YITI. — On some rare Amazonian Mammnh from the 

 Collection of the Para Museum. By Oldfield Thomas. 



(Puhlished bj- permission of the Trustees of the British Museum,) 



By tlie kindness of the authorities of the Para Museum I 

 have aoain been permitted to examine some rare mammals 

 which have come into the possession of that institution either 

 from their collectors or from the Para Zoological Gardens, 

 which are kept in conjunction with the Museum. 



Notable among these latter is the truly remarkable form, 

 intermediate between the monkeys and marmosets, described 

 as CalUmico snethlageri by Ribeiro, and referred to below 

 under the heading of CalUmico goeldii. 



The new genus of bats — Cyttarops — is also a most inter, 

 esting discovery.
