from the attacks of Tabanidae by means of cloths. Mr. Little- 

 wood informed the author that several years ago he saw horses 

 showing symptoms similar to those of trypanosomiasis in camels 

 which were pointed out to him by the Bedouins of Eastern 

 Sharkia as having been " struck " by the fly. Piot Bey has made 

 the same observation. The disease does not appear to be a 

 common one, and the author, after searching for nearly 4 years, 

 did not succeed in finding a case until 22nd October 1911, a 

 chestnut arab belonging to the Khedivial Agricultural Society. 

 Subsequently other cases were found in 3 police horses and 

 another chestnut arab recently imported by the Bedouins. 



Lloyd (L.). New Nematode Parasite of Glossina tnorsitans. — 

 Jl. Loud. Sch. Trov. Med. II. Pt. 1. Dec. 1912. p. 41. 



Mr. Lloyd writing from Mpika (3rd March 1912) as to a 

 nematode which he has found parasitic in Glossina viorsitans, 

 reports the finding of four specimens in " wild " flies. He 

 suggests that the worm will be of interest as throwing some light 

 on the question of the food of this tsetse-fly. There are only 

 two ways in which the parasite can obtain access to the fly. either 

 from an animal, or from water. It is a disputed point whether 

 Glossina takes up water. Dr. Kinghorn has observed G. palpalis 

 settling on the edges of puddles near Lake Tanganyika, and 

 Lloyd has seen G. ■morsitaris doing the same on the ]Vyamadzi. 

 G. morsifans will settle on wet blotting paper and thrust its 

 proboscis into it, but Lloyd has never been able to prove by the 

 use of coloured liquid that water was actually absorbed. The 

 worm has been found in two flies only, out of about 300 wild flies 

 dissected between September and March. In both cases during 

 the last two weeks. 



Dr. E. T. Leiper adds a note to the effect that the specimens 

 are all immature adult examples of a species of Mermis, and 

 resemble somewhat closely that found by Prof. Minchin a few 

 years ago in G. palpalis in Uganda.
