EuPHAUSiA KROHNii (Brandt). 



1851. Thysanopoda krohnii, Brandt, Middendorff' s Sibirische Eeise, 



vol. ii., pt. 1, p. 127. 

 1863. Euphausia milllcri, Glaus, Zeitschr. wiss. Zool., vol. xiii., 



p. 444, pi. 28, figs. 29-31, pi. 29. 

 1885. E. pcllucida (part), Sars (not Dana), Challenger Schizopoda, 

 Eeports, vol. xiii., p. 75, pis. 11, 12. 

 Among various localities for this species Sars gives " South 

 of Cape of Good Hope." But for his identification of the 

 species with Dana's E. pellucida I may refer to my remarks 

 in Proc. Zool. Soc. London, for 1900, p. 538, and to those of 

 H. J. Hansen under the next reference, which leave it 

 doubtful what was the species actually taken south of the 

 Cape. 



1905. E. muUeri, Hansen, Bull. Mus. Oceanogr. Monaco, No. 42, 



In a preliminary discussion Hansen discards Dana's 

 E. pellucida as unrecognisable, and further says : " According 

 to the description and the figures of Sars, E. piellucida, 

 G. 0. S., is distinguished by possessing two pairs of lateral 

 denticles on the carapace, while only one pair or no denticle 

 at all is found in the other forms of the genus. But I have 

 four excellent species with two pairs of lateral denticles, each 

 of these species from a large number (more than twenty) 

 stations, and judging from the list of stations given by Sars 

 and from his enumerations of synonyms I am sure that he has 

 mixed together at least three of these species. Dana figures 

 E. pellucida as a very slender species with small eyes ; if his 

 figures be tolerably correct, none of my four species can be 

 referred to that form." 



1906. E. milllcri, Holt and Tattersall, Fisheries, Ireland, Sci. Invest., 



1904, V. [1906], p. 6. 

 1910. E. krohnii, Hansen, Schizopoda, Siboga Exp., pt. 37, p. 90. 



Euphausia lucens, Hansen. 

 1885. Euphausia splendens, Sars, Challenger Schizopoda, Eeports, 

 vol. xiii., p. 80, pi. 13, figs. 7-17. 

 " Off Cape of Good Hope." Sars himself doubtfully I'efers 

 this species to the form so named by Dana, and in Proc. 

 Zool. Soc, 1900, p. 539, I have dwelt on the difficulties of 

 identification.
