SPOBOZOA. 



elongated and subconical, with its apex somewhat cup-shaped, 

 marked with distinct epicytal striations. Protomerite not 

 more densely granular than the deutomerite, broadest at its 

 base, width usually greater than its length, showing a somewhat 

 obliquely running furrow. Protomerite, together with the 

 epimerite, bent at an angle on the deutomerite. Deutomerite 

 widest anteriorly, and narrower and rounded posteriorly, 

 its maximum width may be somewhat greater than the length ; 

 marked by two incomplete septa running inwards from one 

 side. Length of the protomerite to total length as 1 : 3*8, 

 width of the protomerite to width of the deutomerite as 

 1 : 1-3. Nucleus large, oval, situated near the posterior end, 

 containing a single large, spherical, eccentrically placed karyo- 

 some, surrounded by a narrow clear area and densely packed

chromatin granules. Sporont solitary, proportionately 

 narrower and much more elongated than the cephalont ; 

 may be bent upon itself, and the deutomerite may show 

 incomplete septa. Nucleus in the sporont may be oval or 

 spherical, but is similar in structure to that in the cephalont. 

 Cyst- and spore-formation not known. 



Dimensions. — Cephalont up to 402-5 ju, in total length 

 epimerite 105 ju, in length and 17 [x in maximum width 

 protomerite 105 /x in length and 147 /^ in maximum Avidth 

 deutomerite 192-5 /x in length and 203 /x in maximum width, 

 nucleus 52-5 /u by 45-5 /x. Sporont up to 420 /x in total length 

 and 105jLi in maximum width, nucleus 42 /x in diameter. 



Remarks. — The furrow on the protomerite and the incom- 

 plete septa and a furrow in the deutomerite strongly recall
