FOKAMINIFERA OF JsTOKTH PACIFIC OCEAN. 95 



seem to fit excellently the figure and description of V. striata given 

 by d'Orbigny. The finely costate tapering test and the characters 

 of the apertural portion are very different from the more common 

 material usually referred by authors to TJ. pygmsea.

 485.— von Schlicht, Foram. Pietzpuhl, 1870, pi. 22, figs. 34-36.— H. B. 

 Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 574, pi. 74, figs. 4-7. — 

 Egger, Abb., kon. bay. Akad. Wiss., Miinchen, CI. n, vol. 18, 1893, p. 315, 

 pi. 9, figs. 44, 52. 



Description. — Test elongate, subcylindrical, tapering at the apical 

 end, composed of numerous rounded chambers with distinct sutures; 

 wall with numerous fine raised longitudinal costse, except the distal 

 portion of the last-formed chamber, or in full-grown specimens more 

 than the last chamber, with roughened or even nearly smooth walls; 

 aperture with a short comparatively thick tubular neck with usually 

 a distinct phialine lip. 



.Length about 1 mm. 



Distribution. — Recorded by Brady in the North Pacific in 95 fath- 

 oms off the Philippines. I have not seen material definitely referable 

 to this species from the North Pacific. Bagg's material which I have 

 examined seems to belong to TJ. striata, although recorded by him under 

 the name tenuistriata. 



UVIGERINA STRIATULA, new species. 

 Plate 44, fig. 3. 



Description. — Test elongate, fusiform, tapering gradually from the 

 middle toward either end; composed of numerous inflated chambers, 

 those last formed considerably drawn out, wall usually thin and 

 translucent, finely and distinctly striated; aperture with a tubular 

 neck and phialine lip. 



Length about 0.5 to 0.7 mm. 



Distribution. — Type-specimen, Cat. No. 8551, U.S.N.M., from Nero 

 Station 1310 in 518 fathoms, globigerina ooze, near the Bonin Islands. 

 It also occurred from the same region at Nero Station 1306 in 1,208 

 fathoms, also in globigerina ooze. 



In its extreme modification this species has a general resemblance 

 to U. interrupta II. B. Brady, but most of the specimens examined 

 were less drawn out than is usual in that species.
