and the operculum is wrongly shaped. Jeffreys' plate figure is much 

 too broad, and it should not he spirally striated nor have such a 

 broad glaze on the pillar. 



Gwyn Jeffreys has recorded a Buccinopsis slriata, which he vaguely 

 assigned as "another interesting addition to the Shetland fauna." ^ 



Triton CUtaceus L. — A very fine living specimen, dredged by me 

 off St. Martin's Point, Guernsey, in 22f., in 1885, exceeds the dimen- 

 sions given by Jeffreys. This is the only example that has been 

 obtained alive in recent years. Unfortunately, the operculum of this 

 particular specimen was lost through being placed on a table-cloth 

 while extracting the animal, and then whisked away, with several 

 other small rarities, before it was remembered. Although very rare in 

 a living state, dead specimens picked up on the shell beaches now 

 and again clearly indicate its continued presence among the Channel 

 Islands. Four dead specimens, though very much worn, are in the 

 Guernsey Museum from the MaccuUoch collection, and another dead 

 specimen was picked up on the beach at Alderney by a casual visitor 

 in 1902. Guernsey examples belong to a form named by Locard 

 T. danieli, which is larger and broader than the Mediterranean one, 

 with a thinner and paler epidermis. 



T. nodiferus Lam. — No addition has been made to the " three 

 living specimens" of this shell found off Guernsey in 1832. One of 

 these recorded specimens is still in the collection of Dr. Lukis, now 

 in the possession of his daughter. But since the death of the Doctor 

 in 1865, this interesting little collection of Guernsey shells has been 

 kept hidden away and doing no good to anybody, instead of being 

 placed in the very excellent Museum established in that island. It 

 may be that the "three living specimens" cited by Gwyn Jeffreys 

 were survivals from a period when the species was perhaps less rare 

 in the Channel Islands. I have never met with so much as a frag- 

 ment of the shell, though I have thoroughly worked through the 

 whole of the islands more or less since i860. 



Murex erinaceus L. — Linne's type-form, which is the var. 

 sculpta of Jeffreys, has been dredged only occasionally off Guernsey, 

 but in 1868 I discovered a numerous colony at Herm Island, during 

 a very low tide, concealed under stones. Since then, though the 

 species has always been plentiful at the same spot, they have reverted 

 to the usual form common on our coasts. I cannot account for this 

 curious circumstance. All specimens obtained from other parts of our 

 coasts belong to the var. tarentina of Lamarck, which is the form 

 figured and described (erroneously) in British works as the type. In 

 the true type form, the spiral ridges are vaulted where they cross the
