Description. — Test flask-shaped, usually globular with a short 

 stout neck, surface ornamented with an irregularly placed series of 

 beadlike blunt spines. 



Length 0.6 mm. 



Distribution. — Brady records this species from two Challenger sta- 

 tions in the North Pacific in 2,050 and 2,300 fathoms. I have seen 

 it but once, from Nero station 172 in 2,086 fathoms near the Midway' 

 Islands and 1463 in 951 fathoms near Guam. 



In this specimen there is a tendency for the ornamentation on the 

 neck to be linear in its arrangement and a definite phialine lip is 

 present.

 ser. 2, vol. 19, 1857, p. 278, pi. 11, fig. 25. 



Description. — Test subglobular, broadly rounded at the apical end, 

 bluntly pointed at the apertural end, surface reticulated, the aper- 

 tural end of each areole being arched, giving the appearance of over- 

 lapping scales. 



Length 0.25 to 0.50 mm. 



Distribution. — I have had material of this species from the follow- 

 ing North Pacific stations: Tuscarora 2, lat. 2,1° 07' N.; long. 158° 

 14' W.,in 1,468 fathoms and 41, lat. 33° 38' N.; long. 120° 38' W., in 

 530 fathoms; Nero stations 201 in 1,033 fathoms near the Midway 

 Islands and 1065 in 1,321 fathoms north of Guam; and Albatross 

 station D4825 in 120 fathoms off Japan. 



This species may be distinguished from L. Jiexagona and its varie- 

 ties by the form of the reticulations.
