Report of Society's Meetings. 203 
rapids where there were said to be present the remains 
of craters of extinct volcanoes, is worthy of mention, in 
that the formation was due to igneous action (volcanic) 
so commonly to be met with over different parts of the 
colony, though the crater-like depressions were attribut- 
able to the secondary action of denudation, rather than 
to the primary igneous disruption. The longer expedi- 
tions along the Mahaicony and Abary creeks were 
undertaken chiefly for procuring specimens of the little 
known bird, the Fin-foot (Heliornis fulica), examples 
of which were required for dissection in order to deter- 
mine its real affinities. Owing to the extremely wet 
season the special bird was not met with along the Abary, 
though later on, they were secured along the Mahaicony. 
On both trips, however, large numbers of desirable spe- 
cimens of many different classes were procured and 
preserved — though the wetness of the season greatly 
hampered one's operations. 
Acquisitions. — During the year a very considerable 
number of specimens have been acquired by presentation, 
some of which are extremely interesting in character. 
Various valuable specimens have also been purchased, 
the most important of which is a named set of several 
species of birds, collected in the Rupununi district and 
prepared by the noted bird collector, Mr. Henry Whiteley. 
Many others such as rare land boas, rare tortoises, a fine 
specimen of ornamental feather work, and rare and 
desirable specimens of birds, insects, and fishes, together 
with a set of Indian or native pottery, have also been 
thus acquired. Some valuable old colonial coins, such 
as " cut bits" have also been secured from Mr. Fred. 
McConnell in exchange for duplicate skins of birds.
