GENERAL SYSTEMATIC BACTERIOLOGY 299 



The description given for E. longa is as follows: 



Thallus long, filiform, colorless, or brownish, transparent, cylindrical, usually 

 not holding a constant relation of breadth to the length, forming a simple curve 

 or single spiral turn, and then proceeding in a straight line or gently flexuose curve 

 to the free extremity. Pedicle very short, columnar, expanded at the base. 

 Principal cell ver)' long, uniformly cylindrical. Secondary cells in various stages 

 of development from ten to thirty in number, oblong, or short cylindrical, with 

 obtusely rounded extremities when completed. 



Whole length from 2 to 7 lines. Length of pedicle go^ss to is^oo o^ ^^ inch. 

 Breadth of principal cell, from si,k^ to the si- of an inch. Length of secondary 

 cells, from the 525 to the ^i^ of an inch. 



Habitation. Parasitic, growing in profusion from the mucous membrane of the 

 posterior part of the intestinal canal of Polydesmus virginiensis. 



The generic name is probably valid, but it i« questionable whether 

 the organism belongs with the bacteria. 



Eiterbacterium. A casual designation used by Kiittner (1895, p. 

 263) for his Pyobacterium fischeri. 



Eitercoccus. A casual name used by German writers as a designa- 

 tion for pus coccus. (Rosenbach 1884, p. 23.) 



Encapsulateae. The name proposed by Castellani and Chalmers 

 (1919, p. 932) for the ninth tribe of the family Bacillaceae. The 

 description (1919, p. 934) is as follows: 



Bacillaceae growing well on ordinary laboratory media, without endospores; 

 neither fluorescent nor chromogenic aerobes, not liquefying gelatin, possessing 

 capsules in animal tissues. 



Type Genus. Encapsulatus Castellani and Chalmers, 1918. 



One genus only, Encapsulatus, is included. 



Bergey et al. (1923, p. 237) recognize Encapsulateae as the seventh 

 tribe of the family Bacteriaceae with the following description: 



Short rods, somewhat plump with rounded ends, mostly occurring singly. 

 Encapsulated. Non-motile. Gram -negative. Ferment a number of carbo- 

 hydrates with the formation of acid and gas. Encountered principally in the 

 respiratory tract of man. Aerobic, growing well on ordinary culture media. 



This probably should yield priority to Klebsielleae q.v. 

 Encapsulatus. The only genus of the tribe Encapsulateae proposed 

 by Castellani and Chahners (1919, p. 934) with the description: 



Encapsulateae with the tribal characters. 



Type Species. Encapsulatus pneumoniae (Friedlaender, 1883).
