 that are undoubtedly connected with a violent form of fever in natives 

 which is usually fatal, and which was noticed some time ago by 

 Dr. Hodges. 



The tick was identified by Mr. Pocock as Ornithodoros monbata, 

 Murray.* 



Its connection with the fever has also been noticed by Dr. Christy.

Biting Horse Flies in Central Africa. 



Some biting Diptera \\'liich were great pests to horses wave 

 brought to the Museum by Lieut.-Col. Griffiths, D.S.(_)., Chief Veter- 

 inary Officer of the Sudau. Two of these flies mi'i-o identified as 

 (i) Glosdna iiiordtaiis, the Tsetse Fly, and (ii) the Serut Fly, 

 Tahanv.s dorsovittus, Walker. The third species was much damaged, 

 but was evidently a Stoinoxi/s. The Tsetse Flies were taken on the 

 Fongo Kiver, the Tahanus at Fashoda, and also the Stoiiioxjjs. The 

 biting Diptera are a cause of great annoyance and loss amongst 

 transport animals in tlie Sudan, especially attacking the animals 

 around the eyes and nostiils, often making transport impossible. 



Sponging the animals with paraffin not having met with success, 

 a further experiment is being carried out. 



Several drivers in the Bernese (Jberland told me bruised walnut 

 leaves rubbed over the horses kejit the flies from biting, including 

 the large Gad Flies. In one or two cases observed this certainly 

 seemed to be the case. At Colonel Griffiths' request, I offered to 

 send five sacks of walnut leaves for him to take back to the Sudan 

 M'ith him. 



The leaves, owing to incessant rains, were so moist that they
