150 TRANSACTIONS OF THE [APR. 18, 
marked “ Staphylococcus pyogenes citreus,’ was found in the col- 
lection. It was the same in all respects, but the growth was soft 
and not wrinkly. Cells in pairs and fours, but often slightly 
elongated. 
My reason for rejecting the determination of these cultures 
and applying a new name was that Staphylococcus pyogenes ci- 
treus is described as the same on all media as Staph. pyog. au- 
reus, which is not the case here. However, if ‘‘all media” refers 
only to gelatin, agar and potato, my construction of the descrip- 
tion may have been too rigid and the cultures may be correctly 
named. I do not otherwise know S. pyogenes citreus. 
36. BACILLUS SARRACENICOLUS. 
31. BACILLUS VACUOLATUS. 
The cultures are dead. 
39. BACILLUS SUBOCHRACEUS. 
The characters are unchanged except that milk is more quickly 
coagulated (9 days), but only on boiling even in 26 days. Ni- 
trate is very decidedly more strongly reduced yet not completely. 
The species is a facultative anaerob. 
40. BACILLUS DOMESTICUS. 
This species now liquefies gelatin. The liquefaction begins 
after about 34 days and proceeds slowly. In 50 days about 
one-fourth of the medium in the tube was liquefied. 
There is also a pink tint in the liquefied part. Nitrate is 
less strongly reduced, not completely in 30 days. Milk is not 
coagulated at first, but in 31 days a coagulum was obtained on 
boiling. Lactose-litmus agar is reddened as before and the yel- 
low color is retained, otherwise the species is scarcely recogniz- 
able. The cells are shorter than before, sometimes scarcely dis- 
tinguishable from Micrococci, The species is aerobic. 
44, BACILLUS JAVANIENSIS. 
The nitrate was not reduced at all, otherwise the characters 
remain the same. 
54. BACILLUS FUSCUS PALLIDIOR. 
55. BACILLUS FERRUGINEUS. 
56. BAcILLUS SALMONEUS. 
57. BACILLUS FINITIMUS RUBER. 
The characters are unchanged.
