CoturnicG communis, Bonnaterre. — As might have been expected 

 from the abundance of the species at the present clay on the Italian 

 coasts, the remains of Quail are extremely common in Tavolara. The 

 only specimen that I have thought it necessary to figure is the right 

 tarso-metatarsus (represented in fig. 12 of Plate XXXVIT.) ; but the 

 collection comprises many specimens of this bone, as well as some of 

 the tibio-tarsus, femur, coracoid, furcula, humerus, &c. Remains of 

 Quail have been recorded by Milne-Edwards {t. c. pi. 134. figs. 25, 

 56) from the ossiferous breccia of Montmorency (Seine-et-Oise).

VII. TUBINARES. 



Procellaria. — Perhaps no bird-bones are more easily recognized 

 than those of the ProceUariidcB ; some of the most characteristic being 

 the coracoid, the humerus, and the tibio-tarsus. The humerus is 

 readily distinguished from that of the Gulls by the absence of any 

 distinct tricipital fossa, while the tibio-tarsus is equally well cha- 

 racterized by the upward prolongation of its cnemial crest. Again, 

 the wing-phalangeals lack the two fenestrse which are so especially 

 distinctive of that bone in the Gavise. 



The collection from the Tavolara caves comprises, as I have said, 

 a large number of bones of Puffinits clearly referable to three distinct 

 species. The want of skeletons of all the recent species of the genus, 

 to which I have already alluded, precludes, however, the specific de- 

 termination of more than two of these forms. 



These three Shearwaters are represented by bones from nearly all 

 parts of the skeleton, including the skull. The specimens of the skull 

 are alone sufficient to indicate the presence of three species, and are 

 important in showing that all three belong to the long-beaked genus 

 Puffinus as distinct from the shorter- beaked Fulmarus. The bones 

 selected as illustrations of the three species are, however, chiefly the 

 humerus, tibio-tarsus, and tarso-metatarsus.
