 The progress of this work was arrested after tbe completion of the 

 portion relating to the educabilian mammals by the iusufficiency of 

 the material at the hand of the author and his inability to examine the 

 anatomy of many forms of the Cheiroptera, which immediately followed 

 the Educabilia in his Arrangement. 



The classification therein presented is therefore now for the first time 

 attempted to be justified by the exposition of the characters distinctive 

 of the various groups, but in one respect a deviation has been made 

 from the arrangement cited. Therein the author, following the tabular 

 scheme published some years before by Professor Peters, had the idea 

 of dividing the Insectivora vera into two primary groups : — (1) those 

 without a cajcum {i. e., Soricoidea, Erinaceoidea, Centetoidea, and Chry- 

 sochloroidea), and (2) those provided with a well-developed ctecum 

 [i. e., Macroscelidoidea) : again, the former group was sabdivided into 

 those with the molars bearing two triangles, or corresponding areas, on 

 the one hand, and, on the other, those bearing single triangles. And this 

 seemed then to be justified by the physiognomy of the forms contrasted 

 as well as by the characters already exposed.* 



A renewed consideration, however, has convinced the author that the 

 characters then regarded as paramount are less suggestive than those
