 eoinmoii that this species is of frequent occurrence in man 

 in America. Doubtless the parasite occurs in this country, 

 as is indicated by the above experience with the bladder- 

 worm stage; but it is much less frequent than is usually 

 believed, specimens of the beef tapeworm, Tcenia saginata,

S. ('ijxIircrcuK jiixiformix (bladderworm of Tcenia serrala, 

 (ioc/.e. of dog), obtained at (ialveston, Texas, by Dr. J. J. 

 Terrill from the liver of a common laboratory rabbit, Lepus 

 ilomi-x/ii'iix i Path. Mns., 20). 



!). Hydatidcyatt (bladderworm stage of Tcenia eckinococciu, 

 v. Siebold, of dog) have twice Ix-en received for study. In 

 one instance several daughter cysts and a portion of the 

 mother cyst wall of a large subperitoneal hydatid (Path. 

 Hist., 1900) from a man, a native Pennsylvania!!, a patient in 

 the Scranton State Hospital, at Scranton, Penna., by Drs. J. 

 Cohen and T. O. Williams. The daughter cysts submitted 

 were barren, but showed the remnants of the cestode heads; 

 they were unusually large, being between three and four 

 centimeters in diameter. The second example (Path. Hist., 

 1717) was met in the lung of a gazelle, Gazella dorcas (P. Z. G. 

 Lab., 1145). The cyst and contained daughter cysts in this 

 instance were of the usual type, and numerous examples of 

 echinococci and their hooklets were met in the examination. 



10. Plerocercmds of an unknown bothriocephalus (Path. 

 Hist., 1691) were obtained from the liver of a wood ibis, 

 Tantalus loculalor (P. Z. G. Lab., 960). There were five 

 of these larva' in the host. The usual rule for such larval 

 Iwthriocephalus worms is that they occur in fish or other 

 habitants of water and later develop to adult stage in another 

 host devouring the fish; but while it is unusual to meet with 

 them in the present type of host, it is neither impossible nor 

 unknown, and it is to be presumed that the free-swimming 

 embryo was. obtained by the bird with water swallowed.
