 I have Dot been able to find the reference to the occur- 

 rence of this tapeworm in above-named cockatoo, and am 

 giving this reference, pie Fuhrmann 1 (1908). 



A good deal of discussion has taken place regarding the 

 correct nomenclature of one of the above cestodes, Monir::ia 

 trichoglossi. It was originally described by Linstow 2 from 

 fragmental material collected by the Challenger Expedition 

 from Trichoglossus norae-hoUandiae. He regarded it as a 

 new species, and called it Taenia trichoglossi. In 1900, 

 Diamare' described ;i parasite Inmi (' ijclopsil i ,,<-us suavis- 

 simus and Lnrins crijl h vol Imrax, wldcli he named Paronia 

 carrinoi, this being the type of a new genus Paronia. In 

 1901, he 4 mentioned that P. carrinoi was probably identical 

 with T. trichoglossi, but thought that his name should 

 stand as the correct one on account of the imperfect 

 description of the latter. In 1901 Fuhrmann 5 after having 

 examined Linstow's original material, stated that these 

 two worms were identical, and that the genus Paronia was 

 probably synonymous with MoniesHa. He however retained 

 the name P. carrinoi. In 1902, 6 he gave a much fuller 

 account of the parasite, definitely assigning it to M oniezia. 

 In a footnote to this paper, Dr. M. Braun (p. 122) mentioned 

 that if T. trichoglossi were found to be identical with P. 

 carrinoi, then in spite of the iiisu!liei.-nt original descrip- 

 tion the former name must stand. In other words he
