Mammals and Birds 89 



years of service and familiarity with the collection of mammals 

 had made him invaluable and difficult to replace. 



The cataloguing of the recent accessions of birds has been 

 continued, including some 3,500 specimens from South Amer- 

 ica, also the Congo collection. The nests and eggs have been 

 brought into better order and the additions of recent years duly 

 incorporated. 



The rearrangement of the exhibition collection of mammals 

 and additions of new groups have been continued with excel- 

 Exhibition * ent resu ^ s j especially noteworthy in the revised 

 Collection Hall of Primates. 



Practically all the single specimens have been removed from 



their conspicuous polished cherry pedestals, those mounted 



on limbs being placed directly on the back of the 



case and those walking on all fours placed on 



inconspicuous rock bases. 



Under the supervision of Mr. Peters, the group of Orangs 

 has been rearranged and the conventional foliage — the best 

 that could be obtained thirty-five years ago — replaced by ac- 

 tual reproduction of the leaves of the Durian. 



Good progress has also been made in the Hall of North 

 American Mammals. Aside from the fine group of Timber 

 Wolves, a number of single specimens of characteristic mam- 

 mals have been added to fill gaps in the series. 



Steady improvement is being made in the systematic series 



of birds by mounting desirable specimens received from the 



Zoological Park to fill gaps in the series or to 



replace similar, but poor examples, while many 



of the old, but valuable birds, have been skilfully remounted 



by Mr. Engel. 



The entire collection, and the cases, have been cleaned, and 

 the actual condition and appearance of the collection are bet- 

 ter than ever before.
