The label accompanying the specimens No. 153 identified them 

 as A. chilensis LEsst)N, and the Identification having been made on 

 living individuals lends strong- support to the results obtained from 

 the study of the preserved specimens. 



Some individuals have the form of a low dome with the tentacles 

 almost concealed, while in others the column is a low cylinder 

 (Figs. 48, 50), the tentacles and disc being completely exposed and 

 the stomatodaeum somewhat everted. The base is of the adherent 

 type, some of the individuals from Calbuco being attached to hydroid 

 Sterns around which the base is wrapped. though there is no fusion 

 of the edges. The column when fiüly expanded is smooth and 

 destitute of Verrucae ; when contracted it shows distinct longitudinal 

 folds, especially towards the summit of the column. Slight rounded 

 eminences, each of which is a cinclidal tubercle, can be observed 

 over the surface of the column, apparently without regularity 

 (Fig. 49), though somewhat more abundant in the upper part and 

 rare below the middle; acontia protrude through the openings in 

 some individuals. 



The margin is smooth, except when the longitudinal folds already 

 mentioned occur on the upper part of the column, and the tentacles 

 are moderate in length, rather slender, elongate-conical in form and 

 markedly entacmaeous. They are arranged in four or five cycles, 

 the innermost consisting of twelve members, so that there is a
