6c. — Burnham in Somerset (Bell, Jordan, and others) ; Torbay. This 

 must take the place of var. gracilis described by me in Journ. of 

 Couch., 1893, vol. vii., p. 260. 



var. minor Jeff.— Moulin Huet, Guernsey. Jeffreys' locality for 

 this variety is a cave in the Shetlands. He did not consider the 

 Guernsey specimens identical, but having compared the two I find 

 that tliey fairly agree ; the only character in which they differ is in 

 the Shetland examples having a larger aperture, but that is in con- 

 sequence of their being immature and lacking the thickened outer 

 lip with its usual tubercles. Otherwise, Guernsey and Shetland 

 specimens in my collection are identical in shape, size, sculpture, and 

 spire. Figured mjouru. of Conch., 1895, vol. viii., pi. iv., fig. 11. 



A very pretty form from Jersey is lavender-coloured, and deeply 

 ridged ; it forms a colony on the rocks of St. Clement's Bay, much 

 lower down the littoral zone than usual. An interesting plate, 

 illustrating many forms of this polymorphous species, will be found 

 in the Cambridge Natural History, and reproduced in the Jonr7i. of 

 Conch, for July, 1895. Two reversed specimens have been recorded^^ 

 one from Scarborough, in the Bean collection, and the other from 

 North Wales, in the Norman collection. There is also a specimen in 

 the MacAndrew collection in the Cambridge University Museum. 

 Mr. John Leckenby, of Scarborough, on one occasion offered ;^io 

 for a reversed specimen, but without result, and at the suggestion of 

 Gwyn Jeffreys started a small army of Scarborough women to collect 

 the Purpura', from the rocks at twopence a pint ; but the Scarborough 

 coast line having in time become exhausted, and this Amazon corps 

 declining foreign service, they were then disbanded, no results having 

 followed their campaign save many bushels of useless dog-whelks and 

 an expenditure of £,io or jQ\2 ! This is only half the tale. Mr. 

 Leckenby subsequently heard, through a traitor in the camp, that two 

 of the w^omen, having ascertained that his agent only scanned them 

 over previous to throwing them into his back yard, obtained access to 

 this heap, and presented the same Furpurce over and over again for 

 measurement and pay ! 



Canon Norman has placed F. tetragona J. Sow, (a monstrous form 

 of F. lapillus from the Crag) in the Alm-icidce as a variety of M. 

 erinaceus,^ in consequence of Searles Wood's son having found a 

 similar but recent form on Felixstowe beach and wishing to transfer it 

 to Murex, against the contention of Gwyn Jeffreys that it is a Furpura. 

 > But I think Jeffreys' contention the right one. Searles Wood's figures 

 (four) clearly show the short and open canal of Furpu?'a, only one of 

 them (fig. 7b) having a superficial resemblance to a Murex." The
