NOTE ON CESTODE NOMENCLATURE. 
In many of the cestodes there occurs at the beginning of the 
germ duct an organ, chiefly muscular in structure, which engages 
the germ cells on their release from the germarium and forwards 
them into the germ duct. From its characteristic movements in the 
discharge of this function the organ was well named “ Schluck- 
apparat" by Pintner, who made the first extended study of its occur- 
rence and structure. Its presence has been generally recognized by 
investigators on cestode structure since then, and the term used by 
Pintner has been widely employed even in French and English 
papers. The evident disadvantages of such terms as are unpro- 
nounceable and unintelligible to students unfamiliar with the Ger- 
man and are furthermore incapable of inflection, serve as my excuse 
for calling attention to a term in use in the laboratory here to desig- 
nate this structure, namely, odcaft. Formed on the analogy of 
Leuckart’s generally accepted term “odtype” for a neighboring 
structure in the reproductive apparatus and conveying the appro- 
priate idea suggested by Pintner, the term **oócapt " has proved in 
use both convenient and precise. As it is to be used in papers now 
being published by some of my students, this explanation is also 
necessary in order to prevent possible confusion or misunderstanding 
regarding its origin and meaning.
