PROTEONINA OVATA, new species. 



Description. — Test free, ovate in side view, nearly circular in end 

 view, wall thick, composed of neatly cemented and fairly large sand 

 grains, apertural end abruptly contracted to form a short, tapering 

 neck with the very small aperture at its extremity; color light 

 yellowish or brownish gray; fairly large 



Length about 1.25 mm.; diameter about 0.6 mm. 



Distribution. — Specimens of this species have been seen in material 

 from but two stations, Albatross H3007, in 323 fathoms, and Nero 

 station 2071, in 271 fathoms, both near the Hawaiian Islands. 



FlG. 43.— PROTEONINA OVATA. X 50. a, FRONT VIEW; b, APERTURAL VIEW. 



Type-specimen.— €at. No. 8264, U.S.N.M., from Nero station 2071. 



The species is a fairly large one. The form, abrupt contraction 

 of the neck with the very small aperture, will at once distinguish this 

 from other described species. 



Genus PILULINA W. B. Carpenter.

 Objects Deep-Sea Dredging [1870], p. 5.— H. B. Brady, Rep. Vo'y. Challenger, 

 Zoology, vol. 9, 1884, p.- 244.— Rhumbler, Arch. Protistk., vol. 3, 1903, 

 p. 249. 



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

 undivided chamber, wall composed of felted sponge spicules and a 

 slight amount of fine sand without cement, aperture elongate, with a 

 somewhat depressed area about it. 



A single species was described by Carpenter from the North Atlantic. 

 A new species has been found in material dredged by the fisheries 

 steamer Albatross north of Japan differing in certain characters from 

 the species described by Carpenter. The wall of these species is 

 rather unique, as no cement seems to be used, the long spicules being 

 felted together into a thin wall.
