In the course of dissecting a parakeet (Brotogerys tirica) sent to me for examination, I came across several large tapeworms of the genus Cotugnia in the duodenum. They did not agree with any of the species previously described and, upon closer examination, showed so many points of difference as to justify the creation of a new species for them. I propose the name Cotugnia brotogerys for this species.
