NOTES ON MYSIDACEAN CRUSTACEANS 



OF THE GENUS LOP1IOGASTER 



IN THE U.S. NATIONAL MUSEUM 



By O. S. Tattersall, D. Sc. 



The manuscript of U.S. National Museum Bulletin 201, "Review 

 of the Mysidacea of the United States National Museum," by W. M. 

 Tattersall, was completed in 1939 but, owing; to wartime restrictions, 

 was not published until Oct. 4, 1951. During the intervening 12 

 years, literature containing references relevant to Tattcrsall's work 

 appeared and some systematic changes were introduced. The most 

 important of these were contained in two beautiful "Dana Reports" 

 (Xos. 19, 23) on the Lophogastrida collected by the Dana Expeditions 

 (Fage, 1941; 1942). Of these two, only the second deals with the 

 genus Lophogaster. 



Interchange of literature at the time was impossible and, although 

 Tattersall, who died in 1943, was aware that a 1940 publication by 

 Fage contained preliminary diagnoses of certain new species of the 

 genus Lophogaster, he never saw it or the subsequent Dana Reports. 



When literature once more became available, it was evident that 

 many amendments would have to be made to Tattcrsall's Bulletin 

 201 in order to bring it up to date with the time of its publication.
