FORAMINIFERA OF NORTH PACIFIC OCEAN. 27 



Distribution. — Type-specimens, Cat. No. 8534, U.S.N.M., from Tus- 

 carora station 23, lat. 21° 40' N.; long. 179° 20' E., in 1,964 fathoms. 



The ornamentation of this species is a peculiar one composed of the 

 prominent oval ring and the irregular broken costse of the rest of the 

 test.

 Lagena striato-areolata Sidebottom, Journ. Quekett Micr. Club, vol. 11, 1912, 



p. 390, pi. 15, fig. 27. 



Description. — Test flask-shaped, neck long and slender, upper por- 

 tion of test with four costa? becoming tubular or punctate below, in- 

 termediate portion composed of an irregular, generally hexagonal, 

 net-work. 



Length 0.5 mm. 



Distribution. — The single specimen, which compares very favorably 

 with the figure given by Sidebottom noted above, is from Nero station 

 172 in 2,086 fathoms, between the Hawaiian and Midway Islands.

Lagena torquata H. B. Brady, Quart. Journ. Micr. Sci., vol. 21, 1881, p. 62; 

 Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 469, pi. 58, fig. 41. 



Description. — Test flask-shaped, neck long and slender, surface of 

 test with a series of prominent primary longitudinal costse with punctse 

 or tubulations down the middle of each, between each pair of primary 

 costse secondary costse, imperforate, shorter and less prominent, and 

 transversely finer ribs, breaking the whole up into a reticulate pattern. 



Length 0.50 to 0.75 mm. 



Distribution. — The only station at which this form occurred in the 

 North Pacific material is Nero station 1122 in 1,926 fathoms, between 

 Yokohama and Guam. 



This species is close to L. desmopliora and represents a higher de- 

 velopment of the surface ornamentation in the transverse ribs and 

 consequent reticulation of the surface.
