This trypanosome is found also in domestic cattle, 

 dogs, pigs, and rarely also in sheep and goats. 



Symptoms. (i) Weakness. (2) Intermittent fever. 



(3) Oedema of testes, but not elsewhere, as in Ngana. 



(4) Paraplegia. The disease lasts many months, or 

 over a year, and recovery may occur. 



Blood Examination. Parasites may be scanty at 

 first and more numerous when the febrile attacks are 

 well marked. Later they again become rare, but may 

 be abundant before death. 



Morphology. Three forms occur : (i) Tadpole 

 form in the early stage of the disease, 11-13^ by 

 o* 1 8-1 /^. (2) Long forms, 26-30^ by r6-2/* a few days 

 before death. (3) Stumpy forms, 16-19/4 by 3*4-3*5^. 



According to Liihe, No. (i) represent an indif- 

 ferent; No. (2) amale(?); No. (3) a female trypanosome. 



Transmission. Gl. palpalis is capable of trans- 

 mitting infection. 



8. T. cazalboui (Laveran, 1906). The cause of 

 Souma, a fatal disease of ruminants in French Soudan. 



Symptoms. Oedema, paresis, and cutaneous erup- 

 tions urticarial in character. It is non-infective for 

 monkeys, dogs, and rodents, but goats and sheep are 

 readily infected. 



Transmission is by Stomoxys bouffardi. 



9. T. soudanense. The cause of a disease of 

 dromedaries in Sudan, probably a variety of Surra. 

 The pathogenic action on mice is similar to that of 

 the trypanosomes of El Debab and Zousfana. 



10. T. pecaudi. The cause of Baleri, a disease of 

 equines in French Soudan. The symptoms are (a) 

 repeated febrile attacks, (b) eye symptoms, (r) skin 

 eruptions and plaques, resembling those of Dourine, 

 (d) oedema of genitals. Two forms occur (i) 25-35 

 by 1*5/4, (2) 14-20 by 3-4^. It resembles T. dimorphum.
