In the next place, the creature began to decline : and in sixteen 

 months from the tii^t, its length contracted to three inches and a halt

Though occasionally reviving, it never recovered its proper si/x- ami 

 vigour : and at last asMuminir the resemblance of a worm half a foot 

 long, and under half an inch thick, it died in nineteen months from 

 the date of its original acquisition. 



The skin proved extremely tough and coriaceous ; and -\eral 

 small ropes of an immature ovarium were found in the IMM|\ on dit- 

 aection. 



For some time I was disposed to view this animal as an overgrown 

 specimen of the Il<ilthnria fiuiu, especially before the parts were nifli- 

 ciently developed. But between the two, we find several prominent 

 distinctions. First, the disparity of size and proportions ; next, in lon- 

 gitudinal double rows of suckers down the Uidy. whereas those of the 

 funu are distri huted promiscuously over the whole surface, and thence 

 much more numerous, comparatively. The difference in the proportion* 

 i'-h, would render the tlevures seen in the one impracticable liy the 

 other.
