present rules of nomenclature it seems that it mu?t be adopted for 

 the genus now known as Cytherea and in any case it precludes the 

 use of ( 'attiste in ornithology. 



As regards Aglaia, while its previous use in botany does not, ac- 

 cording to our present canons of nomenclature, preclude its use in 

 ornithology, I find, nevertheless, that it is equally as untenable as 

 < 'alliste. 



In 1804 Renier (Prospetto della Classe dei Vermi, p. 16) proposed 

 Aglaja for a genus of mollusks now generally known as Doridium, 

 hut for which Aglaia must be revived as recently pointed out by 

 Prof. Pilsbry. 



In 1825 Escholtz proposed Aglaia for a genus of Siphonophora, 

 and as these authors both antedate Swainson's publication, the name, 

 of course, cannot be used in ornithology. 



Subsequently Aglaia has been proposed in 1850, by Albers, for 

 another genus of mollusks and in 1869, by Brady, for a genus of 

 Crustacea, in both of which connections it is obviously untenable. 



In view of these facts ornithologists will, I think, be compelled to 

 adopt Gray's name for the genus of tanagers, the synonymy of which 

 will stand as follows :
