The adult condition has now been reached. This has been fully described by D. D. John (1936) in his paper on " The southern species of the genus Euphatisia ", and he has kindly allowed me to quote his description and to reproduce one of his figures. When the mature petasma is unrolled (Figs. 16 a and b) it can be seen that the "proximal part of the terminal process pt is bent nearly at a right angle to the distal part, which is about three times as .The end of the process tapers and curls forwards; it is not bifid. The distal two-fifths of the proximal process/"/) is bent inwards.
