298 NEW SPECIES OF BAT — ALLEN. 



The study of measurements has given valuable results iu the study 

 of the human cranium and has enabled anatomists to come to definite 

 conclusions respecting the validity of characters even when derived 

 from scanty and imperfect material. 



No reason can be urged why similar methods may not prove accept- 

 able in describing a new species of mammal. 



Extended observations on a number of examples of allied species en- 

 hance the value of those upon which it is proposed to announce a new 

 one.
