NO. 1246. MAMMALS OF VENEZUELA— ROBINSON AND LYON. 137 
On July Captain Robinson made a reconnoissance along- the rail- 
road to Caracas in .search of better collecting- ground, but saw only one 
place that looked at all promising, a station called Cucuruti, about 
halfway up the road. He spent a half da}' here on July 7, Init was 
unable to arrange for food or shelter. 
On July 11 he made a second reconnoissance, this time to San Julian, 
and tinding that the ground was favorable and that he could secure a 
vacant hut, he moved there on July 13 and remained until August 10. 
Mr. Lyon joined him on July 16, but was compelled by illness to 
return to La Guaira on July 22. He shortly after moved to Macuto, 
where he collected until August 10, in the meantime making- one 
excursion for bats to a cave near Peiia de Mora, on the La Guaira and 
Caracas Railroad, 9 miles l)elow Caracas and at an elevation of 2,295 
feet. 
The return steamer to New York was taken on August 13. 
In submitting the.se notes the writers wish to express their indebted- 
ness to Mr. Gerrit 8. Miller, jr., for much advice on technical points; 
to Dr. J. A. Alleii, of New York City, Mr. Witmer Stone, of Phila- 
delphia, and Mr. Outram Bangs, of Boston, for the examination of 
South American material in their possession; and to Mr. Oldlield 
Thomas, who compared several specimens with types in the British 
Museum. 
Owing- to his connection with the U. S. National Museum and facili- 
ties for comparisons and references, the descriptions of new species 
and the technical parts of this paper are entirely the work of the junior 
author, while the field notes have been almost exclusively compiled ])y 
Captain Robinson. 
Where specimens are listed by numbers in the following pages it 
should be observed that those specimens preceded by the letters " W. 
R." are in Captain Robinson's collection,^ while specimens unpreceded 
by letters belong- to the Museum collection. Measurements of speci- 
mens are in millimeters unless otherwise stated.
