* A mode of estivation (as seen in P. violacea) to approach near Sal- 
piglossis ; its definition may perhaps be thus extended, nempe; lobis om. 
nibus medio conduplicatis, plicaturis utrinque versus superiorem torsis,

latis, unici lateralis aut interdum inferioris omnino exterioris marginibus 
imbricatis, ceterorum torsive imbricatis et vicissim obvolutis, sed duorum 
inferiorum dimidiis proximis gibboso-inflatis, inferne voluto-plicatis, 
superne autem simpliciter imbricatis: this complex mode of zstivation is 
shown in Plate 24,
