Diagnosis: All the bones of this species are much smaller than those of C. lignorum from the main island of Madeira. Hindlimb bones are close in size to those of C. coturnix and C. gomerae ( Table 1), but with smaller and more slender coracoid and forelimb bones ( Fig. 3). Coturnix alabrevis shows similar bone lengths and proportions to the extinct quail from São Vicente ( Cape Verde). All forelimb bones and the femur of both species are similar in size, but the tibiotarsus of C. alabrevis is longer and the tarsometatarsus slightly larger ( Figs 3, 5).

Description and comparisons: In addition to the differences in length, some characteristic features in comparison with C.coturnix can be identified:a longer and stouter premaxilla; slender humerus with a less developed fossa pneumotricipitalis and crista deltopectoralis; slender ulna with a smaller cotyla dorsalis; slender coracoid with a small labrum internum coracoidei; a stouter femur with a deeper fossa poplitea and crista tibiofibularis more prominent, and with the condylus lateralis and medialis more robust; stout tibiotarsus with a higher crista patellaris, crista cnemialis lateralis and crista cnemialis cranialis more prominent, and a deeper fossa retrocristalis; a more robust tarsometatarsus with cotyla medialis and cotyla lateralis wider and deeper, and bigger trochlea metatarsi II, III and IV.
