Clark has made of the Lucernaritfi an order equivalent to the Ily- 

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

 time that his Acalepha3 correspond to the Hydroid and DLscophorous 

 Medusa? of other authors, and do not include the Ctenophora?. We 

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

 Agassiz has very justly said, the Lucernarise are only pedunculated 

 DiscophorfB, 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 Discophora? Avhich the Pentacrinida; do to the Comatulidiv. Their 

 mode of develojiment 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 Discophora? are 

 produced, as that which we have between the free and sessile sj^ecies 

 of Tubulai'ians.
