The eggs of the mollusc Lymnaea stagnalis generate weak extracellular ionic currents, which have been mapped from oviposition through first cleavage. Throughout this period the current is inward in the animal hemisphere, with highest density at the a

As in many other stingless bees, Melipona bicolor bicolor Lepeletier (Apidae: Meliponinae) workers lay two morphologically distinct types of eggs: slender ones that have a typical patterned chorion, and larger ones that lack this pattern. In this pap

To study the reproductive potential of workers in the stingless bee Trigona (Tetragonisca) angustula Illiger (Apidae, Meliponinae), we examined the morphological quality of their eggs. Worker-eggs were all placed on the inside of the upper wall of br

In the first polar lobe ofBithynia eggs a special plasm, the vegetal body, is present. It consists of a cupshaped aggregate of small vesicles. Centrifugation of eggs prior to first cleavage may result in displacement of the vegetal body. In about 50%

Some novel structural features of the polar lobe of the egg of Crepidula are described. The significance of two kinds of aggregate is discussed in relation to the morphogenetic factors present in polar lobes generally. Surface configurations of the p

In the first polar lobe of the egg of Bithynia tentaculata a cup-shaped mass of small vesicles is described, which fills the greater part of the lobe. It is named the ‘vegetal body’. With methyl green-pyronin the vegetal body stains clearly, but

Summary In late previtellogenic oocytes nuage material accumulates in the vicinity of the nucleus and is often seen to be intimately associated with cisternae of endoplasmic reticulum (ER). A similar association observed in Ilyanassa has given rise t
