346 Mr. J. G. Jeffreys on the recent species of Odostomia 



latiores et ad basim ultimam testae excurreutes, 6 costellis vix | 

 aliorum inagnitudine clathratse ; anfractus 7, convexiusculi ; apex 

 subacutus ; sutura profunda et subobliqua ; apertura rotundato- 

 ovalis ; peristoma fere continuum et non reflexum ; umbilicus di- 

 stinctus, angustus. Long. ^, lat. Jq ^'^^' 



Birtabuy Bay, co. Galway, where a single specimen was found by 

 Mr. Bailee. 



Very distinct from any of its congeners.

 shire. Loch Fyne and west coast of Scotland (Mr. Barlee). 



A local species. 



Var. a. testacei coloris ; costse adraodum pauciores. 

 Exmouth (Mr. Clark, who gave to this variety the MS. name of 

 Jeffreysii). Fishguard. Dartmouth ; Milford Haven (Mr. MacAn- 

 drew). Guernsey (Mr. Bailee). 



Local and rare. 



Fragments of a shell resembling this variety, but stronger and 

 of a pure glossy white colour, the ribs being also much sharper 

 and more distant, occuiTcd to me in dredging off Fishguard (in 

 thirty fathoms water) in 1842. It may be the Turbo marginatus 

 of Montagu. In Turbo coniferus (Mont.) the ribs are described 

 as undulating, and in his denticulatus there occur transverse 

 striae.
