Introduction to ^[niinal Morphology. 49 



This sub-kingdom includes eight classes, which 

 form two diverging series.* 



CLASS i. MOXERA (Hacckcl}. The simplest living 

 beings ; organless, aquatic cytodes with pseudopodia ; 

 rounded when resting or starved, irregular otherwise ; 

 reproduction asexual. 



There are two orders of these : ist. Gymnomoncra, with 

 no resting stage nor capsule, reproducing by fission. They 

 may be single, non-vaeuolated with simple (Protamoc-ba,f 



i, A) or branched pseudo- Fig r 



podia (ProtogenesJ), or united 

 in clusters by netted processes 



( Myxodictyon), or in vacuolated *- 



masses with irregular pseudo- ^fi^^^ 

 podia, found at great depths in 

 the Atlantic Ocean(Bathybius). 

 2nd. Lepomonera, with a rest- 

 in- stage in which the body M;igosph;LT;l p i anula . 

 becomes surrounded by a cap- i>rimitua. 



. and the interior breaks up into flagellate spores, which 



-ion become like the parent. This includes Proto- 

 monas, a non-vacuolated form found in decaying Nitella 



i'rotomyxa, marine, in its resting stage a round orange 

 ball, whose contents break up into tailed spores, becoming 

 vaeuolated amreboid cytodes with branched pseudopodia ; 

 two or three of these coalesce to form a mass like the parent. || 

 Vampyrella is non-vacaolated, an<l reproduces by lelraplasts, 

 round masses at first dividing into two, then into four, i 



i of these becomes rounded with radiating pr- 

 they are para-itie on Al.L r ;e 'lhve freshwater and one marine
