p. 349, pi. 13, fig. 22; pi. 16, fig. 9a. 



Description. — Test in front view oval, elliptical, or nearly circular, 

 with a more or less elongate neck, in cross section subcircular; wall 

 smooth, usually transparent; aperture at the end of the elongate 

 neck, which often has a phialine lip. 



Length up to 0.8 mm.; diameter up to 0.4 mm. 



Distribution. — This species from the records would seem to be very 

 common everywhere in the present oceans and in all the geological 

 formations in which Foraminifera occur, but in the North Pacific 

 material examined the species has occurred but a few times. Brady 

 records it from several stations, but none of the figures in the Clial- 

 lenger report represent the typical species, and most of them may 

 be referred to other things. All the specimens I have had came 

 from the Nero and Albatross material dredged off Japan and be- 

 tween there and Guam, in 437 to 2,250 fathoms. Bagg records it 

 from off the Hawaiian Islands and Goes from the western coast of 

 America. 



The synonymy of this species is interesting, including a very great 

 range of things, some smooth, others striate, hispid, and variously 

 ornamented, and in form a great many varied shapes are placed 

 here. Without the original material it is useless to try to straighten 

 out this perplexity of figures, as some of them in the older works are 

 more or less conventionalized. 



It is interesting to note the lack of records for this species in some 

 of the works of more careful students. From this and my own expe- 

 rience the question of the very general distribution of this species 

 may be raised.

 Lagena acuta Fornasini, Boll. Soc. Geol. Ital., vol. 7, 1888, p. 47, pi. 3, fig. 6. 



Description. — Test somewhat elongate, compressed, in front view 

 pyriform, broadest toward the aboral end, tapering gradually to the 

 bluntly pointed apertural end, aboral end with an acutely pointed 

 tip, more or less prominent, wall smooth, aperture elongate elliptical, 

 extending to the central chamber by a fairly long neck. 



Length about 0.75 mm.
