430 Mr. T. Gray on a new species of Strombuaf^iS .M 



pi. 855. f. 12 a, to which is added the following brief descrip- 

 tion : — " Buccinum bilingue Canadense^ labro Isevi, ex inferiore 

 parte raucronato^ clavicula dense adniodum striata, longa, tenui." 



Mr. Dillwyn, in his Index to the ' Historia Conchyliorum ' of 

 Lister, remarks that this figure " has been generally quoted for 

 Strombus vittatus; but I never saw that species with the lip so 

 much expanded.'' S. vittatus, Linn., a figure of which is given 

 by Lister on the same plate (f. 12 6), is perhaps the species to 

 which this shell bears the nearest resemblance, particularly as 

 regards the spire ; the expansion of the lip however reminds one 

 of S. epidromis, Linn., but its form, as may be seen on consult- 

 ing Lister's figure, is very different from either. Linnaeus, in 

 the last edition of his ' Systema Naturse,' does not quote Lister 

 for his S. vittatus, no doubt for the reason given in the note at 

 p. 1210'; but Martini has appropriated both figures on Lister's 

 plate to S. vittatus, in which he has been followed by Gmelin. 

 Both of these authors had evidently, like Dillwyn, never seen 

 the shell, but it is somewhat surprising that they should have 

 confounded two species so very unlike each other. 



As we are not aware of any recent conchological work in 

 which this shell is taken notice of, and having every reason to 

 believe that this is the only specimen known to exist in any col- 

 lection, at least in this country, we have been induced to publish 

 it anew, and to point it out to collectors and others who take an 

 interest iti conchological pursuits. 



By the kind permission of Dr. Wm. Couper, the Professor of 

 Natural History, we have been allowed to examine the shell and 

 take a drawing of it. In describing it anew, we propose to give 

 it the name of the author, and the only one we believe who has 

 figured it, whose work is a lasting memorial of unwearied dili- 

 gence and perseverance.

The colour and disposition of the markings very much re- 

 semble those of S. vittatus, succinctus, and others belonging to 

 the same group, and for this reason, as well as from its general 

 form, we are inclined to suppose the species to be oriental. 



We would only remark further, that the shells which belonged 

 to Dr. Hunter were purchased by him from the trustees of 

 Dr. Fothergill, and it is not at all improbable that this specimen
