 p. 218, pi. xi.,f. 13. Gale Point. We cannot be quite certain that the Green- 

 land specimens, which are somewhat imperfect, are specifically identical with 

 those of Norway. But they agree in size and all characters which can be 

 clearly made out from the specimens received. Rathke's Siphonostomum inha- 

 bile evidently belongs to our genus Brada, Mar. Invert, of Gr. Manan, p. 32.

 The specimens brought home by Dr. Hayes from the N. W. coast of Greenland 

 are of a much larger size than those found on the coast of New England. One 

 of them measured 0.57 inch in diameter. 



49. Mya truncata Lin. Port Foulke, very abundant. Nearly all the spe- 

 cimens are of the short, broadly and obliquely truncated form, with the beak 

 near the posterior end, called Uddevallensis by Forbes, which is characteristic 

 of the glacial deposits of Europe and America, and is now found living, for 

 the most part, only in high northern latitudes. The siphons of this bivalve 

 were found in great numbers in the stomach of a walrus. 



50. Saxicava arctica Desh. Mya arctica Lin., 0. Fabr. Mya byssifera 0. 

 Fabr. Saxicava rugosa Lam. Saxicava distorta Gould non Say. Port Foulke 

 large and very abundant. Among Dr. Hayes' specimens, the form arctica appears 

 in much greater numbers than that called rugosa or pholadis. The siphons of this 

 species also were found in a walrus' stomach.
