OF SPECIAL INTEREST. 
The rare Rocky Mountain Sheep, and the Musk Ox in Case 
73. These are both rare in museums and the specimens are of 
the best. 
The Rocky Mountain Goat, in Case 69, is now fast becoming 
extinct and before many years will be unobtainable. The museum 
specimens are a male and female and most excellent specimens. 
The collection of plaster casts of food fishes in Case 71 is of 
great economic value, nearly every food fish being represented. 
The male and young elephant, on the raised platform in the cen- 
ter of the room, deserves careful observation. 
HALL 19. 
FAUNA OF THE GALAPAGOS ISLANDS. 
This room contains a collection of the Land-fauna of the 
Galapagos Islands, made during a visit of three months in 1891, 
by Prof. G. Baur, Clark University, now of the University of Chi- 
cago, and the late Mr. C. F. Adams, of Champaign, 111 . 
The Galapagos, well known through Darwin’s visit in 1835, 
are placed on the equator, about 600 miles west of Ecuador, to 
which state they belong. 
The most peculiar animals are the gigantic land-tortoises, 
which formerly were found in great numbers on nearly all the 
islands, but which to-day are restricted to two or three. The larg- 
est tortoise ever taken away from the Islands was secured on Al- 
bemarle and is on exhibition. Very characteristic are also two 
large genera of Iguanas, only found there, oneAm^fyr/iync/ius 
reaching a length of four feet, found on the sea-shore, and another, 
Conolophus^ found inland. Of Mammals only a bat and a small 
rodent is found, which are both peculiar to the Galapagos. 
Of the greatest interest, however, is the fact that each or 
nearly each island contains a peculiar fauna; but all these faunas 
are very closely related to each other, leaving no doubt that all 
these islands formerly consisted of one large island, which at a
