Neomenia (Solcnopus) in the British Seas. 165 



I cannot recall to mind with certainty other localities, I have 

 undoubtedly met with it in the Shetland seas. Last year I also 

 dredged it in the neighbourhood of Bergen, Norway, whence 

 also Koren's and Danielssen's specimens came. The genus 

 and species must in justice bear the name bestowed upon 

 it by Tullberg, who published an accurate description, illus- 

 trated by two plates of figures of the animal and its anatomy, 

 in 1875, at a time when M. Sars had only given the MS. 

 name. The synonymy of the British species will be : — 



Subclass OPISTHOBRANCHIATA, Milne-Edwards, 1848. 



Order Tjelobeanchiata, Koren and Danielssen. 



Genus Neomenia, Tullberg, 1875. 

 ( = Solenopus (Sars, MS.), Koren and Danielssen, 1878.)

It will be seen from Koren and Danielssen's paper that they 

 regard this curious animal as a mollusk, though so much 

 differing from previously known mollusks that it could not 

 be included in any of the established orders. It may be in- 

 teresting if I add here for comparison Tullberg's concluding 

 remarks, after he has previously gone carefully into the 

 anatomy ; he says : — 



" As regards the systematic position of this curious animal, 

 some few remarks offer themselves ; but it seems safer to defer 

 all detailed discussion on this subject until mure complete
