Paris, Roret: xv + 442. Atlas, 80 pls.

–Allen 699. Sirs., treated as a "tribe" of the Order Cetae: Manatus americanus, M. senegalensis, M. latirostris, Halicore dugong, and Stellerus borealis (401-404). Allen calls this work "an indiscriminate compilation, useful mainly as giving a list of the species described up to this date." The atlas (Allen 700) apparently contains no illustrations of sirs.
