considered as "une variete purement locale" of L. petaurista. 

 L. siGNATA is deemed distinct. L. ascanius with which he 

 unites L. histrio (Reich.), L. melanogenys Gray, L. picturata 

 (Santos), and L. schmidti (Matschie), with which view, with 

 the exception of the last species, most Mammalogists will agree ; 

 L. ERYTHROTis is accepted as a species, as are also L. nic- 

 TiTANS, and L. martini, the latter with L. ludio (Gray), L. 

 melanogenys (Schlegel, nee Gray), and L. stampHii (Jent.), 

 as synonyms. L. cephus, and L. pogonias are considered dis- 

 tinct; L. erxlebeni (Dahlb. et Pucher.), = L. grayi (Fraser) ; 

 L. nigripes Du Chaillu ; L. grayi Fraser ; L. BRAZZiE, and L. 

 CYNOSURA are accepted, and L. griseoviridis (Desmarest), is 

 called L. sahcea Linn., ( !) of which L. engythithea (Gray), is 

 made a synonym. There are descriptions of the species, and 

 the geographical distribution is discussed. Altogether it is a 

 paper to which much thought has been given and betokens a 

 considerable advance in the treatment of the subject.
