    • 1921, W.C. George and and H.V. Wilson, “Sponges of Beaufort (N.C.) Harbor and Vicinity”, in Bulletin of the United States Bureau of Fisheries[1], volume 36, page 150:
      This is at least defensible, for the twisting of the chela is in itself a structural feature that is sigmalike; that is, the twisted chela is intermediate, in respect to the shape of the spicular axis, between the sigma and the normal chela, although in other respects it is a perfectly differentiated chela.
    • 1976, E.W. Caspari (editor), Advances in Genetics, Volume 18, page 36:
      They predicted that there should be other sigmalike factors that would select other classes of promoters in response to the cell's needs.
    • 2013, Harry Harris (editor), Advances in Human Genetics, page 291:
      agents which stimulate transcription suggest that sigmalike factors also exist for the eukaryotic polymerases.
