Herrick, Tactile Centers of Prionotus. 319 



(tractus spino-tectalis or ''lemniscus"). This again illustrates the 

 essentially local character of the chief reflex paths associated with 

 the tactile system. There is a cerebellar connection of the funic- 

 ular nucleus region which is stronger than in any other teleost 

 which I have examined. 



The visceral sensory centers of Prionotus are rather poorly 

 developed, though the visceral commissura infima and commis- 

 sural nucleus have the typical teleostean relations.
