and the femur and metatarsus are proportionately stouter. 

 Also, there is often a transverse depression on the anterior 

 surface of the metatarsus at the base of the fourth trochlea, 

 which seems to imply some peculiar habit/'' The skull is 

 shorter and flatter than that of E. crassa, and usually the 

 temporal fossa3 are deeper. 



Genus ANOMALOPTEEYX. 



In the femur the head is moderate in length and the neck 

 is well marked. The internal trochanterial surface is slightly 

 concave. The shaft is slender, and slightly curved longitudi- 

 nally on the anterior surface ; the linea aspera indistinct. The 

 popliteal depression is long, and very shallow ; the two tube- 

 rosities are but slightly developed. 



The length of the tibia is from 12 to 13 times its width in 

 the middle. The shaft is straight, and the antero-outer sur- 

 face slightly convex. The disial extremity is moderately 

 expanded inward ; the extensor bridge and tubercle are 

 directed above the outer condyle. 



The length of the metatarsus is from 5 to 6 times its width 

 in the middle. The proximal articular surface has its inner 

 mai'gin fiat or concave. The proximal interosteal foramina 

 open separately on the anterior surface, or into a shallow 

 depression. Usually the troehlege do not diverge so strongly 

 as in Mcgalapterijx, but this differs iii different species. The 

 second trochlea is not so long as in Meionornis, and its base is 

 not so broad as in Megalapteryx. Usually there is a depres- 

 sion at the base of the anterior surface of the third trochlea, 

 but this sometimes occurs also in Meionornis. 



Anomalopteryx fortis. 

 Anomalopteryx fortis, Hutton. 



The bones belonging to this species were four metatarsi, 

 two tibiae, five femora, a sternum, and a pelvis. Of the meta- 

 tarsi, the largest has a length of Sin. and a mid-width of 

 l-4in. ; the smallest is 7 -Sin. long, with a mid- width of l-3in. 

 In both of them the proximal width was 2'3in., and the distal 

 width 3in. 



Of the tibice, the largest was 16-5in. in length, l-3in. in width 

 at the middle of the shaft, and 2Tin. at the distal end. The 

 smallest was 15-8in. long, with a mid- width of l-3in. and 

 a distal width of 2in. 



Of i\iQ femora, the largest was 10-2in. long and the smallest 

 was 9-6in. ; in both the mid-width was l-3in. and the distal 

 width 3 -Sin. 



This occurs also in Anomalopteryx fortis.
