GENERAL NOTES. 



THE TRINIDAD OPOSSUM ON MARTINIQUE.* 



The large Trinidad opossum ( Didelphis marsupialis insuloris) has been 

 recorded by various authors from the West Indian islands Dominica, 

 Grenada, and St. Vincent, but there appears to be no published account 

 of the species on Martinique. In the collection of the United States 

 National Museum are three specimens of this opossum with records as 

 follows: Nos. 5860 and 5861, 9 and juv., "Martinique, Com. Perry," 

 catalogued in 1862; and No. 13,038, $, "Martinique, W. I., August, 

 1878, F. A. Ober." —.V. Hollister. 



THE MONA MONKEY ON THE ISLAND OF ST. KITTS.* 



There is, apparently, no published record of the Mona Monkey on the 

 island of St. Kitts, West Indies. In Dr. Glover M. Allen's recently pub- 

 lished "Mammals of the West Indies," the Green Guenon is recorded 

 from this island, as well as from Barbados, and the Mona is recorded 

 from Grenada. In the United States National Museum collection, in 

 addition to specimens of the Green Guenon, is a skin of the Mona 

 ( Lasiopyga mona) collected on St. Kitts in 1880 by Mr. Fred A. Ober.

TWO GENERA OF BATS NEW TO MIDDLE AMERICA. 

 In the recent collections of mammals made by E. A. Goldman in con- 

 nection with the Smithsonian Biological Survey of the Canal Zone, are 

 species of two S >uth American genera of hats not heretofore known from 

 Middle or North America. One is Dirias minor (Osgood) recently de- 

 scribed from Encontrados, Zulia, Venezuela, and represented in Gold- 

 man's collection by a single male specimen from Empire, Canal Zone, 

 where it was captured February 16, 1912. The other is Macrophyllum 

 macrophyllum (Wied) described from Brazil and of which two specimens 

 were collected in the ruins of the old city of Panama February 7, L912. 

 I am indebted to Mr. Gerrit S. .Miller, Jr.. for calling my attention to 

 these additions to the Panama fauna, early publication of w hich is desira- 

 ble in connection with other work now in progress.
