THE VOYAGE OF THE 'CHALLENGER/ 371 



Of the Cecomorphae, " the Procellariidse are aberrant forms, inclining 

 towards the Cormorants and Pelicans amongst the Desmognathae " (loc. 

 cit. p. 458). 



1 871. Gr. E. Gray, in the l Hand-list of Birds ' *, places the Procellariidae 

 between the Uriidae and the Laridaa in his order Anseres. They are 

 divided into three subfamilies, corresponding to those already adopted 

 by Bonaparte and Cones. 



J. Eeinhardt, in the same year, in his paper on the " Os crochu," or 

 uncinate bone, in the skull of birds t, records its presence in nearly all the 

 genera of this family that he has examined. In a note on p. 339 he 

 corrects Professor Huxley's statement as to the usual absence of basi- 

 pterygoid facets in the Petrels, such being only absent in the Albatrosses 

 and Procellariinae (" Stormsvalerne "), present in all the rest. 



1872. Carl T. Sundevalli makes the Tubinares the fourth cohort of 

 his order Natatores. He adopts the same three subfamilies as Bonaparte, 

 Coues, and Gray. 



1873. Eeinhardt describes and figures two peculiar ossicles, of the 

 nature of sesamoids, developed at the elbow-joint of these birds in the 

 tendon of origin of the extensor metacarpi radialis lonyior. The existence 

 of such an ossicle in the genus Puffinus had already been described by 

 Meckel ||, and Eeinhardt finds two similar ones developed in the Alba- 

 trosses, as well as in the genera (Estrelata, Puffinus, Majaqueus, and 

 Adamastor of the Procellariinae. In (Estrelata fuliyinosa and bulweri, 



Diomedea chlororhyncha, and Phoebetria fuliginosa, he states that the Zool. Chall. 

 smaller of these ossicles is wanting, though the larger is still developed. Exp. vol. iv. 

 In a table he proposes the annexed classification of the Procellariinae. 



I. Wing-ossicles present. Twelve rectrices. 



a. Puffineae 



(Estrelata, Puffinus, Majaqueus, Adamastor. 

 II. Wing-ossicles absent. 



First primary longest. 



More than twelve rectrices. 



b. Pulmareae 



Ossifraga, Fulmarus, Daption.
