Anatolia, however, when rearing larvae and nymphs from tick-infested 

 animals, it was found that these stages commonly attack tortoises, 

 lizards (Agama ) , partridges, man, hares, hedgehogs, and a wide 

 variety of rodents (Hoogstraal, ms.). A ninnber of Russian host 

 records were presented by Olenev (1928B). 



The life cycle of "H. aegyptium " described by Nuttall (1915) 

 applies to H. marginatum T Nuttall ' s lot 1305a in British Museum 

 (Natviral Hi'storyJ was used for this study. No material for his 

 lot X (from Rome) can now be located. It appears that the study 

 of the external morphology of each stage and of the bionomics of 

 "H. aegyptiumf * in India (Sharif 192^) applies actually to H. 

 excavat\m , but this is not certain. 



A popular article concerning the actual H. aegyptium has 

 recently appeared in the Illustrated London iJews (Browning 1950) . 

 Based on living ticks arriving in the British Isles on pet-shop 

 tortoises from southern Europe, this accoimt should interest 

 persons who frequently encovmter this name promiscuously used 

 in the literature. Distribution data in the Browning paper are 

 from literature references imder H. aegyptium , and, therefore, 

 far more extensive than the actual geographic range of this 

 species in nature. 



Contemporary published reports on disease transmission by 

 ticks'lmfortunately continue to perp'eliuate the early confusion 

 in identification of species in Ihis genus . The tortoise para. 

 "site, H. aegyptium , has neverTeen incriminated _as a vector or 

 reservoir of pathogenic organisms of man, other mammals, or 

 birds . 



H. aegyptium does, however, transmit two sporozoa to land 

 tortoises in northwestern Africa and in the Near East. These 

 are Haemogragarina ma\n:itanica and H. stepanovi (cf . Sergent 

 and Sergent I9O/V, Laveran and N8gre'~1905, Nicolle and Gomte 

 1905, Laveran and Pettit 1910, Brumpt 1933C; and Laveran 1901, 

 Marzinowsky 1927, Popovici-Baznosano 1901,1906,1907, and 

 Reichenow 1910) . Another parasite from this tick Coelomoplasma 

 hyalommae , has been briefly described by Brumpt (193SD; without 

 further classification as to group (see also Brun^at 1938E) . 

 Further stvidies on these parasites have not been encovmtered .
