FORAMINIFERA OF NORTH PACIFIC OCEAN. 61 



Genus LINGULINA d'Orbigny, 1826. 



Lingulina d'Orbigny (type L. carinata d'Orbigny), Ann. Sci. Nat., vol. 7, 1826, 

 p. 256.— H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 517. 



Description. — Test compressed, chambers arranged in a linear 

 series, usually closely set; aperture usually elongate, corresponding 

 to the form of the chamber. 



This genus seems to be less clearly defined than many of the genera 

 established by d'Orbigny. It is closely related to Nodosaria, differ- 

 ing from this genus only in the compressed character and the conse- 

 quent changes in the aperture. 



Species of this genus are few in number but have a wide range. It 

 is most common as a fossil in the Miocene.

Description. — Test compressed, chambers in a linear series, early 

 ones short and broad, later ones usually hyaline, edges nearly acute, 

 surface smooth; aperture an elongated, simple ellipse without a defi- 

 nite neck or radiate openings. 



Length up to 3 mm. 



Distribution. — In the North Pacific, Brady records this species 

 from the Challenger dredgings, off the Honolulu coral reefs, Hawaiian 

 Islands, in 40 fathoms. Bagg records it as rare off the same islands, 

 Albatross station 4508, in 495 fathoms. This is the specimen figured 

 here. 



Many forms have been figured as belonging to this species which it 

 does not seem should be placed here, as their characters are so unlike 

 the type of d'Orbigny's species.
