^ Carnegie numbers are sample, not station numbers. ^tA = Murray (1902, 1906); M and L = Murray 

 and Lee (1909); M and R = Murray and Renard (1891); T = Trask (1932). 3 The designations for deposit 

 types are those of the authors referred to. The following abbreviations are used: br = brown, bu = blue, 

 ca = calcareous, cl = clay, diat = diatom, dk = dark, f g = fine-grained, glob = globig:erina, gn = green, gr = 

 gravel, gy = gray. It = light, m g = medium-grained, oz = ooze, pter = pteropgd, radiol = radiolarian, rd = 

 red, s = sand or sandy, sil = siliceous, st = silt or silty, vole = volcanic. * probably a pelagic sample.
