of which the inner is the longer; the hand smooth and not 
dilated. 
The second, third, and fourth pair of legs are short com- 
pared with the chelipeds, the second a little longer than 
the third, and the third than the fourth; the ischium has a

Of the species heretofore described it is most like Dyptachus 
intermedius (A. M.-E.), but it differs from it in having a 
spiny rostrum, and very unequal flagella on the antennules. 
The carapace also is more quadrangular in shape. 
LXVII.—On Mammals obtained by Mr. Alphonse Robert 
on the Rio Jordio, S.W. Minas Geraes. By OLDFIELD 
THOMAS. 
THE British Museum has recently received from that admir- 
able collector, Mr. Alphonse Robert, a collection of mammals 
obtained by him on the Rio Jordao, in the district of Araguary, 
S.W. Minas Geraes, and it has proved to be of such interest 
as to deserve a general account. Mr. Robert had already 
sent collections from Piqueté, Cruzeiro, and other localities 
near the borders of Southern Minas and Eastern Sao Paulo, 
collections which proved of the utmost value in identifying 
species described by Wagner and other older authors, but 
which had not contained any novelties beyond the Sccurus 
Ingrami described in a previous number of this Journal *. 
The present collection, however, came from a less-known 
region and included quite a number of new forms. It was ©
