the discovery of Stein, that in the stomach of the 

 meal-worm beetle (larva of Tenebrio molitor) were 

 found embryos of a tapeworm, which there afterwards 

 became scolices, waiting until its host was eaten by 

 another animal, which might perchance prove a suit- 

 able soil for its further development. 



6. Tcenia capiensis. Under this name, Kiichen- 

 meister describes an entozoon, portions of which he 

 obtained from Dr. Rose, of the Cape of Good Hope. 

 These segments were without head or neck. " Its 

 total length must be at least 6 to 10 yards. Its seg- 

 ments are very thick, white, and fat ; in the mature 

 state, more than 1 inch in length, 3 to 5'" in breadth, 

 and extremely massive. They are distinguished by 

 having a longitudinal ridge running along the whole 

 of the mature and immature segments. 



" The genital pores are irregularly alternate ; the 

 penis so much concealed behind the thick inflated 

 margin of the genital pore, that it is hardly discover- 

 able. The uterus is formed by a thick, median stem, 

 into which 40 to 60 lateral branches open: these 

 resemble those of Taenia mediocanellata, or perhaps 

 still more those of T. ex cysticerco tenuicolli, espe- 

 cially when we consider the arrangement of the 

 branches, like the teeth of a rake, at the upper and 

 lower margins of the segments. 



" The ova are oval, rather rounded, uneven, and 

 0-030 to 0-034 mil. in breadth by 0-038 to 0-040 mil. 

 in length. They allow the six-hooked embryo, which 

 is 0*024 mil. in diameter, to shine through them dis- 

 tinctly. I never saw such remarkably developed em-
