SUMMARY OF CURRENT RESEARCHES RELATING TO 



and a posterior homogeneous zone. The latter represents a large food 

 vacuole containing a siderophilous body. There seems to be no binary 

 fission, only an internal division into four pseudocysts. During the 

 division the monad has no flagellum, and its shape is globular. It is 

 probable that this new form is one of the Protomonadinge, not far from 

 Ancyromonas sigmo'ides. Perhaps it is the same as Bodo celer described 

 by Klebs. According to Alexeieff, AJphamonas is of particular interest, 

 inasmuch as it links Bacteria and Flagella. It suggests Bacteria in its 

 stiff curved shape, its very delicate flagella, and the formation of spores 

 with epiplasm. J. A. T.

 Malpighian tubules, It is linear in shape, with an elongated-nucleus. 

 Its neuromotor apparatus consists of centrosome, blepharoplast, four 

 myonemes, and six flagella connected with the nucleus by the rhizoplast. 

 Binary fission apparently occurs without spindle formation. The nucleus
