The National Museum owes to Col. A. ©. Bailward a most 
interesting collection of small mammals from Persia and Armenia, 
obtained during the past summer on his way home from India to 
England. Before starting he applied to the Society’s Secretary 
for advice on the subject, and Dr. Mitchell suggested his taking 
with him someone trained to collect mammals and birds. By 
good fortune Mr. R. B. Woosnam, one of our ablest collectors, 
who had already done good work in South Africa, was able to go 
with Col. Bailward, and the specimens now described were all 
trapped and skinned by him. 
Considering that the expedition was primarily a shooting-trip, 
that it never stayed more than a day or two in any place, 
and that the party rode something like 20 or 30 miles every 
day, the number of mammals obtained—about 70—is a credit to 
Mr. Woosnam, who also collected about 380 birds. 
About 31 species are represented in the Mammal collection, 
of which I have described five as new. Of these by far the 
most interesting is the beautiful large-eared mouse described as 
Calomyscus bailwardi, which forms a new genus entirely unlike 
anything hitherto known from the Old World, but allied to the 
North-American Peromyscus. 
Col. Bailward’s party entered Persia at the head of the Persian 
Gulf, beginning work at Ahwaz, on the Karun River. From 
there they travelled north-eastward across the Bachtiari mountains 
to Isfahan, and it was in this region that the majority of the 
novelties were obtained. From Isfahan they went westwards to 
Kermanshah, and thence by way of Lake Van, Erzeroum, and 
Baibort to Trebizond. 
While the Armenian specimens obtained during the trip are 
most valuable, their interest is dwarfed by that of the series from 
Persia, for from the region travelled by Col. Bailward the only 
mammals that have ever been collected were those obtained in 
1870-72 by the late Dr. W. T. Blanford, and described in his 
work on Kastern Persiat, the few collected and described by 
de Filippi§, and a small series obtained in 1902 by Mr. H. F. 
Witherby. From the character of the present collection it is

appears here; but since the names and preliminary diagnoses were published in the 
‘Abstract,’ such species are distinguished by the name being underlined.—Ep ITOR. |
