Referring to this paper Heppell (1961) said that Marrat mentioned "the 

 extensive shallow sandy shores of Lancashire and Cheshire" and concluded 

 that substrates in the Liverpool Bay area were tolerable. It is inferred 

 that some other factor (probably water temp) must have been responsible 

 for failure of this introduction. - J.L.M.

According to Heppell (1961) Marshall quoted the Manchester City News as 

 describing the quahog as "bidding fair to compete with the familiar cockle." 

 Living specimens from the Humber estuary were exhibited at the Manchester 

 meeting of the Conchological Society. - J.L.M.

Observations of mortality and growth in plantings of small soft-shell clams, 

 Mya arenaria, and small quahogs, Venus hybrids, in the Niantic River. Suppl. 

 Rept. to the Waterford-East Lyme Escallop Commission, April 30, 1956. (Issued 

 concurrently with the report titled: "Studies of the Niantic. River , Connecticut, 

 with special reference to the bay scallop, Pecten irradians .) 



The clams used in this experiment were a cross between Venus meroenaria and 

 Venus cam-pechiensis , about half female mercenaria crossed with male 

 oampeohiensis and half the reverse. Three plantings were made: one off 

 Camp Ribicoff; one off Saunders Point; and one up-river at the houseboat 

 "Walrus". All were' intertidal, but so close to extreme low tide that they
