ADDITIONAL MAMMAL NOTES. 
BY T. VAN HYNING. 
In the proceedings t>f the Iowa Academy of Sciences for 1910 appears 
“a preliminary annotated catalogue of the recent mammals of Iowa,” 
by T. VanHyning and Frank C. Pellett. The design in publishing that 
catalogue was for the purpose of obtaining more complete data for a 
monograph. It is now very gratifying to add the following notes as 
the results: 
The following species were given in that catalogue as only probably 
occurring in the state. They are now established as belonging to our 
Iowa fauna: 
Number 9 of the catalogue, Canada Porcupine. In about 1908 “some 
hounds in the same section,” Allamakee County, “were badly stuck up 
by porcupine quills, which had to be pulled from their mouths. Last 
summer, on French Creek, Allamakee County, I saw some scrub Hem- 
locks freshly cut and gnawed by porcupines.” Geo. H. Berry, Cedar 
Rapids, Iowa., April 8, 1913. 
Number 17. Lemming Mouse, or Cooper’s Mouse. “I have recently 
taken a fine specimen of synaptomys cooperi on the reservation right near 
the laboratory.” Prof. Thaddeus Surber, U. S. Biological Station, Fain 
port, Iowa, Feb. 16, 1912. 
Number 24. Western Harvest Mouse. “It may interest you to know 
that the harvest mouse, Ueithrodonomys dychei, is quite common here.” 
Prof. Thaddeus Surber, U. S. Biological Station, Fairporf, Iowa, Febru- 
ary 16, 1912. 
Number 75. Pekan: Fisher. “Plenty of coons and some fishers ran 
wild in the timber.” John G. Smith, in Register and Farmer, Algona, 
Iowa, February 11. 
The following were noted in the catalogue as extinct in Iowa, but may 
now be considered as living in the state : 
Number 69. American Otter. “M. W. Conwell, a local furrier, dis- 
plays the skin of a" large otter recently trapped on the Des Moines River, 
near Harvey, ten miles east of Knoxville. The pelt is in fine condition 
from the standpoint of the furrier, and is 5 feet 9 inches from tip to tip. 
The animal was trapped by John Morgan. About a week ago one of 
Mr. Morgan’s traps .was sprung by an otter .which gnawed its leg off 
and escaped.” Knoxville, Iowa., February 24, 1913.
