140 REPORT OF NATIONAL ISIl'SEUM, 1893. 



2. A series of groups of cbaracteiistic Xortli American inammals, 

 each confined to a single species, and consisting of several specimens 

 (adult males and females, and young of both sexes, in most instances), 

 accompanied by accessoi-ies, indicating tlie surroundings and habits 

 of the species in a state of nature. 



It is unnecessary in tins connection to give a detailed list of the genera 

 included in tlic family series, as, Avith no great number of exceptions, 

 the entire mammalian fauna of America was represented in this Avay. 

 Only the Xorth American genera of bats were included, as these mam- 

 mals are, for the most part, small, and do not present salient external 

 characters. Tliey would hardly repay, in connection with an exposi- 

 tion, the time and labor which it would be necessary to bestow upon 

 them. The Cetaceans wei^e omitted, as not belonging strictly to the 

 American fauna. 



Among the rarer genera exhibited were Chironectes, ChlamydophoruH^ 

 Xenurus, Elasmof/nathu.s, Lagidium, Murodipodops^ tiolenodon, and 

 Brachyiirus (or Ouaharia). 



Of some of the rarest families, such as J)i)iomyida', no representa- 

 tives could be obtained. Pictures of some of these were introduced. 



A large proi)ortion of the specimens included in this systematic 

 fiimily series Mere taken out of the Museum cases, but it was necessary 

 to purchase a considerable number to till gaps. 



The families shown are as follows:
