Clark has made of the Lucernarise an order equivalent to the Hy- 

 droids and the Discophorse ; but it should be remembered at the same 

 time that his Acalepha3 correspond to the Hydroid and Discophorous 

 Medusos of other authors, and do not include the Ctenophorae. We 

 would reduce this group to the level of a suborder ; for, as Professor 

 Agassiz has very justly said, the Lucernarise are only pedunculated 

 Discophorse, and have no claim to be considered as a group of a higher 

 value than a suborder. They seem to bear the same relation to the 

 free Discophorse which the Pentacrinidse do to the Comatulidse. Their 

 mode of development may show that their separation as a distinct sub- 

 order is giving even too much weight to their embryonic character ; 

 and we may find, with future investigations, a somewhat similar rela- 

 tion between them and the Strobila, from which free Discophoras are 

 produced, as that which we have between the free and sessile species 

 of Tubularians.
