NODOSARIA LONGIROSTRATA, new species. 

 Plate 27, fig. 8. 



Description. — Test elongate, composed of few very elongate cham- 

 bers, sutures slightly depressed, wall smooth, aperture at the end of 

 a long tubular neck, somewhat clavate at the tip with several flange- 

 like extensions, bicarinate. 



Length of broken specimen 2.50 mm. 



Distribution. — Type-specimen, Cat. No. 8545, U.S.N.M., from 

 Albatross station D4949 in 110 fathoms, off Japan, bottom tempera- 

 ture 57.8° F. 



This is a very elongate species, the chambers being several times 

 as long as wide and the peculiar form of the apertural end makes it 

 especially distinctive.

Nodosaria longicauda d'Orbigny, Ann. Sci. Nat., vol. 7, 1826, p. 254, No. 28. 



Description. — Test composed of few nearly spherical chambers, 

 rapidly increasing in size as added, apical end often with a spine, 

 surface ornamented with numerous longitudinal raised costae, aperture 

 at the end of a fairly long neck ornamented with transverse ring-like 

 costse. 



Length 1.50-3.00 mm. 



Distribution. — From the material I have examined this species 

 seems to be the most common in the region. Brady records it from 

 two Challenger stations, off the Philippines, 95 fathoms, and off the 

 south coast of Japan on the Hyalonema-groxmd, 345 fathoms. Bagg 

 records it from Albatross station H4566 in 572 fathoms off the Ha- 

 waiian Islands. I have had material from a large number of sta- 

 tions, off the Hawaiian Islands, off Guam, and especially between 

 Guam and Japan. The depth varies from 84 to 1,503 fathoms. 



There is a considerable variation in the number and prominence of 

 the costae in different specimens and also in the various chambers of 

 the same specimen as in plate 24, figure 7. The aperture is inter- 

 esting, often being surrounded by several tooth-like prominences.
