CORRIGENDA IN SERIES V. 
Various errors have unfortunately occurred in the engraving of the 
plates. 
Plate II, fig. 2. The cellulation should have been regularly hexagonal. 
Eig. 3. The short marginal striae should have been only just visible. Eig. 5 
should have been shaded throughout, to represent the lurid colour. Eig. 6. 
The scattered raised points on the surface should have been exceedingly 
faint. 
Plate III, fig. 6. The punctation should have been quite pale. Eig. 7. 
The dark radiating lines should not have been represented as shadows, but 
as defined lines, passing into, and anastomosing with, the quadrate cellula- 
tion towards the margin.
