joint, In the Phyllostomide (as well as in Natalus and Rhyn- 
chonycteris) the calcar of the calcaneum was placed in axial line 
with that of the bone last named. In other families the calcar 
was adjoined to the calcaneum at the outer side and near the 
proximal end. The astragalus and calcaneum were nearly of the 
same size in most forms, the calcaneum being the larger. In the 
aberrant form Rhynchonycteris the astragalus was nearly twice 
the length of the calcaneum. I have appended a few diagram- 
matic sketches of the tarsus. 
he method employed in studying the tarsus consisted in re- 
moving all the soft parts of the foot, immersing in absolute alco- 
hol, transferring to oil of cloves and mounting on a glass slide. A 
low power of the microscope resolves all the essential structures.

RANGE OF THE AMERICAN Brson.—Late issues of the St. Paul 
Pioneer Press report : “Reliable cowboys just arrived in Miles City, 
Mont., report that at the Lower Musselshell round-up they saw a 
fresh trail of about 100 buffalo on the head of the Big Porcupine 
last week, and had seen twelve head a few days before. They 
killed one out of the twelve. The number of wild animals on the 
North Yellowstone ranges have proved not only a source of an- 
noyance to herd owners, but also of great damage to these newly 
stocked ranges. Round-up parties, in scouring those districts this 
spring, complain of the great number of calves killed and crip- 
pled by wolves and other wild animals. On Custer creek calwes 
were found that suffered from torn and bitten backs, which the 
boys attributed to the attacks of wildcats. Had the calves been
