muddy bottom, very rare (Jeffreys). Also British Channel slope 

 69of. ('Porcupine')! Diaphana globosa and D. hyemalis oi G. O. 

 Sars are synonyms of this. 



Accra bullata Miill. — Herm Island, a dwarf form |-in.in length. 

 The usual size is f-in. by ^-in. 



var. nana Jeff. — This is a line and a half in length by one in 

 breadth. 



var. farrani Norman (Journ. of Conch., 1893, vol. vii., p. 264). — 

 Connemara (Farran) ; dredged once in quantity, but not since redis- 

 covered. Dimensions if -in. by i|^-in. An odd specimen was 

 dredged alive off Boffin Island, in the west of Ireland, by Mr. Wood- 

 ward in 190T, and subsequently occasional specimens have been 

 trawled by the Irish Fishery Commissioners in the same district, thus 

 showing that it is not extinct nor exterminated. 



Actaeon tornatilis L. — Aldemey and Herm, three dead speci- 

 mens on tlie beach (Marquand) ! These are the only records from 

 the Channel Islands. The largest specimens come from Pendine, 

 and sometimes attain |-in. in length, while a dwarf variety from the 

 Doggerbank is only ^-in. 



var. subulata S. Wood. — Knapdale Lochs iif., Dornoch Frith. 



var. tenella Lov. — Aberdeenshire, deep water; off Cape Wrath 

 68f., and Shetlands 5if, (Simpson)! Doggerbank 3of., Loch Bois-

var. bullseformis Jeff. — Torbay i2f., Doggerbank 3of. 

 A. exili's Jeff.^ has been dredged by the 'Porcupine' in the 

 Atlantic off Ireland in i2i5f., and by the 'Triton' in the Shetland- 

 Faroe Channel in 57of. In the same volume of the Annals,^ but two 

 months later, it was described by Mr. Alfred Bell as a Crag species 

 under the name of ? A. ethe/idgii, and this was repeated and figured 

 by Searles Wood^ in his work as A. etheridgei, with A. exilis Jeff, 

 cited as a synonym, and the remark — " I presume this is the shell 

 called exilis by Jeffreys in his list to Mr. Prestwich's Red Crag 

 paper. "^ Searles Wood here assumed that Jeffreys' list name in the 

 Geological Society's Journal was its first record, instead of in the 

 previous year and two months before Bell's paper, and it has 

 apparently escaped notice because Gwyn Jeffreys ignored A. etheridgei 

 in all subsequent citations of ^. exilis. A. Bell describes his species 

 as having 5-6 whorls, but Wood's figure (not very good) exhibits 4-5, 

 while Jeffreys' dimensions indicate an immature specimen. It has 

 actually 5-6 whorls, as stated by Bell. One of the specimens pro- 

 cured by the 'Triton ' in the Shetland-Faroe Channel was described
