9 2 Sakni.- — On an Australian Specimen of Clepsydropsis . 
Fig. 3. Longitudinal section of the same, x c. 43. 
Fig. 4. Longitudinal section of a portion of a petiolar strand, to show the finely scalariform 
pitting 01 the tracheides. x c. 133. 
Fig. 5. Transverse section of a portion of the petiolar strand, also shown in Text-fig. 2, j. 
Owing to a fracture in the xylem, the peripheral loop appears considerably wider than is normally 
the case ( compare with the undisturbed strand shown in Text-fig. 2). The loop is lined internally 
as well as externally by specially narrow tracheides. x c. 40. 
Fig. 6. Transverse section of the petiolar strand, also shown in Text-fig. 2, 9. a., a., antennae; 
peripheral loops; s.t., small tracheides, forming a more or less complete bridge between the two 
loops, x c. 29. 
Fig. 7. Longitudinal section of the same strand, passing radially across its median plate, to 
show the small tracheides, s.t., flanked by the larger tracheides. x c. 33.
