Lastly, we come to the primates, an order which embraces 
‘monkeys, the lemurs,and man. The true monkeys are divided 
into two great groups—the old world monkeys and the new 
world monkeys. The new world monkeys are called Platyr- 
-yhine or wide-nosed monkeys. Their dental formula is— 
2; a4; pm. 3; m. 3=36 
The old world or Catarhine monkeys have a dental formula 
the same as man. The dentition of the orang approaches 
very nearly to that of man. The canines are longer, while 
the difference in the premolars and molars is of a trifling 
nature.

with an occasional week-end visit at the May bank-holiday. 
My notes from Blair Atholl were made only at week-end 
visits at the May bank-holiday during the last two years; 
while those referring to Fossoway were made in July and 
the beginning of August of this year (1901). On week-end 
visits I was always accompanied by my esteemed friend T. G. 
Laidlaw of this Society. My practice in going to a locality 
is to carry a copy of Howard Saunders’ List of British Birds 
in my pocket, and tick off each species as it is observed, 
marking any particulars that may be deemed necessary.

_Imay mention a few notes of our journey to Ballinluig, 
as sometimes a good deal can be seen even from the window 
of an express train. Starting from Edinburgh, there is not
