liquefaction of gelatin but in other respects closely resembles 

 the other three strains. 



New species. — Strain CXV : This strain appears to be dif- 

 ferent from any of the others studied. A feeble trace of fluor- 

 escence was thought to have been present at times in agar cul- 

 tures. Repeated staining for flagella has shown that the latter 

 are peritrichiate. Another peculiarity about this organism i- 

 the parallel grouping of single or double cells common in cap- 

 sule and flagella preparations, c. f. Plate X, figures 3 and 4. As 

 previously noted several cells commonly occurred side by side in 

 the same capsule with several flagella arising about the periphery 

 of the latter. A careful consideration of the character of tlii- 

 bacillus seems to justify the conclusion that it is a distinct specie--. 

 The name Bacillus parallelus is proposed for this organism. For 

 purposes of reference the differential characters of tlii- new 

 species are summarized as follows:
