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

 Solimoes or lower Rio Negro, and the 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 

 interesting 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 .-eries of duplicates, and all types, are generously 

 presented to the British Museum by tho authorities at Para. 



In regard to the present collection, special notice may be 

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

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

 1848, and to the numerous interesting novelties contained 

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

 and the whitish bat Depanycteris Isabella, both of these repre- 

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

 from the Cuma" River.
