this specimen were found articulated together in the quarry, the ribs of one side 
in position, the remainder of the bones scattered around them, and some of the 
tail-bones weathered out on the surface. 
toth dorsal vertebra, and right femur and tibia. 
No. 339, from Bone Cabin Guarry, Wyo., supplied the 2zoth to 4oth caudal 
vertebre; No. 592, from the same locality, the metatarsals of the right hind 
foot, and a few toe-bones are supplied from other specimens. 
The remainder of the skeleton is modeled in plaster, the scapula, humerus, 
radius and ulna from the skeleton in the Yale Museum, the rest principally 
from specimens in our own collections. The modeling of the skull is based in 
part upon a smaller incomplete skull in the Yale Museum, but principally upon 
the complete skull of MJorosaurus shown in Case 42.

TWO NEW BIRD GROUPS.

duced on pages 71 and 77, more closely approach 
the Museum’s ideal of an exhibit illustrating the 
haunts and nesting-habits of birds than any which have here- 
tofore been prepared. 
Both are based upon careful field studies, by artist as well as 
by ornithologist, and both accurately portray not only the home- 
life of the species they represent, but also, through the use of a 
painted background, the character of the region in which the 
birds live. 
Aside from their beauty,- which renders them attractive to 
the most casual observer as well as to the ornithologist, these 
groups possess much scientific value. This is particularly true 
of the Flamingo group, in which the nesting-habits of this bird 
are for the first time properly shown. 
These two groups make important additions to the series 
already prepared through the generosity of several friends of 
the Museum, who have contributed to a fund designed for this 
purpose. 
By no means the least important feature of the Museum’s 
expedition to the Bahamas in search of material for the Flamingo
