Island, and Nova Scotia sand beaches (Willis). Found also on sandy 

 beaches in Nortlmmberland Strait and at many localities in the River and 

 Gulf of St. Lawrence. The most northerly locality from which this species 

 has been recorded is Salmon Bay, on the north shore of the Gulf, just inside of 

 the Strait of Belle Isle, where two young dead shells were collected at high- 

 water mark by Packard in 1861. 



Rare and of small size in the Pleistocene of New Brunswick, and at 

 Beauport, P.Q. 



LuNATiA HERDS, var. TRISERIATA (Say). 



Natica triseriata, Say (1822). 

 Lunatia triseriata, Gould (1870). 



The distribution and bathymetrical range of the var. triseriata are very 

 similar to those of the typical L. heros, but the former has not yet been 

 found on the north shore of the River and Gulf of St. Lawrence, nor in the 

 Pleistocene of Canada. 



Natica clausa, Broderip and Sowerby. 



Natica clausa, Broderip and Sowerby (1829). 

 Natica consolidata, Couthouy (1838). 



Throughout the entire region, and northward, usually at depths of less 

 than fifty fathoms. Verrill, however, has dredged this circumpolar species 

 in as deep water as 109 fathoms, in the Bay of Fundy • and the writer 

 dredo'ed a living specimen off Cap des Rosiers lighthouse in 110 fathoms, 

 coarse sand, with stones, in 1872. 



It has been found fossil at Portland, Maine ; at St. John and other 

 localities in New Brunswick ; at Anticosti, Riviere du Loup, Quebec and 

 Montreal ; also at Vancouver Island, and at many localities in Europe.

Grand Manan, Stimpson, who says that very large specimens of this and 

 the next species are " taken in the laminarian zone," V. zonata " inhabiting, 

 however, deeper water than" V. Icevigata, " which occasionally occurs at low- 

 water." Annapolis Basin, " seldom " ( Verkruzen). Fishing banks oflf
