470 Dr. P. L. Sclater on Testudo chilensis. 
XLIX.— Remarks on the Animals lately described by Dr. Gray 
as "Testudo chilensis sg Ateles Bartlettii. By P. 
ScLATER, M.A., Ph.D., F.R.S., Secretary to the Zoological 
Society of London. 
I Aw no lover of controversy ; but taking, as I am bound to 
do, special interest in the correct determination of the animals 
that have lived in the gardens of the Zoological Society of 
London, I must ask the Editors of the * Annals’ to allow space 
for a few remarks upon the tortoise and spider monkey re- 
cently described by Dr. Gray in this journal, under the names 
estudo chilensis and Ateles Bartlettir, female. 
Testudo chilensis is described by Dr. Gray in the ‘ Annals’ 
for August last (anteà, p. 190) as a “ new eee " tortoise ; 
but, in the first. place, it is = new, and, in the second place, 
it is, as I believe, not Chili 
That it is "x new, but mei hitherto incorrectly deter- 
mined, has been already admitted by Dr. Gray himself, in his 
second note on this subject (anteà, p. 428). This Tortoise was 
ae discovered by D’Orbigny on the Rio Negro, in the south 
he Argentine magn cii but referred by him and by Messrs. 
iine and Bibron (Erp. Gén. ii. p. 79) to Testudo sulcata, 
though the latter MS expressly notice the principal cha- 
racters in which the single specimen examined differs from 
that African species*. 
Burmeister, in the second volume of his ‘ La Plata-Reise,’ 
also follows the determination of Duméril and Bibron, but 
gives us the additional information that this pire “is found 
near Mendoza, iud all over thé Pampas " (J. c. 
In his excellent vus on the geographical distribution of 
the Testudinata (Mém. Ac. St. Pét. 7th ser. vol. viii.), 
Strauch discusses at full length the alleged occurrence of Tes- 
tudo sulcata in Africa and South America as an extraordinary 
exception to the general law of distribution of these animals, 
and comes to the conclusion that either the African tortoise 
“Dans Vhorizontalité un peu moins marquée des plaques dorsales, et 
dass la présence d’un petit bord tranchant le long des flanes qui sont au 
contraire arrondis or les autres.” 
+ Dr. Peters has most kindly obtained from the Museum of Halle and 
examined for me Burmeister’s specim ^" and has no doubt of their being 
not Testudo faces but the so-called T. chilensis,
