 The body f " where it joins the stem, is bellied, becomes 

 farther above somewhat constricted, and at the uppermost 

 end again widened, whilst the margin spreads itself out- 

 wardly round about;" as long as the pedicel: the pedicel 

 "cylindrical, slender" abruptly expanded into a broad 

 disciform base ; the four camerae very large, widened in 

 the base of the pedicel, rather abruptly narrowed just 

 before they open into the cavity of the urn, oblong ovate 

 in a transverse section ; they nearly meet at the centre of 

 the pedicel, of the radius of which the greater diameter of 

 each camera occupies about four fifths, the lesser diameter 



* In the diagnosis which Sars gives in the above cited paper, he says, " corpus- 

 cula marginalia nulla;" but as he immediately afterwards remarks that "This 

 remarliable form, which, perhaps, rightly forms a peculiar genus ('Carduella, 

 Allman") separated from the other Lucernarians, " &c., &c., and prefaces his 

 diagnosis by reference to the Fauna Littoralis and Carduella eyathiformis, All- 

 man, Quart. Journ. Mic. Soc, April, 1860. in both of wiiich papers marginal corpuscles 

 are certainly described, I can only believe that Sars has made a slip of the pen, 

 or that he means to say these bodies being identical with the tentacles, cantiot be 

 considered in the light of marginal bodies or anchors. In the second paper quoted 

 he also says, " L. eyathiformis, Sars, which lately has been offered as a new 

 genus, under no less than three names: Depastrum, Gosse; Carduella, Allman; 

 and Calicinaria, Milne Edwards." Sars has lately sent me specimens of all ages, 

 which certainly have the ''corpuscula marginalia." 



t As my specimens are alcoholic preparations, I quote from Sars' Fauna Litt. 

 Norveg. in regard to such features as are observable only in a living state.
