belonged to a hen-bird. As already mentioned, the tibia and 

 metatarsus of P. onocrotalus are almost of the same length as 

 those of P. crispiis, and in fact, in the two skeletons from 

 which the measurements of the wing-bones given above are 

 taken, the metatarsus of P. onocrotalus is actually the longer. 

 At the same time, both it and the tibia are easily dis- 

 tinguishable, both from those of P. crispus and of the 

 Glastonbur}^ Pelicans, by their more slender build.

Tt will therefore be seen that so far as length is concerned 

 there is no reason for regarding the fossil metatarsi as other 

 than those of P. crispus, which they closely resemble in all 

 respects. 



Most of the tibise are those of young birds, but one adult 

 specimen agrees very closely with a tibia of P. crispus 

 with which it was compared, and in both bones the extensor 

 bridge was incompletely ossified ; in another, rather smaller 

 specimen from Glastonbury the bridge is complete.

The femur of P. crispus, like the wing-bones, is both 

 longer and stouter than that of P. onocrotalus. Most of the 

 fossil specimens are intermediate in size between the two, 

 but nearer to P. crispus. One imperfect specimen seems to 

 have been fully as large as the femur of P. crispus.
