578 Canon A. M. Norman — Notes on tlie, 



three specieS; C. opuntGides, C. saJicornaria, and C. fiViformis. 

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

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

 work we 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- 

 nai'ia. Cellaria must disappear as being an absolute synonym 

 of Cellularia. In 1817 Cuvier made w hut was already the type 

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

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

 by Busk and Hincks in an entirely different sense ; and as 

 used by them does not contain any species placed hy 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 Avas required to that excellent author 

 Pallas ; and Hincks, unfortunately, used both the names 

 Cellaria and Cellularia. His Cellaria fistulosa must become 

 Cellularia fistulosa. 



Genus Menipea, Lamouroux. 

 = TriccUaria, Fleming, 1828, = Cellarina, J. van Beneden, 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. Tricellaria, which is tlie next 

 generic name in date, would scarcely be applicable. There 

 remains Cellarina, J. van Beneden.

I am indebted to the late Prof. J. van Beneden for a 

 portion of the type spet'imen of his Cellarina gracilis in the
