354 Mr. C, W. Andrews on Remains of Birds 



it will be necessary to compare tliem with Pelecanus ono- 

 crotalus and P. crispus only. The latter of these is the 

 larger, and in the skeletons I have examined the bones of 

 the wing are longer in proportion to those of the leg than 

 in P. onocrotalus, in which the tibia and metatarsus are in 

 some cases as long as those of P. crispus, while the wing- 

 bones and femora are considerably shorter ; even the tibia 

 and metatarsus, however, can be distinguished, those of 

 P. onocrotalus being somewhat the more slender. 



Among the specimens are a left humerus and left ulna, 

 quite unbroken, and a right metacarpus wanting only a 

 portion of the third metacarpal. These bones agree very 

 closely with those of P. crispus, as is shown in the following 

 table : — 



Several specimens of the coracoid are preserved, and of 

 these two specimens belonging to fully adult birds are 

 smaller than the coracoids of P. crispus that I have measured, 

 and are of about the same size as those of P. onocrotalus ; 

 they may, however, have belonged to a female of the former 

 species. The other specimens, which are clearly immature, 

 are slightly smaller than those of P. crispus.

In the dimensions of the bones of the hind limb the 

 Glastonbury birds show a considerable range of variation, 

 even allowing for diflFerences of age ; for instance, one meta- 

 tarsus measures 12'5 cm. in length, while another, apparently 

 fully adult, is only ^10*9 cm. long ; this latter may have
