Some Unusual Ceramics from Esmeraldas, Ecuador

In 1940, while on a commission for the Ecuadorian Government to the site of La Tolita in the province of Esmeraldas, Ecuador, the author had an opportunity to examine and photograph a few specimens in the collection of Sr. Yannuzzelli. Sr. Yannuzzelli maintained a ranch at the archaeological site of La Tolita which is located a few miles up the Rio Santiago from the coastal town of Limones and is not far from the Colombian border. Several large flat top mounds (Fig. 56, 1) and about 25 increasingly smaller ones comprise the present site. It had been visited about 30 years previously by both Uhle and Saville, but neither one conducted adequate excavations there. It is a favorite site for local inhabitants to pan gold, and in 1940, Sr. Yannuzzelli was actually engaged in carrying out extensive, large scale, placer mining operations within the archaeological zone.

Geology of Pacific Coast of Ecuador: ABSTRACT

The general geology of the Pacific Coast of Ecuador is described. The area is approximately 500 miles north and south, ranging from the Peruvian border on the south to the Colombian border on the north. The formations include Cretaceous, Tertiary, and Recent sediments. The coast is divided into three areas; Northern, Central, and Southern. An attempt is made to describe the structural and depositional conditions present in each area. The paper is illustrated by a general map, geologic maps, correlation charts, columnar sections, and cross sections. End_of_Article - Last_Page 2316------------

Notes on Some Fungi from Colombia

In the spring of 1934 the writers spent some time in South America, chiefly in Venezuela, making mycological explorations and collecting specimens. While spending some time in the State of Tachira, Venezuela, the nearness to the Colombian border tempted us to cross over and do a bit of collecting there. The specimens here reported were collected in the vicinity of Cucuta, Department Norte de Santander, Colombia, on May 11, 1934. Our knowledge of the fungous flora of Colombia is well presented in a paper entitled Mycological Explorations of Colombia by Carlos E. Chardon and Rafael A. Toro, Journal of the Depart? ment of Agriculture of Puerto Rico 14: 195-369, 1930. Further information regarding the Uredinales there is to be found in an Annotated Index of the Rusts of Colombia by F. D. Kern, H. W. Thurston, Jr, and H. H. Whetzel, Mycologia 25: 448503, 1933. We are indebted to the administrative officers of the University of Puerto Rico, especially Chancellor C. E. Chardon, for making possible our trip to South America and to various officials and friends there for assistance and courtesies which were accorded to
