 genus b( 1. then both it and Moschata belong to the same year, and in the absence ol 



information as to which reallj had priority, it seems advisable to retain the name which lias 

 nerally employi 

 Regarding the remaining synonyms littl<- need be said. Ilmoni's reference of liis Cereus 

 cuéreus t<> Ok ' ereus is evidently erroneous, tint genus being founded upon the 



form now known .is c". pedunculatus, and Forbes' reference of his vestita to Edwardsia is also 

 an error. Mum ëdwards' Saccanthus, characterized by the absence of a terminal pore and by 

 : teries being all nearly of equal length, although accepted by Andres (1883) is too 



imperfectly described u> be retained, especially as its definition does not sumce to distinguish it 

 from Cerianthus. Bathyanthus, erected by Andres (1882) for Moseley's C. bathymetricus{\^-jj\ 

 may be a good genus, possibly equivalent to and therefore supplanting Roule's Pachycerianthus, 

 hut Moseley's description of the single individual examined is too incomplete for certainty. 

 Finally, it seems tolerably certain that Busch's Diantkea nobilis (1851) is the larval form ol 

 l 'eriantkus membranaceus.

 the number described in the text volumes, while others contain 74. 8g, or 100. Ii seems probable that Dei.1 \

 hut this volume and the inference is that the publishers, in the later issues of the plate volume bound in some or
