The heart of this \dnnL;- shag presents nothing of a x'cry

in so far as its geiier.al characters are concerned. 
As will he obser\ed from h'ig. 3, I Mate II. the lower bifurca- 
tion of the f]-aclica and the hrniichi are of ve-r\- simple construc- 
tion. The large terminal irachial half-wing meets neither 
anteriorly nor ])osteriorly, the interxal being more marked be- 
hind than it is in front, and this ring is i)rominentl\- raised and 
mdi\iduali/ed all roun.l. A IhssuIus has alreadv tormed. .X-

At this age, the lungs fill but a \ery small s])ace in the chest-

There is a rudiment;ir\ (//'<;/'/;/■(/-//; present, being in con- 
tact on its posterior surface with the two lobes of the liver and 
the large stomach. 
As is fref|uentl\- the case in birds, the /•;-/'/ '"/t I'f the liver 
is more th.an double the size of the left lolie, wiiile in the case 
of either of them the posterior margins are sh.arp and the an- 
terior ones rounded. The left lobe is concaxe on its dorsal 
aspect and comex \entrall\. The right lobe also is con\ex on 
its \enlral surface, Imt nearl\ llat dorsally. The twd lobes are 
in contact and slightb- o\erla]) in the me(lium line, while the 
two in fi-onl are f.aslnoiied to .admU of room for the \enli'icular 
portion of the heart.
