578 Cixnon A. M. Norman — Notes on the, 



tliree species^ C. opuntoides, C. salicornnria, and C. fdiformis. 

 The second of these is the Eschara fistidosa, Linne, and was 

 figured by Ellis on plate xxiii. In Ellis and Solander's 

 ■\York vre find the spelling of the name changed^ without any 

 reason, to Cellaria. 



Lamouroux, when he refers to the genus, adopts the 

 spelling Cellaria, quotes Cellularia, Pallas, as a synonym, 

 and retains only two of the species of Pallas in the genus — 

 C. salicornaria and C. opuntoides. The spelling of the name 

 was simply changed, the genus is the same, its type C. salicor- 

 naria. Cellaria mnst disappear as being an absolute synonym 

 of Cellularia. In 1817 Cu\ ier made whut was already the type 

 of Cellularia the type of a new genus which he named Sali- 

 coriuma. Now " Cellularia, Pallas^' (sic), has been employed 

 by Busk and. liincks in an entirely different sense ; and as 

 used by them does not contain any species placed by Pallas 

 in his genus. Under any circumstances therefore — that is, if 

 a type of Cellularia had not at a very early date been indi- 

 cated — Busk's usage could not be maintained. The remarks 

 of Hincks (Brit. Polyz. p. 104) should be consulted also on 

 this point. That author took a step in the right direction 

 when he went back to Solander and Ellis and to Lamouroux, 

 but a step further was required to that excellent author 

 Pallas ; and Hincks, unfortunately, used both the names 

 Cellaria and Cellularia. His Cellaria fist ulosa must become 

 Cellularia fistidosa. 



Genus Menipea, Lamouroux. 

 = TriceUaria, Fleming, 1828, = Cellarina, J. van Beueden, 1848. 

 I think it very doubtful whether Lamouroux's genus can 

 be employed for the northern forms placed in it ; Verrill 

 considers that it cannot. TriceUaria, which is the next 

 generic name in date, would scarcely be applicable. There 

 remains Cellarina, J. van Beneden.
