 Valvulina parisiensis Parker, Jones, and H. B. Brady, Ann. Mag. Nat. Hist., 



ser. 3, vol. 16, 1865, pp. 29, 35, pi. 1, fig. 26. 



Specimens occur at several stations varying in depth from 80 to 

 554 fathoms (146 to 1,012 meters), with bottom temperatures from 

 44.3° to 59.° F. (6.8° C. to 15° C). The specimens are of the slender 

 orm figured by Brady (pi. 48, figs. 17, 18), but specimens also occur 

 with very rough exterior like those on plate 48, figures 14 to 16. 

 There do not seem to be any connecting variations between these two 

 forms as far as the material available shows.
