two — one being in the neighbourhood ol Manaos, on the 

 Soh'moes or lower Rio Negro, and tlie other at Villa Braga, 

 on the "Western bank of the Rio Tapajoz, just above the first 

 rapids. At this latter place Fraulein Snethlage made the 

 most important collection of all — quite a number of new and 

 interestin*;: forms occurring: in it. 



Besides Fraulein Snethlage's specimens, the series owes 

 many interesting forms to Senhor F. Lima, one of her 

 keenest and most helpful contributors, 



A series of duplicates, and all types, are generously 

 presented to the British Museum by the authorities at Para. 



In regard to the present collection, special notice may be 

 directed to the rediscovery of the white-nosed saki (^Pithecia 

 albinasa), only previously known from the type, described in 

 1848, and to the numerous interesting novelties contained 

 in it — notably the tuft-tailed spiny rat LonckothiLc emilice 

 and the wliiiisli h&.i Dejxinycteris isahella^ both of these repre- 

 senting new genera, and to the new marmoset Hapale emilice, 

 from the Curn^ River.
