicago, Illinois, and at Racine and near Milwaukee, Wisconsin, 

 the Curator.
