affixed to a stake bearing the legend "Cerions Z." These represent 

 the initital planting of Colony G. The variations presented by the 

 adult specimens are discussed in the 1915 report. 



On June 27, 1915, we found that this colony had spread materially 

 and that many of the snails had taken to the bay cedars bordering the 

 little meadow. Of the first generation of Florida-grown specimens 

 646 were gathered, 250 of which were photographed and measured. 

 For measurements see table 5, and for the photographs see plates 15-21. 

 These were marked and deposited in the north end of the meadow and 

 the place marked by a stake and a tag bearing the legend: "Cerions, 

 1915, K." These represent the initital planting of Colony K.
