the base of the ovipositor. The abnormal conditions in the case men- 

 tioned have prevented its even deposition and the amber-coloured, 

 chitinous (?) material is mostly collected in a large plug attached to 

 what was the inner end of the egg. I have little doubt that the wrinkl- 

 ing of this chitinous (?) membrane as it dries upon the already em- 

 bossed underlying membrane gives rise to the complete sculpture of 

 the perfect egg-shell , for the smooth papillae of the thick membrane 

 exactly correspond in arrangement with the crumpled papillae of the 

 perfect shell. 



The development of the embryo within the egg-shell appears to 

 occupy a long time , for, as I have stated in a previous paper, one of 

 the eggs laid in my vivarium in Melbourne hatched out after an in- 

 terval of a year and five months from the time of laying. 



In the male the genital papilla is situated in the same position as 

 in the female, but is much less prominent. On either side of it, in the 

 angle between the leg and the body , is a white papilla bearing the 

 aperture of an accessory gland. Behind it and just in front of the anus 

 are a pair of apertures belonging to other accessory glands. Crural 

 glands occur in all the legs from the second to the thirteenth and 

 possibly also in the fourteenth. The aperture of the crural gland is 

 situated on the under surface of the leg, and the nephridial aperture 

 lies inside it except in the fourth and fifth legs. *The white papilla 

 which bears the aperture of the crural gland may be either prominent 

 or sunk in a depression, according to the state of contraction, and 

 hence the number of these white papillae on the under surfaces of the 

 legs may appear to vary in diiferent specimens. I have been unable 

 to find any crural glands in the female.
