306 PEOFESSOE W. K. PAEKEE ON THE 



The epipterygoid process {e.pg) is a mere auriform projection, as in the Crane (fig. 6) ; 

 the shaft of the bone is carinate, and the palatine end bilobate. 



The palatines (figs. 2 & b,pa) are higher, where they ascend to the pars plana, than 

 broad ; they are elegantly bowed out behind, and, indeed, have altogether au undulating 

 outline. Every curve and ridge and process corresponds with what is seen in Anthro- 

 po'ides (fig. 6) : in each case these bones diverge to join the pterygoids, arch outwards 

 external to the interpalatine and ethmo-palatine spurs {i.'pa, e.pa), converge where they 

 form a floor to the maxillo-palatine plates {mx.p), and are again gently arched outwards 

 where they carry the alinasal cartilages {al. n) ; in front they have been aflected by the 

 intense ossification of the entire beak. 



The solid dentary angle of the prsemaxillary (d.px) has become completely fused with 

 the outer part of the maxillary (m>f) ; and its jugal process has coalesced largely with 

 the jugal and quadrato-jugals {j, q.J) ; their line of junction can, however, be seen. The 

 maxillo-palatine plates {mx.p) are short, broad, and ear-shaped — quite normal for a Plu- 

 vialine bird in general, or for a Gruine bird in particular ; their distance from each 

 other, as compared with those of the Crane (fig. 6), depends upon the size of the 

 intervening vomer, with the bevelled shoulders of which they articulate, as in many of 

 the lower types of South- American Passerinse. 



The quadrate is that of a Crane ; the upper and lower otic processes are divergent 

 and very distinct, wholly unlike those of a Fowl, in which the prootic facet (lower 

 head) is a mere patch of articular cartilage inside the single rounded head or upper 

 process. 



The free fore-turned " pedicle," or orbital process, is true to the Gruine type, being 

 broad-ended and ear-shaped. 



The mandible has some Gallinaceous characters, which might beguile a hasty 

 observer : the ramus is high and has a large double fenestra ; the symphysis is short 

 and strong ; and the posterior and internal angular processes are longer than is normal 

 in a Pluvialine bird ; they thus approach those of a Fowl. 



APPENDIX TO THE DESCRIPTION OF THE ^GITHOGNATH^. 



1. The Skull op Anthropoides stanleyanus. 



I have already described the palate of this species with that of Thimcorus, and need 

 now only refer the reader again to the figures of these two types, so diverse in outward 

 form, so distinct from each other in mere detail, and yet on the whole so incontestably 

 related and alike in all essentials. 



The mere size and the breadth or narrowness of the various bones are things of but 

 little importance in the presence of so much that is harmonious.
