species in several respects differ distinctly from those from Australia 

 as well as from inhaerens (O. F. Müller) and chela Mortensen. All 

 the American species at hand except the ten-tentacled species 

 transgressor, are characterized in having the anchors from the 

 posterior end of body longer and more slender than those from the 

 anterior end, and furthermore in having two distinctly different 

 sizes and shapes of ciliated funnels, of which the larger ones are 

 in shape very like the flower of a Lamium or an Antirrhinum. 

 This is not the case with the Australian species or with inhaerens 

 and chela, in which species the anchors from the two ends of the 

 specimens are not distinctly different, and the ciliated funnels, 

 though of varying size, are of only one sort being more or less 

 fan-shaped.
