FORAMIXIFERA OF THE ATLANTIC OCEAN. 51 



Distribution. — Egger described this species from a single specimen 

 obtained off the Cape Verde Islands in 69 meters. Nothing further 

 is known of the species. 



PROTEONINA AMBLYSTOMA Rhumbler. 



Proteonina ainblystoma Rhumbler, Foram. Planlcton-Exped., pt. 1, lull, pi. 2, 

 fig. 6; pt. 2, 1913, p. 377. 



Descnption. — Test free, elongate, subcyhnchical, main porhnu or 

 body of the test of about the same diameter as the neck; single 

 chambered, body portion composed of small irregular sand grains; 

 neck portion of larger grains more nearly uniform in size, apertural 

 end nearly as wide as the body of the test. 



Length, 0.576 mm.; breadth, 0.234 mm. 



Distrihution. — Rhumbler describes this species from a single speci- 

 men from off the Hebrides in 2,275 meters. The question may arise 

 at once whether this single specimen may not be an abnormal indi- 

 vidual of some already described species. It is noted here as a mat- 

 ter of record. I have seen no material referable to it. 



Genus LAGENAMMINA Rhumbler. 1911. 



Lagenammina Rhumbler (type, L. lagitnada Rhumbler), Foram. Plankton- 

 Exped., pt. 1, 1911, pp. 92, 111; pt. 2, 1913, p. 374. 



Description. — Test free, bottle shaped, with a pseudochitinous sub- 

 layer on which are laid quite thickly, but roughly, small foreign 

 bodies. The presence of this sublayer distinguishes this genus from 

 Proteonina, which does not have such a layer. 



LAGENAMMINA LAGUNCULA Rhumbler. 



Plate 19, fig. 8. 



Lagenammina lagunciila Rhumbler, Foram. Planlcton-Exped., pt. 1, 1911, pp. 92, 

 111, pi. 1, fig. 4; pt. 2, 1913, p. 375. 



Description. — Test free, bottle shaped, pouch of the bottle oval, 

 stretching out into a slender neck at the broader pole, which is half 

 as long as the body part. The thin under layer shows through the 

 interstices between the outer granules with a yellowish color. 



Length, 160-170^. 



Distribution. — This species was described by Rhumbler from two 

 North Atlantic stations in 1,524 and 2,400 meters. 



Genus PILULINA W. B. Carpenter, 1870.

Description. — Test free, globular or ovate, consisting of a single 

 undivided chamber; wall composed of felted sponge spicules and a 

 sHght amount of fine sand without cement, aperture elongate, with 

 a somewhat depressed area about it.
