NEW ENGLAND ZOOLOGICAL CLUB 
NOTES. ON THE MAMMALS OF BLOCK ISLAND, 
RHODE ISLAND. 
BY OUTRAM BANGS. 
In August, 1899, I made a stay of about ten days on Block Island 
for the purpose of securing a series of the indigenous mammals 
of the island, but for one reason or another I never until now have 
published an account of the results of my trip. 
Block Island lies about nine miles directly out to sea off the coast 
of Rhode Island, and is about fourteen and a half miles from Mon- 
tauk Poimt, Long Island. It is under high cultivation, and is 
entirely without woods, or even trees, except for a few willows and 
poplars planted near some of the houses. ‘The island is composed 
of a series of low hills, of a gravelly soil, with innumerable little 
ponds in the valleys among them. 
Mammals were not at all common on the island, and, apart from 
the house mouse (Mus musculus musculus Linn.) and the Norway 
rat (Mus norvegicus norvegicus Erxl.), both of which have been 
established and occur in a feral state, I found but two species, a 
Microtus and a Peromyscus. Nowhere could I find traces of the 
work of the mole (Scalops), nor did Blarina, Sorex, nor Zapus, fall 
into any of the hundreds of traps with which I covered the island. 
All of these genera occur on the islands off the southern coast of 
Massachusetts, and I had expected to find some of them, at least, 
on Block Island. 
The Peromyscus of Block Island, as I have already stated in 
another paper,’ is like that of most of the other islands of the south-
