duced in the nursery of Mr. Clir. Lorenz in 

 Erfurt, and are now for sale, the seeds being 

 guaranteed to yield a large proportion of 

 peloric individuals. The peloric form in this 

 case appeared at once, but was not isolated, and 

 was left free to visiting insects, which of course 

 crossed it with the surrounding varieties. 

 Without doubt the existence of two color-varie- 

 ties of the peloric type, one of a very dark red, 

 indicating the ^^ Black prince " variety as the 

 pollen-parent, and the other with a white tube 

 of the corolla, recalling the form known as 

 '^ Delila," is due to these crossings. I had last 

 year (1903) a large lot of plants, partly normal 

 and partly peloric, but evidently of hybrid 

 origin, from seeds from this nursery, showing 

 moreover all intermediate steps between nearly 

 wholly peloric individuals and apparently nor- 

 mal ones. I have saved the seeds of the iso- 

 lated types and before seeing the flowers of 

 their offspring, nothing can be said about the 

 purity and constancy of the type, when freed 

 from hybrid admixtures. The peloric snap- 

 dragon has ^Ye small unequal spurs at the base 

 of its long tube, and in this respect agrees with 

 the peloric toad-flax. 



Other pelories are terminal and quite regular, 

 and occur in some species of Linaria, where I 

 observed them in Linaria dalmatica. The
