Trypanosoma sp. (?). 



Found by Tobey in the American newt, Dienycleitus viridescens. 



Section III.: Trypanosomes of Reptilia. 



Tortoises. — -Trypanosoma damonics Laveran and Mesnil, 1902, in Damonia 

 reevesi, an Asiatic tortoise; T. vittatcB Robertson, 1907, in Emyda vittata in 

 Ceylon, the intermediate host being a leech. 



Crocodilia. — Trypanosoma grayi Novy. — This parasite, which was thought 

 to be part of the life-cycle of the Trypanosoma of the crocodile, is now known 

 to be a Crithidia, 



Lizards. — T. boueti Martin, 1907, in Mabuia raddonii ; T. leschenauUii Robert- 

 son, i<^oj,inHemidactylusleschenauUii,'m.CQY\on-, T. perfenueKohertson, 1907, 

 in Hemidactylus triedri leschenaulti, in Ceylon. 



Ophidia. — T. pythonis Robertson; Mesnil is doubtful whether this is 

 not a haemoproteus, while Sambon considers that it is a haemogregarine, 

 [H.robertsoni). T. erythrolampri Wenyon, 1909, in Erythrclampus cssculapii, 

 T. primeti Mathis et L6ger in H. piscator, T. najcB Wenyon, 1909, in 

 Naja nigricollis.

ANIMALS. 



TRIBE 3: TRYPOCASTELLANELLE^. 



This tribe may be divided into : — 



Section I. : Trypanosomes of Aves. — These are but little known, 

 and, pending further study, we must retain the old genus Trypano- 

 soma sensu lato. 



Section II.: Trypanosomes of Mammalia. — They may be 

 classified as follows: — 



Series {a). — Non-Pathogenic. 



1 . Classifiable : — 



Genus Lewisonella. 

 Genus Endotrypanum. 



2. Unclassifiable : — 



Old genus Trypanosoma sensii lato pending further work. 



Series (b). — Pathogenic. 



1. Classifiable : — 



Genus Schizotrypanum. 

 Genus Castellanella. 

 Genus Duttonella. 



2. Unclassifiable : — 



Old genus Trypanosoma sensu lato pending more research. 



3. Little known. 



The classifiable mammalian trypanosomes may be recognized by 

 the characters given in the following table : — 



A. With schizogony in the vertebrate host — Schizotrypanum 

 Chagas, 1909.
