many cases the fact that specimens had been 

 mounted to the floor or walls of cases, instead of on in- 

 dividual mounts, prevented an arrangement of the new 

 series in anything like systematic order. However, 

 rather than wait until new cases could be built or the 

 old ones remodeled, for which purpose funds were not 

 at hand, the rearranged series are being temporarily 

 gathered together in the most convenient manner, in 

 the hope that a more systematic arrangement may be 

 worked out later. Considerable time mast elapse be- 

 fore the specimens in each series can be properly 

 mounted and supplied with full descriptive labels ; 

 and it is to bridge over this gap and to render in the 

 meanwhile the new arrangement somewhat intelligible 

 to the visiting public that this Guide has been 

 prepared.
