the ulna shows a rudimental olecranon ; it is a little longer and broader than the radius. 

 There are no distinct carpals : the metacarpus consists of a coalescence of three hones, the 

 middle of which supports a single phalanx. In the pelvis the slender pubis and broader 

 ischium extend backwards straight and almost parallel with the hinder half of the ilium. 

 The ilium and ischium join each other posteriorly and circumscribe the long ischiatic notch. 

 The pubis, confluent as usual with the ilium and ischium anteriorly, is free in the rest of its 

 extent. The femora have no pneumatic foramen, either at the fore or back part of the neck : 

 the medullary canal perforates the middle of the back part of the shaft : the intermuscular 

 ridges which extend to the fore part of each condyle begin to diverge immediately below the 

 great trochanter. The rotular process of the tibia developes a strong procuemial and ecto- 

 cnemial ridge : the fibular linea aspera extends nearly to the distal end of the bone. The 

 fibula remains distinct. There is no osseous bridge at the fore part of the distal end of the 

 tibia. The calcaneal process of the tarso-metatarsus is an elongated compressed ridge, with 

 a vascular perforation on each side leading to a single foramen at the anterior part, near the 

 proximal end of the bone ; a deep and wide excavation extends down the middle of the fore 

 part of the metatarse. The ungual or third phalanx of the inner toe is unusually elongated and 

 nearly straight ; the outer toe, though the shortest, has, as usual, five phalanges.

1358. The skeleton of the Emeu (Dromaius NOVCK Hollandice). 



There are 26 vertebrae between the skull and sacrum, of which the last eight support ribs : 

 of these the first three pairs are free ; the next three pairs are articulated by strong bony 

 hsemapophyses with the sternum ; thos^ of the seventh pair are long, but do not reach the 

 sternum ; the eighth and ninth pairs of ribs are free ; the ninth is attached to the sacrum. 

 There are 8 caudal vertebrae. The sternum is pointed posteriorly ; the anterior angles are 

 singularly developed and incurved. The clavicles or halves of the furculum are distinct from 

 each other and from the coracoids : they are short and slender bones, and do not reach the 

 sternum. Neither the ischia or pubic bones join the ilium or their fellows posteriorly.
