Amazon River turtle, a Muta-niata turtle, a huye alligator snapper, the largest of tlie 

 Nortli American water turtles, geveral boas, lizards, toads, and froLi;s. An exhibit of 

 lizards will be arranged in i?ome of the wall cases. 



The 2)ermanent installation of insects in tiie hall recently assigned to this grou]i at 

 the western end of the Smithsonian building has progressed to the extent of mount- 

 ing about 2,700 specimens in 20 of the standard boxes occu])ying several ui)right 

 cases. In the labeling of this series attention has especially been called to s])ecies of 

 ]>eculiar habits and to those of most interest to the i)nblic. 



To the display of vertebrate fossils have been added partial skeletons of the large 

 Trlreratoj)s pror-iKK and of the carnivorous dinosaur, .l/^o,sa»rt(,s'. The installation of 

 the Harris collection of invertebrate fossils, in a section of tlierail case of the gallery 

 in the southeast court, has been jiractically completeil. This collection, received in 

 1S98, is one of the finest yet made in the region it represents, being espc<'ially ri<-ii in 

 crinoids, star-fishes, and trilobites, containing of the last group about 600 out of the 

 750 S]ie(nes known fi-om the Cinciimati formation. 



The collections relating to physical and chemical geology have, in jiart, been 

 thoroughly overhauled and rearranged, and about 100 photographs, maps, and other 

 ])ictures illustrative of these subjects have l)een placed on the adjoining walls. The 

 building of galleries in the south-west range made it necessary to n-move for a time 

 the collection of nnnei-als, which, at the close of the year, was being reinstalled after 

 careful renovation.
