germinal epithelium is at the anterior end just as in the typical 
case. Grassi (gg) describes and figures the ovary of Lepisma 
as consisting of five tubules arranged on the same plan as in 
Machilis and Japyx, differing in being distinctly metameric in 
the young individual but not in the adult. Petrobtus maritimus

is described by Lubbock (61) as having seven short ovarian 
tubes on each side of the abdomen; these tubes lie adove the 
intestine. 
Passing to Fig. VII, where the conditions found in Anurida 
‘are somewhat diagrammatically represented, there is evidently 
a great divergence shown from the types already studied. It 
cannot be directly harmonized with any, agreeing as little with 
Campodea as any other. The presence of two cephalic elonga- 
tions is the chief point of resemblance. These, however, are 
not connected in any direct way with the germinal epithelium; 
they are apparently thin continuations of the ovarian wall. 
Anurida, then, stands quite distinct in structure of the female
