Mus. Ipswich, Stanley Coll. 

 [The ' ' boxstone ' ' mould so closely approximates to the shell figured by 

 Sacco that it may be regarded as the same species ; the more so because 

 V. multilamella is somewhat variable in outline.]

 [The shell quoted or figured by Koninck, Nyst, Eavn, and other writers as

 English shell of that name.]

 may be a variant of this species.]

Mactra triangulata, S. V. Wood, Mon. Crag Moll., 1850, pt. ii, p. 325, 



pi. xxi, fig. 21. Stanley Coll. 

 Mactra trinacria, Speyer, Palasontographica, vol. xvi, p. 34, pi. iii, fig. 4, 



1861. Mus. Pract. Geol. London, York. 

 [The principal difference between M. triangulata and M. trinacria seems 

 to be that the latter forms a more equilateral triangle than the other. Both 

 are probably related to the recent M. elliptica.']
