tinge (M. roseo-persicus) ; and one (M. fragilis Dyar) is “brown 
red on glycerine agar.” These colors are not likely to be mis- 
taken, and cut the list down to those which are either “rose”’ or 
“flesh red.” Three of these (1) IZ. roseus Fliigge, (2) M. roseus 
Eisenberg, and (3) MW. voseus Maggiora are sometimes confused 
because of the similarity of name. 
(1) M.roseus Fliigge is only briefly mentioned by Fliigge him- 
self,’ but is described more at length by Macé® as a form com- 
mon in air, non-liquefying on a gelatine plate, slowly liquefying 
ina stab culture. But he says that the liquid portion is tinted 
red “more vermilion than by prodigiosus.”” Macé also mentions 
among species closely related to this, MZ. agilis Ali-Cohen, M. 
rouge cerise of List, isolated from water and producing a cerise 
color on potato, and Zimmerman’s M. carneus which Mace, a 
well as Lustig, regards as identical with Maschek’s Coccus ruber. 
He describes these as all non- motile cocci, about 0.8 in diameter, 
“rose red or flesh colored,”’ and abundant on potato. 
(2) M. roseus Eisenberg,’ to which Migula gives the name of 
M. subroseus, is found in sputum and produces a pigment like 
that of B. prodigiosus on potato. 
(3) M.roseus Maggiora is described by Ward ® asa non-lique- 
fying form 0.6 in diameter, associated in irregular glomeruli, and 
forming a pale rose pigment. I was unable to gain access ws 
further description of this micrococcus. 
As to the remainder of Migula’s list there is left: 
(4) M. cumulatus Kern, a too definitely liquefying for 
identified with the salmon-pink micrococcus. Otherwise, excePt 
ing the fact that it is a facultative anaerobe, the descriptions a 
somewhat similar. ae
