1 The modifications consist in the scapular patches being less pronounced and the absence of the small antero-median and lateral patches.

1 The various measurements of nymphs and larvae were made on eight specimens chosen from amongst many because of the apparent differences they exhibited in point of size. The differences were, however, very slight or nil.

1 For description of ♂, ♀ and o, and figures thereof, see Ticks, Part II, pp. 256–261. In this connection I would note that an American reviewer of Part II has criticized our descriptions of the immature stages because of their brevity. It is however obvious that lengthy descriptions are unnecessary when accurate figures form an integral part of a description and the immature tick possesses the essential characteristics of more adult forms which have been adequately described elsewhere. The literature on ticks is already overburdened with long descriptions of such a vague character that they are of no use to the systematist.
