A critical review is made of climatic classifications appearing since 1956, bringing up to date the review of older classifications undertaken by Prof. Taiji YAZAWA. The author mentions that : 1) Determination of the boundaries of climatic regions either by classic or modern climatology is not yet sufficiently rational. Climatic boundaries usually are still far from the actual climatic divides, which exist in the atmosphere itself. 2) Greater emphasis must be placed on daily weather phenomena. 3) For the climatic division of a country, such as Japan, data from all possible stations must be used.
The stratigraphy, palaeogeography, faunas, and crustal movements recorded in the Jurassic rocks of Middle and South America are summerized in this paper. In many areas of Mexico and Andean regions the Jurassic sediments were produced under geosynclinal condition, but the facies, which are generally well characterized by the predominance of calcareous deposits and Tethyan faunas and controlled by three or four sedimentary megacycles, differ in many respects from those of the Pacific coast of North America and many other regions of the circum-Pacific orogenic belts.
