supposed to be of the same species as the former, but comparison 

 proved them to be different. Their characters are as follows : Tania 

 iirnigera = T. pestifcra in part, Proc. Acad. Nat. Sci., 18.55, 443- 



Head urniform or cruciform, summit projecting in a pedicillate 

 rounded knob or disk, or rostellum, unarmed. Bothria spherical, 

 prominent. Neck, short or longer, obconic. Body narrowest at 

 commencement and gradually widening to near the posterior ex- 

 tremity. Anterior segments narrow, annular, soon becoming cuneate, 

 graduall}^ longer and wider, and then campanulate with prominent 

 back border. Length from i to 2 inches, ordinarily about 15 lines ;

Dr. B. H. Warren, of West Chester, a zealous ornithological ob- 

 server, has submitted to my examination a collection of intestinal 

 worms, recently obtained by him during an expedition to Florida. 

 Among these are a number of tapeworms, of which most appear to 

 be undescribed species. They are as follows : 



Taenia odiosa.- Head hemiovoid to conical, unarmed : bothria sub- 

 terminal, spherical, near together ; neck none ; body immediately 

 after as wide or nearl}' as wide as the head ; anterior segments short, 

 linear ; succeeding segments all wrinkled annularly, the more an- 

 terior band-like, the posterior barrel-shaped. Generative apertures 

 lateral, mostly not visible. Length iVt, to 2 inches. Head 0.3 to 

 0.45 mm. wide ; body just behind about as wide as the head ; anterior
