 Serpulella vagans Eimer and Fickert, Zeitschr. wiss. Zool., vol. 65, 1899, p. 674. 



Description. — Test typically adherent, consisting of an oval-elon- 

 gate proloculum and a long irregularly winding tube of rather uni- 

 form diameter, unbranched, wall composed of sand grains of small 

 size and united by a reddish-brown cement often in considerable 

 amount, surface rather smooth, color 

 reddish-brown, the proloculum often 

 darker than the tubular portion. 



Diameter 0.05-0.2 mm., length 1 mm. 

 or more. 



Distribution. — This species occurred 

 at four Cliallenger stations and at eight 

 stations in the Albatross and Nero ma- 

 terial. These are well scattered in the 

 region west of longitude 150° W. and 

 south of latitude 40° N. Most of the 

 stations are over 1,500 fathoms, but 

 it has been noted in shallower water 

 off Japan, Albatross stations D4949, in 

 1 10 fathoms, D4957in 437 fathoms. It 

 occurred near the Hawaiian Islands, H2922 in 268 fathoms. The 

 deepest record for this species in the North Pacific is at Albatross 

 station H4014, 3,800 fathoms, attached to Hyperammina friabilis.

 Webbinella Rhumbler (part), Arch. Protistk., vol. 3, 1903, p. 229. 



Description. — Test adherent, composed of an oval proloculum with 

 a tubular chamber of variable length but of nearly uniform diameter, 

 the open end serving as the aperture; wall finely arenaceous but with 

 an excess of cement, proloculum without a definite floor. 



The generic name of this species following should be that proposed 

 by Eimer and Fickert. Webbina as used by Brady is not at all the
