There is nothing in the female corresponding to the supra-intestinal vesiculaeseminales of the male.
The atrium receives the secretion of two pairs of large accessory glands; and a pair of tubes, or vesiculae seminales, open, one on each side, into the divided sperm ducts close to their point of origin above the intestine.
The right and left portions of the intestinal ring of the genital duct are unequally developed, and there are no vesiculae seminales, but two pairs of accessory glands communicate with the genital atrium as in Lithobius.
At this age there is no trace of the vesiculae seminales, so conspicuous in the mature Cirripede.
The vesiculae seminales are much convoluted and of great length.
The inner tunic is prolonged up the probosciformed penis, at the base of which the two vesiculae unite.
The vesiculae seminales are large; and at their broad blunt ends, in C.
With respect to the generative system, I have only to remark, that the vesiculae seminales are of great length, and convoluted to a remarkable degree.
The specimens as yet described are exclusively female, there being certainly no testes or vesiculae seminales.
The vesiculae seminales in this same species are large, with their broad, blunt ends reflexed.
The animal we have thus far described is exclusively female: when a longitudinal section of the thorax is made, and the stomach removed, it can be most plainly seen that there are no vesiculae seminales or testes.
The vesiculae seminales occupy their usual position in the prosoma; they are not much convoluted; they unite before entering the penis.
The contents of the vesiculae are commonly pulpy and cellular; and from the cells the spermatozoa are developed; soon after their development, they are, as it appears, expelled.
The testes andvesiculae seminales have to be formed.
Testes large, branched like a stag's horns, attached in a sheet to the ventral surface of the stomach: the vesiculae seminales enter the prosoma, and have their reflexed ends not very blunt.
In one specimen, I believe I distinguished the vesiculae seminales: if so, they contained only pulpy matter, and not spermatozoa.
In the one specimen preserved in spirits, I unfortunately omitted to search for the vesiculae seminales; I cannot doubt that such existed, but it would have been important to have ascertained whether they contained spermatozoa.
It should be borne in mind, that in some of the specimens there were perfect spermatozoa in the vesiculae seminales (as likewise in some of the males of I.
The testes are large, but the vesiculae seminales in some of the species extraordinarily small.
The testes run into all the filamentary appendages, as well as more or less, into the pedicels of the cirri: the two vesiculae seminales unite within the penis, either just beyond its basal constriction, or up one third of its length.
The ova are impregnated (as I infer from the state of the vesiculae seminales), when first brought into the sack, and whilst the membrane of the lamellae is very tender: the long probosciformed penis seems well adapted for this end.
The vesiculae seminales unite and terminate under the two extremely minute caudal appendages, and here I think I saw an orifice; but there is certainly no projecting, probosciformed penis.
Vesiculae seminales not reflexed at their broad ends; white, spotted with black.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "vesiculae" in a variety of sentences. We hope that you will now be able to make sentences using this word.
