Of the three names given by Desmarest to the pichiy armadillo, the 
latest, minutus, is found most frequently in literature while the earliest, 
pichiy, seems to have been entirely overlooked. The name minutus 
has of late been replaced by ciliatus of Fischer, but this should give 
way to pichiy. A further synonym, rarely cited, is Euphractus mar- 
ginatus Wagler, also based on Azara. 
Cavia tschudii arequipse nom. nov. 
Cavia tschudii pallidior Thomas, Ann. & Mag. Nat. Hist., (8), xix, p. 158, 
January, 1917 — not Kerodon niata pallidior Thomas 1902 [= Cavia {Monti- 
cavia) niata pallidior]. 
If Monticavia be regarded as no more than a subgenus of Cavia, then 
C. t. pallidior, 1917, is preoccupied by K. n. pallidior, 1902, and re- 
quires a new name. Mr. Thomas, who proposed both names, treats 
Monticavia as a full genus and therefore would make no change, but 
for those who wish to be consistent in opposing the recognition of 
slightly characterized groups as full genera, action as above is demanded

Although Allen in 1895 (1. c.) called attention to the priority of 
Kerr’s name australis for the Falkland Island dog, the name has not 
been brought into use. Even Allen himself in 1905 (1. c.) fails to men-' 
hion it and uses antarcticus of Shaw in discussing the subgeneric posi- 
tion of the species. Since its basis is identical with that of antarcticus,
