Of the other species of Argasidae which have been enumerated in 

 the list on pp. 326, 327, too little is known to permit of much comment. 

 It would seem to me as if A. brumpti, 0. turicata and 0. pavimentosus 

 may prove, on investigation, to have a life-history similar to that of 

 0. movhata and 0. savignyi; 0. talaje and 0. tholozani may possess 

 life-histories like A. persicus, 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 Hypostoines 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 vespertilionis, where the larvae attach them- 

 selves to the host for some days, or longer, the larval hypostome is
