PART 1 GARTH : PACIFIC OXYRHYNCHA 45 



with Dr. Yanez that the ultimate status of E. latreillei, whether as 

 one species or more than one, should rest with persons having access to 

 abundant fresh material, it is his hope that such a final study will be 

 attempted by someone as thoroughly versed in the literature as, and 

 possessed of an array of comparative material not less extensive than 

 that available to, Miers, Lagerberg, or Rathbun. 



The excellent review of the species by Lagerberg (1905) should 

 be supplemented by the discussion of Stebbing (1914), who corrects 

 the spelling of an otherwise impeccable synonymy while noting that 

 Lagerberg erroneously credited H. Milne Edwards, instead of Guerin, 

 with the Crustacea of the Coquille. In an earlier paper Stebbing (1900) 

 expressed regret that Miers, writing in 1881 and 1886, failed to include 

 reference to Targioni-Tozzetti (1877), on whose work his opinion 

 would have been invaluable. Stebbing also presents convincing evidence 

 to the effect that Dana (1855) may have relied too strongly on his 

 memory in assigning fig. d of plate 3 to Eurypodius latreillei in the 

 explanation of plates after the original drawings had been destroyed by 

 fire. 



Other items gleaned from a review of the historical treatment ac- 

 corded the species include an early reference to the genus as occurring in 

 the Indian Ocean (H. Milne Edwards, 1834), whereas the only species 

 known at that time was Eurypodius latreillei of the Falkland Islands 

 (Philippi, 1894, p. 266). This may account for Smith's (1869) refer- 

 ence to an East Indian locality for the species, for many a New Eng- 

 lander of his day held similarly vague ideas concerning the geographical 

 position of "les lies Malouines." 



The collections of the Velero III are drawn from a relatively nar- 

 row sector of the species range and do not exhibit the extremes of varia- 

 tion shown in series from more widely separated localities. The collec- 

 tions of the Hamburg Museum from north Chile and those of the Lund 

 University Chile Expedition from south Chile are therefore opportunely 

 come by. While the possibility of correlating intraspecific variation with 

 geographical distribution is an intriguing one, it is not proposed here to 

 alter the present systematic arrangement. The contribution made by 

 the Velero III collections is rather to define with greater precision the 

 northern limit of range of the species on the Pacific coast of South 

 America, substituting Independencia Bay for the more general designa- 

 tion "Peru" that has obtained since the voyage of the Bonite (Eydoux 

 and Souleyet, 1842-43). 



The accompanying illustration of the male first pleopod (Plate B, 

 fig. 1) supports the withdrawal by Balss (1929) of Eurypodius from
