Test elongate, somewhat fusiform, or the basal portion somewhat 

 inflated and later chambers becoming nearly miiserial; chambers 

 inflated, later ones particularly rather distinct, early ones sometimes 

 obscured by the ornamentation of the surface; sutures slightly de- 

 pressed, fairly distinct; wall ornamented by numerous, fine, short, 

 rather evenly distributed spines, covering the entire surface, often even 

 on the neck itself; aperture elongate, cylindrical, in well-preserved 

 specimens with an everted lip, apertural opening being rounded. 

 Length, up to 1 mm.; breadth, 0.20-0.35 mm. 



This has proved to be a rather common species in our Tropical 

 Pacific material, but it is a species of comparatively deep water and 

 has not occurred at the shallower water stations about the various 

 slands. Its distribution with data is given in table 20.

Test much elongated, the early chambers in a close spiral, later 

 ones drawn out and considerably separated from one another, in an 

 irregular loose spiral, the later chambers particularly being somewhat 

 concave below, the peripheral angle angular and projecting, upper 

 surface convex and ornamented by coarse longitudinal costae which 

 project slightly at the periphery making it serrate; sutures distinct, 

 depressed; wall calcareous, usually opaque, ornamented as already 

 noted; aperture with an elongate tubular neck, but the lip usually 

 only slightly developed. Length, up to 0.65 mm.; breadth, 0.20 mm. 



The records for this species are almost enthely from the Pacific. 

 The other records referred to this are probably not the same. Our 

 specimens are mostly from off Levuka, Fiji, in 12 fathoms, where it 

 is common. It also occurs in shallow water near Nairai, Fiji, but the 

 few other records are from Albatross stations, data for which are 

 given in table 21. These, strangely enough, are all from the western 

 part of the area in which the Albatross dredged. The following 

 variety is very distinct.
