Island, in the mid-Pacific Ocean. The material for this group was 

 obtained through co-operation with the University of Iowa and it will 

 include a striking background painted from original sketches by artist 

 Corwin who accompanied the Iowa expedition. In addition to work on 

 habitat groups, the systematic collection of mounted birds in Hall 26 

 was installed in new cases and entirely relabeled. Two important 

 mammal groups, both with painted backgrounds, have been completed 

 during the year. These are the group of Sonoran Grizzly Bears and the 

 Beaver group. The scene represented in the Beaver group is that of 

 woodland and lake in the practically primeval forest on the estate of 

 Mr. Cyrus H. McCormick (through whose courtesy the specimens were 

 secured) near Champion, Michigan, where the material for the group 

 was obtained. A group of Afr can Buffalo consisting of five individuals 

 is being prepared for the Museum by Mr. Carel E. Akeley. Work on 

 a group of American Bison has commenced and other groups of birds 

 and mammals have been planned. Owing to the large amount of time 

 spent on group work, additions to the systematic series of birds and 

 mammals have been confined to some 30 birds and three mammals. 

 Among the latter is an interesting marsupial, the Banded Australian 

 Anteater Myrmecohius fasciatus. Mr. Heim, the Museum taxidermist 

 in California, has mounted during the year 128 fishes. He also reports 

 having in preparation 43 additional specimens. Taxidermist Heim 

 has also mounted a crab and crawfish group for a case 6' x 2%' and has 

 secured the necessary accessory material. One shark or sawfish 13 feet 

 in length and several fishes more than 3 feet in length are included in 

 this group. In some cases there are from 6 to 10 examples of one species 

 intended to be used later for groups. The assistant in the Division of 

 Entomology has given considerable time during the year to mak- 

 ing life-history groups of insects, three of which have been completed 

 and placed on exhibition. The groups so far completed, as well as 

 those under way, with one exception, represent local forms of the order 

 embracing the butterflies and moths. They are of interest primarily 

 because they illustrate the various stages in the development of an 

 insect having a complete metamorphosis. In the Division of Osteology 

 560 skulls were cleaned for the Division of Mammalogy; 27 skeletons 

 cleaned for the unmounted collection of comparative osteology; 4 skele- 

 tons repaired and remounted; 5 skeletons mounted for the Systematic 

 collection of osteology and 5 skulls cleaned and mounted for the collec- 

 tion of craniology. 



Printing. — The Printing Office shows unusually good results. It 

 is satisfactory to report that not only has there been an increase in the 

 number of labels printed, and all accumulated popy treated, but the
