Report of the Director for ig22 7 



of Hawaiian trees" (Occasional Papers, Vol. VIII, No. 6) was issued 

 by the Museum. 



Elizabeth Wuist Brown, Research Associate in Botany, was a member 

 of the Marquesas party of the Bayard Dominick Expedition for the years 

 1920-21 and 1921-22. Her attention was given chiefly to investigation of 

 the cryptogamic flora. 



The time of Edwin H. Bryan, Jr., Assistant Entomologist, has been 

 given partly to the care and study of the collections of insects and partly 

 to general Museum duties. Considerable progress has been made in the 

 preparation of a paper on Hawaiian Diptera, which includes descriptions 

 of all species recorded in the Territory', and also on a card catalog of the 

 entomological literature in Honolulu. For collecting insects trips were 

 made to the Napali region on Kauai and to parts of Oahu. 



C. Montague Cooke, Jr., Malacologist, spent the first half of the year 

 at the Philadelphia Academy of Natural Sciences in dissecting specimens 

 of Endodontidae and Zonitidae, preparatory to the preparation of a mono- 

 graph on these families. In the Museum laboratory the most important 

 work accomplished was the cataloging of the Wilder collection of 48,291 

 specimens, one of the largest and most valuable collections of Oahuan 

 Achatinellidae. Field trips were made to the Waianae Mountains, Oahu, 

 and to the islands of Kauai, Maui and Molokai. Through the efforts of 

 Mr. Cooke much valuable shell material has been received during the year. 



Henry E. Crampton, Research Associate in Zoology, has continued 

 his investigation of the collections of Partula obtained in 1920 from Guam 

 and the Marianas Islands. The statistical analysis of the material has 

 been entirely completed, and substantial progress has been made in the 

 writing of a monograph. 



Charles H. Edmondson, Zoologist, has been engaged in the classifica- 

 tion and arrangement of the zoological material stored in the Museum 

 buildings. His field work during the year included collection trips to 

 Molokai and Fanning islands (pp. 6, 19) and investigations of marine 

 fauna at Kahana Bay, Kawailoa, and Waikiki on the island of Oahu. He 

 has arranged for exchanges of identified material with the Australian 

 Museum and the Zoological Survey of India. For the identification of 

 Hawaiian collections, he has enlisted the generous assistance of Dr. Her- 

 bert L. Clark of the Museum of Comparative Anatomy, Dr. Henry A. 

 Pilsbry of the Philadelphia Academy of Natural Science, Dr. A. A. Tread- 

 well of Vassar College, and also of Miss Mary J. Rathburn, Dr. Waldo L. 

 Schmitt, Clarence R. Shoemaker and Dr. Paul Bartsch of the National 

 Museum.
