Meaning

1. adjectiverespiratory
   Branchiæ apellantur etiam apud imperfectiores formas ea organa, ex quorum indole apparet ea ad perfectiarum organa respiratoria respondere; hæ diversis nominibus adhue significatæ sunt, ita apud Aphroditaceas elytra vel squammæ, apud Phyllodaceas cirri lamellosi, et apud Cirratulum cirri apellati.In more imperfect forms, those organs are also called gills, from the nature of which they appear to correspond to the respiratory organs of perfect forms; these have been designated by various names, thus in the Aphroditeaceae they are called elytra or scales, in the Phyllodaceae they are called lamellar cirri, and in the Cirratulum they are called cirri.1843, Anders Sandøe Ørsted, Annulatorum danicorum conspectus, page 6:
