﻿148 PROCEEDINGS OF THE NATIONAL MUSEUM vol. lOO 



These collections are included in this paper in order to complete 

 the listing of the Antarctic species possessed by the Museum. 



The geographical names used in this paper are in agreement with 

 that estimable publication "Sailing Directions for Antarctica" (U. S. 

 Hydrographic Office No. 138), and U. S. H. O. Chart No. 2562. Dr. 

 Gordon, in her most recent paper (1944), summarizes the distribution 

 of many species by "quadrants," based on the 90° sectors of the i^itarc- 

 tic, using a set of names not recognized by American geographers. 

 The Gauss, Victoria, Boss, and Weddell quadrants, are, I presume, 

 equivalent to the African, Australian, Pacific, and American quad- 

 rants of the National Geographic Society map. Yet she also mentions 

 (p. 16) the "Enderby" quadrant, which is evidently the same as the 

 Gauss quadrant. Perhaps it is unfair to mention this slight incon- 

 sistency in a work published during the war years, when it was im- 

 possible to send proofs to the author. However, the use of quadrants 

 in summarizing Antarctic distribution is unsatisfactory, since the 

 division is artificial. This is especially true of the Ross Sea area, a 

 natural geographical region bisected by the 180th meridian and thus 

 falling into two quadrants. It is probably best to use more general 

 terms, such as Kerguelen and Magellan districts, and Ross and 

 Weddell Sea areas, which in fact is Dr. Gordon's more usual practice. 



Family NYMPHONIDAE Wilson, 1878 



Genus NYMPHON J. C. Fabricius, 1794 



Nymphon Gordon, 1932b, pp. 26-36 ; 1944, pp. 17-22. 



Gordon's fine comprehensive keys to the Antarctic species of this 

 genus have greatly simplified the examination of Antarctic collections. 



In addition to the species formally listed below, the following, all 

 from South Georgia, are in the U. S. National Museum collections: 

 NyTnphon hiemale Hodgson, 2 females; Nymphon hrevicaudatuTn 

 Miers, 3 males, 4 females; Nymphon charcoti Bouvier, 3 females. 

 These species have all been reported previously from this locality.
