  • * The common and scientific names have been updated (originally cited as sand shark, Prionace glaucus).

  • Although the original publication documents an adenoma, subsequent reanalysis suggests that the lesion was actually a hepatocellular carcinoma as evidenced by the invasive margins. (J. Harshbarger and G.K. Ostrander, unpublished data.)

  • The original report of this neoplasm (16) was of a reticulum cell sarcoma in a brown shark (Carcharinus milberti). The species name, common name and diagnosis were subsequently revised (17) as indicated.

  • § Originally reported as Scyllium catulus.

  • The original report incorrectly listed this individual as a spiny dogfish, Squalus acanthias.

  • Originally reported as Squalus sucklii.

  • ** Formerly known as the blue skate.

  • †† Orginally reported as a blue skate, Raia macrorhynchus.

  • ‡‡ Originally reported as hepatocytic adenoma.
