SECRETARY'S REPORT 27 



After attending the Tenth Pacific Science Congress in Honolulu, 

 Dr. Leonard P. Schultz, curator of fishes, spent a few days in Septem- 

 ber on the island of Hawaii, where he made ichthyological observa- 

 tions of the offshore waters. He was impressed by the paucity of reef 

 fishes here in comparison with similar areas in the Pacific. 



In May and June Dr. J. A. F. Garrick, research associate in the 

 division of fishes, spent a week in the Bahamas at the invitation of 

 the International Oceanographic Foundation examining sharks dur- 

 ing a cooperative operation with the anglers in the Grand Bahama 

 Bluefin Tuna Tournament. Several sharks were taken, including an 

 adult of Carcharhinus springeH, which is of considerable interest be- 

 cause presently only juveniles of this species are available in museum 

 collections. A complete set of measurements and vertebral counts 

 were made on this and other specimens. 



In September and October Dr. J. F. Gates Clarke, curator of in- 

 sects, after attending the Tenth Pacific Science Congress in Honolulu, 

 conducted entomological field work in the South Pacific. Although it 

 proved impossible for Dr. Clarke to reach his principal objective, the 

 island of Rapa, because of adverse weather conditions, he made col- 

 lections of insects and other arthropods on the islands of Tahiti and 

 Huahine. In the material thus acquired, there seem to be many species 

 of Microlepidoptera which are new to the national collections and 

 some of which are doubtless undescribed. 



In August William D. Field, associate curator of insects, spent 2 

 weeks in the Great Smoky Mountains National Park primarily to 

 obtain specimens of the genus Rhopalocera. Forty species of butter- 

 flies were collected, of which several were unusual and rare, including 

 Speyeria diana and Lerodea neamathla. At the close of the fiscal year 

 Mr. Field was engaged in field work in Maine, collecting specimens 

 of Rhopalocera for the Museum and conferring with several local 

 collectors with regard to future contributions to the Smithsonian's 

 entomological materials. 



Dr. Oliver S. Flint, Jr., associate curator of insects, made a suc- 

 cessful collecting trip to Puerto Rico in August. As a result, the Mu- 

 seum collections now possess the immature stages of all species of 

 caddisflies known to occur on the island. In addition, the lengths of 

 the adult series were increased and several species previously unknown 

 were collected. The trichopteran material, which contains at least 

 2 new genera and over 12 new species, will be studied and reported 

 upon. A considerable collection of Odonata, both adults and naiads, 

 was made. 



At the end of the fiscal year. Dr. Donald F. Squires, associate curator 

 of marine invertebrates, and Thomas G. Baker, of the office of exhibits, 

 were still engaged in field work in New Caledonia. The Smithsonian
