MUREX. 483 



M. MINIMUS, Montagu. 

 Lachesis minimus, Brit. Moll. iii. p. 376, pi. 101. f. 7, 8. 



The Triton elegans, Brit. Moll. vol. iii. p. 443, is exotic. 



Sectio II. Testa inflata, Icevis, spiraliter striata. Canalis effusus, plus 

 minusve elongatus. Apertura ovalis. Columella mutica, rarius subaspera, 

 aut fastigiata. Operculum corneum. 



Fusus, Lamarck et Auctorum. 



The Murices of this section are the Fusi of authors, most 

 of which are deep-sea species, as the M, antiquus, M. Turtoni, 

 M. Norveyicus, M. Berniciensis, M. Islandicus, &c., and the 

 M. borealis. None of these, except the M. Islandicus, occur 

 on the southern coasts, and that we have had no opportunity 

 of examining for several years ; but for the type of the animal 

 of the enumerated species, we refer with perfect confidence to 

 either of our descriptions of the M. erinaceus, M. lapillus, 

 M. undatus, or any other in our list, which will furnish every 

 essential generic character; and I fully expect to have it in 

 my power, by the examination of live specimens of M. Islan- 

 dicus, to show the correctness of their assigned position as 

 members of the genus Murex. I can say nothing of the 

 animal of M, borealis, which is admitted here as probably 

 belonging to this section.
