LOESS OF PECZEL, HUNGARY 
287 
Usually the yellow and gray loesses are quite sharply sep- 
arated, but at some points they intergrade within a band a few 
inches in width. It is significant that they occupy the same 
relative position as our yellow and gray loesses, the gray being 
the lower, and evidently the older. Indeed, the resemblance of 
these two loesses to our own is very striking throughout. 
In the following table of mollusks the columns are numbered 
as follows: 
1. Shells from the sandy part of the exposure shown in fig- 
ure 1 at c. 
2. Shells from the upper fine silt near c. 
3. Shells from the first cut at the Peczel end of the series. 
These are from yellow loess. 
4. Shells from the yellow loess of the cut south of the one 
shown in Plate XXXI, figure 1. 
5. Shells from the lower gray loess in the same cut. 
6. Modern habitats of the species.
