conarial (ko-na'ri-al), a. [< conarium + -/.] 
Of or pertaining to the conarium, or pineal body 
of the brain. Conarial fossa, depression of the 
roof of the skull of some animals, in which the conarium 
is lodKcil. Conarial tube, the more or less extemleil 
cavity or canul of the pineal body, now commonly suppose,! 
Ui lie the remnant of the passage by which in vertebrates 
generally the primitive cavity of the myctcMccphalon 
eomiiiiinicateil with the outer surface of the head. In 
man and the higher vertebrates generally the conarium 
appears to be deep-seated in the brain ; but this is decep- 
tive, at ii I merely owing to the overgrowth of the cerebrum. 
The coniiriuni is morphologically on the superior surface 
of the brain, whatever IU apparent situation, and there 
is much reason to suppose that the large openings of the 
top of the skull in sundry Tertiary mammals, called the 
parietal foramina, indicate the extension of the conarial 
tniie to the surface, und the formation there of a visual 
or other special-sense organ. On this view, the conarium 
is the vestige of an extinct eye. See ciinariunt.
