are only observed when a great number of embryos reach the 

 liver at once, or in rapid succession. The rabbit rapidly loses 

 flesh, becomes shrunken and weak, and its mucous membranes 

 are pale and bloodless. 



Prevention is exactly as for Cysticercus tenuiformis.

TiENIA FIMBRIATA IN THE UVBR. FRINGED TAPEWORM. 



The fringed taenia is so named because the posterior border of 

 each segment is split up into an abundant fringe, and when the 

 worm is longitudinally contracted this stands up as a sort of nap 

 giving a velvety feeling to the surface. The parasite appears to 

 be strictly American. It was discovered in 1824 by Natterer in 

 Brazilian deer, and later in several varieties (Cervus paludosus, 

 C. rufus, C. simplicornis, C. nambi and C. dicotomus). 



In 1887, Dr. Cooper Curtice definitely ascertained that the 

 great losses from tapeworm among the sheep of the Western 

 Plains, were due almost entirely to the T. Fimbriata. From evi- 

 dence collected by him, it became plain that this was further the 

 most destructive sheep entozoon of the Rocky Mountain Regions 

 and of the Pacific Coast. Mr. Stewart's parasite from Missouri 

 sheep, described by him as the Taenia Plicata, is evidently the T. 

 Fimbriata, as the former does not occur in the sheep, and the 

 latter closely resembles it in its size and in the shortness of its 

 segments. Dr. Faville had studied the parasite in Colorado, 

 showed its presence in the bile ducts, and attributed to it the 

 losses which had been usually referred to " loco " disease. 



Description of T. Fimbriata. The mature taenia is from five to 

 ten inches long by ^ inch broad. It encreases in breadth from 

 the head to about Yi inch from the caudal end, where it shows a 

 terminal narrowing. The segments are so exceedingly narrow 

 from before backward that when the para.site is contracted the 

 divisions are effaced and the surface has a velvety a-spect, but when 

 longitudinally extended the lines of segmentation appear like 

 rather coarse transverse striae. The head is large, tetragonal and 

 bears a sucking disc on each of its angles. The anterior border 

 of each segment is smooth and convex from above downward and
