-110- ?Puffinus, species. At the end of July, 1825, the 'Blonde' party found a "procellaria, not unlike the Procellaria alba of Linnaeus." W. A. Dixon (1866-1869) records three species of "puffinas or mutton birds," as regular breeding species. These laid their eggs "in holes dug in soft ground or between rocks." "Prians." Dixon includes "three species of prians, slate-coloured, pure white, and black", among the regular breeders of this island; but, he says, "The prians lay on the edge of a rock or stone, and the egg being of exactly the same colour is only seen with difficulty; they are quickly hatched, and in ten days the young have flown." This description of the nesting habits points to something without the Tubinares group, but evidently there are three species of breed- ing birds that appeared to belong to the same "genus" to this amateur observer. "Small petrel." Dixon reports this as an "occasional visitor" to Malden. STERNIDAE. Gygis, species. The 'Blonde' party found it in July, 1825, and this may be their Sterna Maldensis, which is described simply as "A white tarn, differing but in a few points from Linnaeus's Sterna alba." ?Onychoprion, species.
