 from houses at Fort Reed, March, April and May. ' 



Periplaneta australasiae (Fabr.) Burm. Several young of 

 this species were taken at Ft. Reed during March, April and May. 

 This cosmopolitan species was first sent to me from Green Cove 

 Spring, Florida, by Mrs. Mary Treat, under the name of '* the Flor- 

 ida cockroach," and she reports that it frequently occurs in the 

 pitchers of Sarracenia, 1 and has been extremely abundant in Florida 

 for eighteen years, the torment of housekeepers. Yet it has never 

 before fallen into my hands, nor has it been hitherto recorded from 

 the United States. A single specimen in the collection of Dr. Har- 

 ris is marked " introduced; in ships from China."

List of Mammals found in the Vicinity of Grand River, 

 D. T. By W. J. Hoffman, M. D., late U. S. Army.

 lished May 20, 1870. It is situated on the western bank of the 

 Missouri River, one hundred and eight miles, by land, south of the 

 present terminus of the Northern Pacific Railroad,, and three hun- 

 dred and seventy miles north of Yankton. The valley of the Mis- 

 souri was well timbered in this vicinity prior to 1870, but since that 

 time the groves of cottonwood and oak have been gradually cut away, 

 affording but scanty shelter for many animals seeking them dur- 

 ing the cold season. Grand River, Oak Creek, and several smaller 

 streams emptying into the Missouri from the west, are often nearly 

 dry courses during the summer; but as we ascend to the distance of 

 fifty or sixty miles, we find them containing a greater amount of 

 water than nearer the mouth, and running through broad, well- 

 timbered valleys. At such localities many of the larger mammals
