Adaptatio7i of TicliS 
Of the other species of Argasidae which have been enumerated in 
the list on pp. 48, 49, too little is known to permit of much comment. 
It would seem to me as if A. hrumpti, 0. turicata and 0. pavimentosus 
may prove, on investigation, to have a life-history similar to that of 
0. moubata and 0. savigmji ; 0. talaje and 0. tholozani may possess 
life-histories like A. 2ys7-sicus, and this appears highly probable for 
0. talaje var. capensis. It is to be hoped that the life-history of 
0. lahorensis will be worked out in India. We are studying 0. turicata 
and 0. talaje var. capensis. 
Note on the structure of the Hypostonies in Argasidae. 
The dentition of the hypostome is in accord with what I have 
stated regarding the feeding habits of the Argasidae. This is illus¬ 
trated by typical examples in the accompanying figures. Thus, in 
A. persicus, reflexus and vespertilioyiis, where the larvae attach them¬ 
selves to the host for some days, or longer, the larval hypostome is
