Distribution. — This variety was obtained at Albatross station, 

 D2806 in 1,379 fathoms off the Galapagos Islands. 



The two added characters of a fluted truncate conical neck with the 

 basal outwardly curving spines seem to be correlated and the form 

 worthy of recognition.

 Lagena vulgaris, var. substriata Williamson, Rec. For. Great Britain, 1858, p. 7, 



pi. 1, fig. 14. 



Description. — Variety differing from the typical in the more elon- 

 gate body, long tapering neck, costulate surface extending up onto 

 the neck often to its end and usually spirally arranged on the neck. 



Length 0.4-0.5 mm. 



Distribution. — This variety seems to be much more common in the 

 North Pacific than the others. It occurred at Tuscarora station 9 in 

 lat. 31° 51' N.; long. 119° 3' W., in 980 fathoms. It has also 

 occurred at numerous Albatross and Nero stations off Japan in depths 

 ranging from 33 to 1,529 fathoms, but one station, however, being 

 over a thousand fathoms.

 Plate 7, figs. 7-10. 



Lagena strumosa Reuss, Zeitschr. geol. Ges., 1858, p. 434; Sitz. Akad. Wiss. 

 Wien, vol. 46, pt. 1, 1862 (1863), p. 328, pi. 4, fig. 49. 



Description. — Test clavate, body portion subglobular or slightly 

 fusiform, ornamented with numerous longitudinal costss, the apical 

 end prolonged into a stout spine; neck long and comparatively stout, 

 ending in a phialine lip, which is itself prominently costate, neck 

 ornamented with raised annuli either transversely costate or beaded 

 and sometimes spinose between the annuli. 



Length up to 0.6 mm. 



Distribution. — This is again one of the most common varieties of 

 this species, especially in the material from off the coast of Japan. 

 Near the Midway Islands it occurred at Nero station 105 in 2,370 

 fathoms, between the Midway Islands and Guam at Nero station 542 

 in 1,996 fathoms, between Guam and Yokohama at Nero stations 

 1209 in 660 fathoms and 1301 in 1,088 fathoms. It occurred at 

 several Albatross stations off Japan, the depths ranging from 84 to 

 440 fathoms.
