In a previous paper (Eggerth and Gagnon, 1933) the predomi-nance of non-spore-bearing anaerobic bacilli in human feces was reported, and a number of the Gram-negative species were de-scribed. As observations on the Gram-positive species were at that time incomplete, they were omitted. Bergey's Manual of Determinative Bacteriology (1934) defines the genus Bacteroides as consisting of "motile or non-motile rods without endospores. Show good growth with ordinary culture media; without pigment formation. Obligate anaerobes. " If this definition is accepted, the Gram-positive species described in this paper fall into the genus Bacteroides. For reasons that will appear later, the writer believes that the Gram-negative Bacte-roides and the Gram-positive non-spore-bearing anaerobic bacilli of the intestine are biologically quite distinct and should be placed in different genera at least; possibly in different tribes or even in different orders. For the present, however, the nomen-clature of Bergey's Manual will be followed, as the Manual is the only authoritative system of classification we have. The Gram-positive species will be designated as Bacteroides, though it is certain that they will ultimately be placed in another genus. The organisms to be described were obtained from plate cul-tures of 85 stools: 11 of these were from breast-fed infants; the remainder, from normal adults. All of them were strictly anaerobic when isolated; with the exception of certain strains of Bacteroide...
