There is much confusion in reference to this species and the following (elongata), 
owing to the uncertainty as to which form Montague’s figures were intended to represent 
and his description to attach, the two figures of Montague (one of the interior and the 
other of the exterior) being inconsistent with each other. Both were united by me in 
the ‘Crag Mollusca’ under the name swbauriculata, the following species (e/ongata) beng 
shown only as var. elongata (fig. 3c). Mr. Jeffreys has, in ‘ Brit. Conch.,’ given a new 
specific name (clliptica) to one of the two forms, which, he says, is that one from which 
Forbes and Hanley appear to have taken their description, and he has assigned 
Montague’s name of swbauriculata to the following species (elongata) ; and he adds that the 
species to which he thus assigns the name ed/iptica has not, in his belief, been found south 
of the Hebrides. Mr. Hanley, however, assures me that the specimen from which the 
figure and description in the ‘ Brit. Moll.’ were taken came from the British Channel. As 
the other form has long been described under other names, it seems to be adding to 
«<omplexity to introduce the name el/iptica for either; and I have therefore retained 
Montague’s name for the least elongated of the two forms which occur in the Crag, and 
an doing this I adhere to Forbes and Hanley’s view of the matter.

This elongated form, figured by me as a variety only in ‘ Crag Moll.,’ must, I presume, 
now be regarded as a distinct species, the only question being that of name. As it is clear
