Loyenia Forbesi, Woods and Duncan. Plate IV. figs. 5-8. 



Syn. Hemipatagus Forbesi, Woods and Duncan. 



Not as figured in Etheridge, Quart. Journ. Geol. Soc. yoI. xxxi. 

 pi. xxi. fig. 8, but in Ann. and Mag. Nat. Hist. ser. 3, vol. xiv. 

 pi. Yi. fig. 3 e,f. 



Syn. Hemipatagus Woodsi, Etheridge, (a variety) var. Wooclsi. 

 Syn. Hemipatagus Forbesi, Laube.

 tagus forms an acute angle posteriorly, and just behind the madre-
