Cestoids TcenitB. 265 



E. Valvatum. Rectangular. Ciliary crown at month ; two 

 posterior. I,ength, 214/n. 



Diplodinium Uncinatum. Ciliary crown at anus. Length, 

 goo/*. 



D. Unifasciatum. Two anterior peripharyngeal ciliary crowns; 

 one posterior. lyength, 230/x. 



Spirodiniuni Equi. Spiral ciliary crown anterior to posterior 

 ends. I,ength, 230/*. 



Triadinium Caudatum. Three ciliary crowns, one anterior 

 two lateral. Length, 300/A. 



These are non-pathogenic and grow in the vegetable infusion 

 as they do out of the body in similar mixtures. 



Organism of Indeterminate Species. 



Globidium Leuckarti. Max Flesch found in the villi of the 

 small intestine of a horse, an elliptical or .spherical organism 8ofi 

 long by 70ju. broad, but encreasing in certain cases to i6oj«. or even 

 340/t in length. It contained many refrangent spherical bodies, 

 generally distributed or enveloping a central protoplasm, and 

 sometimes a pyriform body. The most plausible suggestion is 

 that it belongs to the sarcosporidia. 



This parasite was mildly pathogenic, being surrounded by 

 slight inflammation of the intestinal mucosa. 



CESTOIDS. T^NI.^. 



Taenia Perfoliata. Head very large, tetragonal, with cup- 

 shaped suckers, but without proboscis or booklets, segments very 

 short and broad, encreasing in breadth to 2 mm. in the ninth, 

 narrowed at the anterior border, and overlapping the next seg- 

 ment behind. First six or eight segments are non-sexual, from 

 this to the 19th they are male, the three next are hermaphrodite, 

 and the terminal ones essentially female. Total length 26 to 

 28 mm. (may reach 80 mm., Rudolphi). Ova polyhedral by 

 packing together and very active embryo. Larva unknown. 

 Habitat: Caecum and small intestine, rarely the colon. Common 

 in Germany, Russia, Scandinavia, South of France and some por- 

 tions of the United States,
