Affinities. — This species is admirably illustrated by Smitt whose 



figures are perfectly exact. Our photographs only indicate the size 



at our usual X 20 enlargements. 



The ovicelled zooecia are wider than the others; their presence 



occasions an enlargement of the segments, which present thus a sort 



of very characteristic nodosity. 



Smitt was in error in identifying his specimens with Salicornaria 



tenuirostris Busk, 1852, as they differ in the much more slender segments 



swelling in places, in the enlarged form of the ovicelled zooecia, in 



the lozenge-shaped and nonrhomboidal form of the avicularia, in the 



presence of a canalicule in the avicularium, and in a much smaller 



aperture (0.08 and not 0.13). We have therefore given another 



name to this charming species. It is regrettable that it did not 



preserve its chitinous appendages. 



Occurrence. — Albatross Station D. 2388, Gulf of Mexico; 29° 24'

Holotype.—C&t. No. 7472, U.S.N.M 



CELLARIA SINUOSA Hassall, 1842 



This is the first time that this beautiful species, very common in 

 Europe, has been found in the vicinity of the American coasts. We 

 do not believe that we are deceived in our determination. 



Occurrence. — Albatross Station D. 2004. Atlantic Ocean, east of 

 Cape Hatteras, 37° 19' 45" N.; 74° 26' 06" W.; 102 fms.; green
