The free inner margins of the coxal plates (Text-fig. -ja) are produced into membranous extensions; the posterior margins of the first three pairs of plates form large lobes which overlie the plates immediately behind. The extensions of the inner margins are narrow and curved upwards and overlap one another, alternately left over right, and right over left; in the text- figure the plates are slightly pulled apart in the mid-ventral line. The inner edges of the main part of the plates bear microscopic projections, while those of the last two pairs, in addition, are fringed with setae, the whole forming an interlocking device. Thus, a firm ventral wall to the pouch is formed from the distal ends of the coxal (brood) plates. The area of the ventral integument primarily involved in the formation of the rest of the pouch is limited to the region between the free portions of the coxal plates; it extends from just in front of the first pair of plates to the posterior border of the fourth pair. It has beco
