Note to Terms and Signs. 



Ventral cornua is a new term whereby we describe processes protruding from 

 the postero- lateral angles of the ventral surface of the basis capituli. So far we 

 have only observed them in H. leporis-palv^tris (all stages ; see Figs. 325, 326, 328, 

 329), and in H. cinnabarina (o and L ; see Figs. 319, 320), as well as in its var. 

 punctata (o and L, Fig. 324). 



Spiracle. The letters A and D, in connection with the figures of the spiracle, 

 indicate its orientation with regard to the body of the tick : A = anterior, 

 D = dorsal. 



The explanation of the other terms and signs will be found in Part II.
