blindly ending capillaries described by the former author , instead of 

 ending blindly , as he thought, divide again in threes, each one of 

 which latter branches is terminated by a »Trichter«. The capillaries 

 are without cilia. The ciliary cone of the funnel is shorter and , rela- 

 tively to its length . broader than that of the vessels and at its base is 

 a nucleated funnel-cell. The whole funnel-organ is so far characte- 

 ristic that when one has educated his eye to it one can find them quite 

 easily and can at once distinguish the »Flimmerung« of a »Trichter« 

 from that of the conducting vessels. I will only state further in this 

 connection that in the embryo before it leaves the shell there are at 

 least two pairs of funnels present — immediately behind the anterior 

 and in front of the posterior suckers — and that in the adult there are 

 two pori excretorii. 



Regarding the genital organs I find that the »dreieckiger Raum« 

 is not the ootype. Its cilia extend from the opening of the unpaired 

 vitelline duct to the tuba and act in this direction. The receptaculum 

 vitelli with its duct are the Laurer's canal. Pursuing the oviduct 

 outwards , at a distance from the opening of the vitelline duct equal 

 to that of the latter from the Laurer's canal , one finds the shell- 

 gland with its radiating ducts, and immediately succeeding it a widen- 

 ing in the oviduct with thickened walls, the ootype. Beyond this is 

 generally a contracted portion with again an expansion filled to di- 

 stention, in the sexually adult animal, with sperm-cells. The latter is 

 the part designated by Loos s »Receptaculum seminis uterinum«. 

 These organs have been hitherto overlooked. 



The penis is a highly complex organ and decoyed Voeltzkow 

 into numerous errors. Between the »Penisschlauch« and the ductus 

 ejaculatorius is no epithelium and no space filled with a watery fluid 

 but a continuous parenchym. The bulbus is , at least as to its essen- 

 tial structure, a large papilla-like forward growth into the greatly 

 widened ductus from the posterior end of the »Penisschlauch« 

 through the centre of which passes the continuation of the vesicula 

 seminalis opening at the anterior tip of the bulbus. The walls of 

 the ductus are posteriorly incorporated into the bulbus structure but 

 along its outer surface are a number of longitudinal infoldings 

 where the ducts from the prostate gland grow inwards carrying 

 with them the parenchym. These infoldings meet with the outer 

 walls of the forwardly projecting papilla and coalesce with it forming 

 the septa figured, but incorrectly, by Voeltzkow. At the broadest 

 part of the bulbus there are about a dozen septa between which are 

 somewhat wide canals, the latter receiving the ends of the prostate 

 ducts. More anteriorly the septa fail and the intervening canals fuse
