vores, and monkeys, will be included in the final checklist of mam- 

 mals. Bats collected by Research Associate Hoogstraal in Africa 

 form the nucleus of the report on which recently appointed Assistant 

 Curator Karl Koopman is currently engaged. 



Division of Birds. Reports on recent collections from Peru 

 and from Colombia, which occupied Curator Emmet R. Blake, 

 have already resulted in the publication of the descriptions of 

 several new forms and a faunal paper on the birds of Cerro Maca- 

 rena, Eastern Colombia (see page 105). In collaboration with 

 Gunnar Hoy of Argentina he prepared a paper on the birds of 

 northern Argentina. Associate Curator Traylor continued work 

 on his checklist of Angola birds and on the Egyptian birds that 

 are hosts to arthropod-borne diseases. Associate Ellen T. Smith 

 completed a revision of a South American parrot. Chief Curator 

 Austin L. Rand investigated some correlations in wing size and 

 body weight of birds, nest structure and ornamentation in nut- 

 hatches, and late records of a supposedly extinct Philippine hang- 

 ing parrot. In the course of studies on recent Philippine collections 

 from Associate Rabor a new species of babbler in northern Luzon 

 was discovered. Chief Curator Rand has co-authored a book-length 

 manuscript on our midwestern seasons that has been accepted by 

 a New York publisher. 



Division of Amphibians and Reptiles. Curator Inger (assisted 

 by a grant from the National Science Foundation) is continuing a 

 study of the reptiles and amphibians of Borneo. With Assistant 

 Hymen Marx he is studying the food habits of amphibians of the 

 Belgian Congo and has completed a revision of a genus of snakes. 



Division of Fishes. Taxonomic studies of the marine fishes 

 of the Gulf of Mexico, Caribbean Sea, and the Atlantic Ocean 

 occupied Curator Woods, who published a short paper describing 

 a new species (see page 106). Associate Marion Grey carried on 

 her survey of the fish fauna found below a depth of 900 meters, 

 completed the final report on the Family Gonostomatidae for 

 Fishes of the Western North Atlantic (a series of volumes published 

 by Sears Foundation), and published several short papers including 

 descriptions of three new genera (see page 105). 



Division of Insects. Curator Wenzel's monograph on the 

 genus Margarinotus (histerid beetles) has been delayed while await- 

 ing receipt of critical material from Europe. However he has been 

 studying an exceptional collection of histerid beetles that live with 

 army ants. In this remarkable collection, which was made in Pan- 

 ama by Carl Rettenmeyer (University of Kansas) in connection 

 with studies on the biology of army ants, are a half dozen new
