MUSEUM OF COMPARATIVE ZOOLOGY 9 



Serow, Capricornis sumatrensis milne edwardsi, shot by Mr. 

 Zappey at Tachienlu, and a gift to the Museum from Mr. J. E. 

 Thayer. Mr. Zappey has also accomplished in a most satisfactory 

 way a large amount of taxidermic drudgery. 



Since April, 1912, Mr. J. D. Sornborger has worked conscien- 

 tiously upon the osteological specimens received in recent years. 



As for several years, assistance in addition to the Museum staff 

 has been employed, from time to time, for the care and develop- 

 ment of the research collections. Dr. G. M. Allen, as in recent 

 years, has worked for three days of each week upon the collection 

 of mammals. He has completed a revision of the collection of 

 skins; with the exception of a few recent accessions, the entire 

 series is arranged and card catalogued. Dr. Allen has also begun 

 the incorporation of the fossil Mammalia with the osteological 

 specimens of recent forms. Two papers, the result of Dr. Allen's 

 work on the collection are listed on p. 42, 43. 



Mr. W. F. Clapp's work upon the Mollusca has been confined 

 in large part to the North American Pulmonifera, and to such aid 

 as he could give Dr. de la Torre in the revision of the Cuban land 

 shells. Mr. Clapp's great success in collecting has been referred 

 to. 



Since October, 1911, Miss Elvira Wood has worked upon the 

 collection of fossil crinoids. This collection, with the exception 

 of the Camera ta, has been rearranged according to the 1900 

 English translation of Zittel; the classification of Wachsmuth 

 and Springer has been used for the Camerata. With the rear- 

 rangement, the work of identification, verification of previous 

 identifications, and the relabeling of the specimens has been 

 effected. Many specimens have been developed, and others 

 repaired. All the types and figured specimens have been com- 

 pared with the original descriptions and figures, and catalogued. 



Three new cases have been built in the exhibition halls and the 

 many new accessions to the research collections have necessitated 

 additional cases for the collections of echinoderms, insects, and 

 birds. In two of the new cases in the gallery devoted to the North 

 American fauna, the invertebrates and lower vertebrates have 

 been rearranged. The improved methods of mounting fishes for 

 exhibition have been very marked during recent years. With due 

 care these methods prove satisfactory for large and medium sized 

 specimens, but have failed hitherto for small fishes. Recently, 

 however, Mr. Nelson has mounted specimens of the Redside 

 Darter, Boleichthys fusiformis, less than two inches in length,
