which project into the interior of the body, being attached by a small 

 part of their circumference ; and becoraing very wide and free near the 

 head. The dorsal and ventral nervous cords are plainly visible in 

 the midspace of the lateral vessels. The muscular tunics of the body 

 are well developed, consisting of external transverse and internal 

 longitudinal fibres. The latter are lined with a layer of pulpy floc- 

 culent substance. 



"The malė organs consist of a sHghtly-curved slender single 

 spiculum, projecting from the caudal extremity of the body, as 

 above described. The base of this spiculum communicates with a 

 dilated receptacle, 2 lines long, of an opake ■vvhite colour, which is 

 separated by a slight constriction from the ręst of the serainal tube ; 

 this is, as usual, single : it is semi-transparent, and gradually grows 

 sraaller to its blind extremity, which is attached by cellular tissue to 

 the middle line of the venlral surface of the body, half-\vay between 

 the two extremities. The ■tt'hole length of the seminal tube is ten 

 times that of the entire worm. 



" The female organs consist of the vulva, vadina, uterus hicornis, 

 and oviducts or ovarlan tiibes. 



"From the vulva, the situation of \vhich has been already men- 

 tioned, the vagina is continued, at first wide, then narrower, and lastly 

 widening again to pass into the vteriis: it exceeds an incli in length. 

 ITie tvvo cornua of the uterus are each about Į a line in diameter, and 

 5 lines in length; they diminish and are continued \vithout any con- 

 striction into the ovarian tubes ; these are of immense proportional 

 length, each exceeding, by 30 times, the length uf the body ; their at- 

 tenuated extremities or beginnings are not attached to the pa7-ieies 

 of the body ; although the coils of the oviducts appear at first sight 

 to be inextricably intervvoven around the intestine, they in reality 

 cover it in aggregate folds, Avhich are easily separated from the in- 

 testine, and unraveUed." 



Mr. Owen stated in conclusion, that preparations exhibiting the 

 malė and female organs thus unfolded, •vvith the digestive canal and 

 salivary apparatus, had been deposited in the Muscum of the Royal 

 CoUege of Surgeons.
