Crawley (H.). Note on the stage of Piroplasma higeminum which 

 occurs in the cattle-tick, Margaropus annulaius. — Jl. of Parasito- 

 Icgy, Urbana, III, ii, no. 2, December 1915, pp. 87-92, 1 fig. 



A parasitic protozoan, found in smears made from female cattle- 

 ticks {Margawpus annulatus) and from crushed eggs, is believed to 

 represent the stage of Piroplasma higeminum occurring in the tick. 

 In the present case, the unusual mortality of the ticks would suggest 

 that the parasite is pathogenic to them as well as to cattle.

 they convey .^J5wZ/. Entom. Research, London, vi, no. 4, February 

 1916, pp. 313-352, 48 figs. 



The subject of ticks and tick-borne diseases is of great importance 

 to agriculturists and pathologists in the Belgian Congo. Of the species 

 recorded from the Congo, one conveys relapsing fever to man and 

 eight have been shown to carry diseases to domestic animals in various 

 parts of Africa. After giving a brief summary of the classification of 

 the group, the general characters of the different genera, and the biology 

 of ticks, the author gives a more detailed account of the species found 

 in the Belgian Congo, and their relation to disease. The species 

 recorded include Ornithodorus mouhaia. Murray, conveying relapsing 

 fever to man in many parts of tropical Africa ; Haemaphysalis leachi, 

 Aud., carrying canine piroplasmosis ; Rhipicephaliis appendiculatus, 

 Neum., transmitting African Coast Fever in cattle ; R. capensis, Koch, 

 found experimentally to carry African Coast Fever ; R. evertsi, Neum., 

 carrying equine piroplasmosis ; R. sanguineus, Lat., a carrier of 

 canine piroplasmosis in India and probably also in Africa ; R. simus, 

 occasionally carrying Rhodesian fever in cattle ; Margaropus 

 (Boophilus) decoloratus, Koch, conveying bovine piroplasmosis 

 throughout tropical and southern Africa ; Hyalomma aegyptium, 

 probably a transmitter of Nuttallia equi, causing biliary fever in horses ; 

 and Amblyomma hebraeum, Koch, carrying " heartwater," a frequently 

 fatal disease in sheep, goats and cattle. The best methods of collecting, 

 preserving and breeding ticks in captivity are described. An index to 

 Congo ticks and their hosts is appended.
