ENTEROIDES 



941 



by Alexander in 1914 in the supplement to the Annual Report of 

 the Local Government Board, which may well be classified here. 

 The named species may be separated as follows : — • 



A. Indol produced : — 



I. Dulcitol fermented — Wesenbergi. 

 II. Dulcitol not fermented — Giumai. 



B. Indol not produced — Fermentosus. 



Genus Enteroides Castellani and Chalmers, 1918. 



Definition.— Ebertheae which ferment glucose and lactose com- 

 pletely with the production of acid and gas. Milk not clotted. 



Type Species. — Enteroides entericus (Castellani, 1907). 



Remarks. — Castellani isolated two organisms from cases of enter- 

 oidea and appendicitis in Ceylon — viz., the type and E. paraentericus 

 — and later found another, E. vekanda, in the Balkans. 



Chalmers and Macdonald obtained E. khartoumensis from cases 

 of enteroidea in the Anglo-Egyptian Sudan. 



Classification. — The various species of the genus may be recog- 

 nized as follows: — 



Adonitol. 



No change. Acid and gas. 



Saccharose. Salicin. 



No gas. Gas. No change. Acid and gas. 



Entericus. Paraentericus. Vekanda. Khartoumensis. 



Genus Escherichia Castellani and Chalmers, 1918. 



Definition. — Ebertheae which ferment glucose and lactose com- 

 pletely ; milk clotted. 



Type Species. — Escherichia coli (Escherich, 1886). 



Classification. — The number of species gathered together under 

 this genus, even after the rejection of those so imperfectly described 

 that they cannot be classified, is so large that they require to be 

 divided into groups and sections as follows: — 



A. Indol produced — Smith's indol division. 



I. Saccharolytic — Communior section. 

 II. Non-saccharolytic — Communis section. 



B. Indol not produced— 5mi/^'s non-indol division. 



We recognize the mistake which has been made with regard 

 to the organism called Coscoroba, which, as originally described, 

 belongs to the genus Pasteur ella — i.e., among the hsemorrhagic 

 septicaemias, being a ca.use of disease and death in swans. By some 

 mistake, years ago quite a different organism belonging to the Colon 

 group received this name. In order to prevent confusion, we pro- 

 pose to call the Colon type of Coscoroba by the name Escherichia 

 pseudocoscoroba Castellani and Chalmers, I918. The species may 

 be recognized as follows: —
