? . Antennae much more slender, joints 3-9 longer than 

 broad. 



Length 4^-5, breadth 1-&-2 mm - (<??•) 



Hub. E. Africa, Kashitu in N.W. Rhodesia (H. C. Doll- 

 man : i. 1915). 



Two males and one female are referred to H. hamatus, 

 which is extremely like H. furcatus from the same locality, 

 and is only separable therefrom by the <J -characters : the 

 anterior trochanters are strongly hooked and the intermediate 

 tibiae abruptly, moderately widened from near the base (as in 

 H. platycerus, $ ) ; the anteiior tibiae want the prominent 

 median lobe ; the intermediate femora are somewhat deeply 

 emarginate near the apex ; and the antennae are rather 

 broadly dilated, but much less so than in H. platycerus.

XXXTII. — On Mammals from the Lotver Amazons in the 

 Goeldi Museum, Para. By Oldfield Thomas. 



(Published by permission of the Trustees of the British Museum.) 



As already noted in connection witli the description of the 

 new spiny rat, Lonchothrix e?nilio3, the authorities of the 

 Goeldi Museum, Para, have kindly allowed me the oppor- 

 tunity of examining the series of mammals accumulated by 

 them during the last six years. 



As the fauna of this region is still very imperfectly known, 

 I think it useful to give a list of the whole of the specimens 

 and their localities. 



The majority of the specimens have been collected by 

 Fraulein Dr. E. Snethlage, and it is to her energy and ability 

 in collecting, and to the enlightened generosity of the Trustees 

 of the Goeldi Museum in the distribution of the specimens, 

 that the greater part of our increased knowledge of Amazonian 

 mammals is due. 



A previous paper of the same kind, giving a list of twenty- 

 eight species, was published in 1912 *, while a number of 

 Amazonian novelties leceived from the Para Museum have 

 been described at various times since 1908. 



The regions chiefly concerned in the present series are
