This name includes material that is similar in morphology and close in size to those of the current Pt. deserta , Pt. feae , and Pt. cahow , so they could be included in any of these species. Nevertheless, it also remains possible (even probable) that they represent one or more cryptic unknown species ( Figs 3 View Figure 3 , 4 View Figure 4 , 6 View Figure 6 , 7 View Figure 7 ; Tables 2 View Table 2 , 3 View Table 3 , 4; Supporting Information, Figs S1–S8).
Material and collection information: See Supporting Information, Table S1.
Horizon: Late Quaternary–Recent.
Distribution: Porto dos Frades (Porto Santo, Madeira Archipelago ), Madeira Island, and the Azores (São Miguel, Terceira, Graciosa, São Jorge, and Pico).
Remarks: The 14 C date of two fragments of ulna (proximal right and distal left) of one specimen of Pterodroma sp. B from Furna das Torres, Pico (Azores): RICH-21398 and 1654 ± 30 BP, was calibrated with 38 ± 139 (∆ R ± SD) providing the interval 665–1263 CE ( Table 1 View Table 1 ). These bones are longer than those of the current Pt. madeira ( Tables 2–4 View Table 2 View Table 3 ; Figs 3 View Figure 3 , 4 View Figure 4 , 6 View Figure 6 , 7 View Figure 7 ). The ANOVA performed with the ulna lengths of the current Pt. madeira and those from these material [from Madeira Island, Porto dos Frades (Porto Santo), and Graciosa, Pico, and São Miguel (Azores)] indicate a smaller size of Pt. madeira bones (F 5,62 = 18 526; P <.001). The carpometacarpus from Madeira Island, Porto dos Frades (Porto Santo), Graciosa, and Pico are longer than those of the current Pt. madeira (U = –2.170; P =.03, U = –2.846; P =.004, U = –2.536; P =.011, and U = –2.449; P =.014, respectively). In addition, the ANOVA performed with the tarsometatarsus lengths of the current Pt. madeira and those of Pterodroma sp. B from the island of Madeira sites and from Porto Santo (Porto dos Frades) indicate a small size of the former (F 2,41 = 53 326; P <.001).
The material of this genus found in the Canary Islands (El Hierro) ( Rando 2002) is of a similar size to those of this group ( Tables 2 View Table 2 , 4; Figs 3 View Figure 3 , 4 View Figure 4 , 6 View Figure 6 , 7 View Figure 7 ). No differences were found in the carpometacarpus lengths between the fossil bones from El Hierro, the fossils from Pico (U = –0,816; P =.414), São Jorge (U = –0,655; P =.513), Porto dos Frades (U = –1528; P =.126), and the bones of the current specimens of Pt. cahow (U = –1061; P =.289) and Pt. deserta (U = –0,707; P =.48).
