11. Tcenia serrata, Goeze (Path. Mus., 31), obtained 

 several times from the small intestine of dogs used in the 

 experimental work of the laboratory, several examples, as a 

 rule., from each host. 



12. Tcmia saginata, Goeze (commonly known as Tcenia 

 mediocanellata, Kiichenmeister) : this, the ordinary "beef 

 tapeworm," from the human intestine, has been brought 

 into the laboratory at least seven or more times within the 

 past few years from this State or from New Jersey (Path. 

 Mus., 27; Path. Hist, 151, 978, 1651), although not all of 

 these are recorded. One example, presented by Dr. David 

 Edsall, was one of six strobiles met at autopsy in the intestine 

 of a Syrian woman who died from tuberculosis in the Phipps 

 Institute of this city. Two entire strobiles were submitted 

 by Dr. P. S. Stout, who obtained them from living patients 

 after the use of a ta?niafuge. The other instances were 

 fragments found in the dejecta and sent to the laboratory for 

 indentification before treatment. 



13. Tcenia crassicolis, Rudolph! (Path. Hist., 1106), has 

 been identified from the ileum of an eyra, Felis eyra, 

 which died in the Zoological Gardens from an intense 

 acute enteritis. Along with it there were also met in 

 the upper part of the intestine a number of examples of 

 Uncinaria canina. The single specimen of tapeworm was 

 immature, the strobile measuring 16.5 cm. in length and 

 including no ripe links. The general features of the worm, 

 save in the fact that the measurements of the head and of its 

 hooklets and of the individual proglottides were lower than 

 those usual to this worm, were quite in conformity with the 

 known characteristics of Tcenia crassicolis; but it is possible 

 that in this type of cat a special variety of the parasite in 

 question may develop and may be represented by the present 

 example.
