the salient features in the evolution and classification of these groups and 
said, in abstract: The serpents are undoubtedly derived from lizards. 
Some of the latter possess grooved teeth, and a series may be arranged among 
them showing the progressive decline in morphological and functional impor¬ 
tance of the limbs. This series begins with such a form as the dragon lizard 
( Basiliscus ) with long hind limbs and which, in running, carries its body 
clear above ground. In other forms the limbs are not as well developed, so 
that the body rests entirely on the ground (. Heloderma ) or may even be 
dragged ( Cyclodes ). A connecting link between serpents and lizards was 
exhibited ( Ophisaurus ). This form looks exactly like a snake, but is a true 
lizard. In the serpents there are no traces of external limbs, though with the 
boas and pythons internal ones are present. The jaw is greatly distensible, 
and true grooved or canaliculated fangs are developed among many. A 
number of interesting points in the habits of the serpents were brought out. 
Mr. Andrews gave an account, illustrated by lantern slides, of his ex¬ 
periences while at the whaling stations on the coast of Vancouver Island and 
southern Alaska. The paper was devoted to a discussion of the habits of 
some members of the family Balsenopteridse and of the modern methods 
employed in their capture. Many reproductions of photographs were 
shown on the screen illustrating the manner of spouting, diving and feeding 
of these whales. The speaker dwelt especially upon the peculiar manner in 
which the nasal region is protruded during respiration and upon the atti¬ 
tudes assumed by the animals when diving. The method of feeding and the 
movements during play were also discussed. 
The Section then adjourned.
