Nuttallia equi appears to be much more widely distributed than 
Firoplasma caballi (q.v.), it produces a similar disease with haemoglo- 
binuria and jaundice, etc. in Italy, Sardinia, in many parts of Africa 
Transcaucasia, India, Southern Annam and Brazil, from all of which 
countries blood-films for examination have been sent to me by corres¬ 
pondents. 
Fig. 10. Nuttallia equi ; (1) entrance of minute oat-shaped parasite into a corpuscle ; 
(2-5) the parasite grows in size whilst continually but slowly altering its shape ; 
(6) larger parasite which is actively amoeboid; (7-10) successive stages of division of 
the chromatin; (11-15) process of division repeatedly observed in living parasites: 
the formation and breaking-up of the cross-forms, the scattering of the daughter-cells 
within the corpuscle, and their escape from the corpuscle. (Nuttall and Strickland, 
1912.)
