Clark has made of the Liicernaria? an order equivalent to the Hy- 

 droids and the DiscophorJB ; but it should be reineinljcred at the same 

 time that his Acalepha? correspond to the Hydroid and Diseo})horous 

 Medusa) of other authors, and do not include the Ctenophoriw We 

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

 Agassiz has very justly said, the Lucernariae are only pedunculated 

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

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

 free Discophora} which the Pentacriiiida) do to the Comatulidtw Their 

 mode of development may show that then* 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 species 

 of Tubularians.
