In segments which have been expelled separately, we have ob- served the ovary to be nearly empty; and it is in these that the male duct and gland are most easily perceived.

WORMS. 479 in the ovary, and in those situated on the posterior segments of the body they generally present a brownish colour, which renders the form of their receptacle sufficiently conspicuous. In segments which have been expelled separately, we have ob- served the ovary to be nearly empty; and it is in these that the male duct and gland are most easily perceived. For this purpose, it is only necessary to place the segment between two slips of glass, and view it by means of a simple lens magnifying from 20 to 30 diameters. A well-defined bine (</), more slender and opaque than the ' oviduct, may then be traced, extend- ing from the termination of the ovi- duct, at the lateral opening, to the middle of the joint, and inclined in a curved or slightly wavy line to near the middle of the posterior margin of the segment, where it terminates in a small oval vesicle. This, as seen by transmitted light, is subtransparent in the centre, and opaque at the circum- ference, indicating its hollow or vesi- cular structure. The duct, or vas de- ferens, contains a grumous secretion; it is slightly dilated just before its termination. In this species, there- fore, the ova are impregnated on their passage ;—(Cyclopaedia of Anatomy, art.
