118 THE AMERICAN MUSEUM JOURNAL 



of biological interrelationships of animals. The center of interest is a family 

 of meadow mice. They are surrounded on three sides by ^ arious charac- 

 teristic enemies — skunk, weasel and cat among the mammals, hawks and 

 owls as representatives of birds, and the black snake among reptiles. In 

 the remaining space are shown the food organisms to which the meadow 

 mouse stands in the position of an enemy. 



Mr. C. W. Leng has put his valuable collection of "long horned" 

 beetles at the Museum's disposal for use in filling gaps in its collections. 

 This means a gift of some 870 specimens covering nearly 300 species not 

 hitherto acquired. 



Mr. John A. Grossbeck, who has been specializing for some time on 

 the Geometridje, has given to the Museum his entire collection of these 

 moths in addition to the series previously donated. This gift places the 

 American Museum in the front rank as regards this division of Lepidoptera. 

 The collection includes about 6000 specimens among which are more than 

 150 types. 



The Museum's new members during the year numbered 349, bringing 

 the total membership on December 31, 1911 to 2,656. About 250 new 

 members have been added to the mailing list since January first. 



The Museum has recently obtained by exchange with the University 

 of Cambridge, England, some rare ganoids, the eel-shaped Calamoichthys 

 calaharicus, which fill gaps in the synoptic series. The same exchange 

 provides specimens of the young of the African lungfish, Protopterus 

 annedens. The latter is an important addition to the Museum's series of 

 growth stages of lungfishes, which was also recently enriched by a large 

 collection of young Ceratodus from Queensland. 



The Annulate group has recently been completed. It displays a number 

 of marine worms and worm tubes in their natural biological settings, to- 

 gether with hermit and fiddler crabs, whelk, scallops, minnows and other 

 organisms which live in the mud or amid the eelgrass of shallow sea wy.ter. 

 The group shows three sections: Above is the ocean as man sees it with the 

 harbor of Woods Hole, Massachusetts, in the distance; below this, the sea 

 as aquatic marine animals know it, where are seen, reproduced in wax or glass, 

 the marine forms living there; and still below, a section of the sand and mud 

 at the bottom of the sea with its population of burrowing animals. The 

 group correlates with an adjoining case of annulates arranged in systematic 

 series, and shows in natural size, living position and natural habitat many 

 of the same species displayed in the case as enlarged models for structure 

 study.
