 Articulina nitida D'Orbigny, Ann. Sci. Nat., vol. 7, 1826, p. 300, No. 1; Modeles, 

 No. 22. 



Description. — Test with the early chambers milioline, forming but 

 a comparatively small part of the completed test, later chambers 

 arranged in a linear series, chambers usually longer than wide, the 

 lip flaring somewhat, nearly circular in cross section; wall with 

 comparatively few costae; aperture nearly circular, with a smooth, 

 flaring Up. 



Length, up to 2 mm. 



Distribution. — Apparently this species had not been definitely 

 recorded from the North Pacific. The only material I have had is 

 rather poor, from Nero station 2037, in 55 fathoms, off the Hawaiian 

 Islands, from Albatross station H4829 in the eastern Pacific, and from 

 Hongkong. In all cases the specimens were broken.

Vertebralina sagra Goes, Bull. Mus. Comp. Zool., vol. 29, 1896, p. 89. 



Description. — Test with the early chambers milioline, later ones, 

 usually two or three in a linear series, flattened, three or four or more 

 times as wide as thick, apertural end broadened, somewhat flaring, 

 curved, giving the appearance of several vertebrae, wall costate 

 longitudinallv; aperture narrowly elliptical, with a smooth projecting 

 lip. 



Length, up to about 1 mm. 



Distribution. — Brady records the species from the coral reefs off 

 Honolulu, Hawaiian Islands, in 40 fathoms. Neither Bagg nor 

 Goes record this species from the Pacific. I have had material from 

 Nero station 2071 in 271, fathoms, off the Hawaiian Islands, and 

 from Gaspar Straits, North Pacific Exploring Expedition, Captain 

 Kodgers. The species does not appear to be at all common, as it 

 is in the West Indies, for example. Most of the material I have had 

 was from deep water, however, and this may account for its apparent 

 scarcity, although it should be found in shore sands of the tropical 

 Pacific. 



There seems to be some confusion with regard to the development 

 of the species and many various forms have been assigned to it. 

 A study of it from typical localities should help to straighten out 

 these discrepancies.
