REPORT ON THE DEPARTMENT OF INVERTEBRATES. 135 



furnished by the Museum and Fish Commission, both of which are bene- 

 fited by his work. A portion of his collection, received before the close 

 of the year, is acknowledged above. Ensign W. E. Safford. U. S.Navy, 

 who was detailed in 1883 for instruction in natural history at the 

 National Museum, arrived in San Francisco, California, during last 

 spring from a long cruise on the U. S. S. Mohican, which sailed from the 

 Atlantic coast about a year before. A collection received from him in 

 June indicates that the many rare opportunities afforded him for ob- 

 taining specimens were not neglected, and the surface towings he ob- 

 tained are very rich in interesting forms. Lieuts. W. M. Wood and A. 

 Baker, U. S. Navy, who were also formerly in the service of the Com- 

 mission, have made collections during their cruises of the past year, 

 which have not yet been received. Lieut. Commader H. E. Nichols, 

 U. S. Navy, of the steamer Pinta, has continued his collecting on the 

 southern Alaskan coast, and Dr. Ferebee, TJ. S. Navy, of the U. S. S. 

 Trenton, has sent in a number of specimens which he obtained in Corea 

 and China.
