author describes his observations of numerous cases in bovines, equines 

 and camels. 



From the first, great morphological differences were visible between 

 the trypanosome in bo\-ines and that in equines. The bovine trypano- 

 some belongs to the group including Trypanosoma dimorphon, 

 T. congolcnse, T. nanum and T. pccormn. Unlike T. nammi it can 

 be inoculated into small manmials, and it is probably identical with 

 one of the three others. The cattle contract the disease on the banks 

 of the Webi Shebeli and Juba rivers and in the adjacent lands covered 

 with thick bush, where Glossina pallidipes occurs. The natives apply 

 the name " ghindi " to this fly and to the trypanosome or trypanosomes 

 conveyed by it. 



The trypanosome observed in equines has a marked dimorphism 

 that brings it into the brucei-pecaudi group ; it is not certain whether 

 it is T. brucei or T. pecaudi, or a variety of one of these. 



T. somalilense and T. cellii, described by Martoglio in 1911 as 

 the respective agents of " ghincU " and " gobiat," do not exist. Each 

 of these is a plural species resulting from a mixture of the two trypano- 

 somes described here, with perhaps the further admixture of a third, 

 such as a pathogenic species quite recently observed in cattle by the 

 author, who refers it to the type of T. cazalhoiii.

Microscopical examination of the blood of a calf, taken from the 

 cheek, showed the presence of spores of Sarcocystis, although previous 

 and subsequent weekly examinations of blood from the same region 

 proved negative. The observations here described show that it is 

 possible for insects such as Tabanids or Stomoxys to ingest large 

 numbers of these spores at one feed. The spores are dimorphic, 

 some having the characters and elements of males and others those 

 of females. This supports the theory of previous authors that insects 

 may prove to be alternative hosts of this organism.

A Leptomonas and another leishmaniform organism have been 

 isolated from the blood of Cifnex pipistrclli, Jenyns, taken from 

 bats in the department of Oran. It remains to be seen whether 

 these organisms and the trypanosomes of bats in Algeria are allied. 

 Attention is drawn to the recent discovery of Schizotrypannm in bats 

 in Alsace [R.A.E., B, ix, 120].

The presence of Hypoderma lineatum (warble-fly) on cows in the 

 Island of Kanai is recorded. These animals had been imported from 

 the mainland some few months previously, and were doubtless infested 

 before they were shipped. Although the same thing has probably 

 occurred before, the fly does not seem to have become established
