account of the nuiiu geological features of certain regions of 

 that country. The first to be described was the region of the 

 Panipa, or grassy treeless plain, which stretches from Rio de 

 la Plata to the Andes. . It possesses a characteristic surviving 

 fauna and traces of a wonderfully rich extinct one. A 

 description was next given of the region of the Gran Chaco, 

 a great wilderness, which, lying to the west of the River 

 Paraguay, forms the northward continuation of the Pampa. 

 The four great types of scenery characteristic of this region 

 — the river, the forest, the savannah, and the swamp — were 

 described, and their special biological features defined. The 

 rivers of the Chaco are mostly narrow, tortuous, and somewhat 

 sluggish streams. In the neighbourhood of the large rivers, 

 the forests are luxuriant, and resemble those of Paraguay and 

 Brazil; but in the interior of the Chaco they are scrubby, and 

 are cut up into islands scattered about in the savannah. The 

 savannahs are grassy plains dotted over with fan-palms. The 

 swamps are characterised by their dense vegetation, with pools 

 and lagunas of open water here and there. During the lecture 

 many beautiful lantern slides illustrative of South American 

 scenery were exhibited on the screen, and at the end a few were 

 added to show some of the tyjjes of the red-skinned inhabitants 

 of the Chaco. 



Dr. T. Beath Henderson moved a vote of thanks to the 

 lecturer and his assistant, which was heartily accorded by 

 a large and ajjpreciative audience. A very extensive collection 

 of specimens, part of which were preserved in bottles and part 

 mounted for microscopical examination, was arranged for 

 exhibition in the large hall, and examined with much interest.

Mr. D. A. Boyd, President, in the chair. 



The chairman referred to a movement for the institution of 

 a Representative Council of Natural History Societies in 

 Glasgow and throughout the district included within the Clyde 

 Area. He indicated some of the obvious advantages which 

 would be derived from such an association, and recommended 

 that the Society should exjiress its approval of the project by
