the size and regularity of tlie hexagonal markings. It reaches its finest develop- 

 ment in the deep-water Stations, between Stations 16 and 22, where it attains 

 considerable size, and the hexagonal reticulation is large and strongly developed. 

 The liest individuals occur at Stations 23. 27 and 31.

Two large specimens from almost farthest South, one presenting a single 

 aperture, the other several, surface comparatively smooth. While generally agreeing 

 with Chaster's opinion quoted by Sidebottom. ut supra (1912, p. 427), we believe 

 that L. protea, like many other Lagenae, has a tendency to produce a secondary 

 aperture or apertures. The species was referred to EaiuaUiia by Jones and 

 Chapman (J. & C. 1896-8, FPR. 1898, p. 342, fig. 11), but its referability 

 to Lagena was fully discussed in the letter of Chaster to Sidebottom, cited in 

 his paper (uf siipni). We have no hesitation in ascribing Pearcey's L. hispidi- 

 pholus to this form.

Almost universallv (listril)uted, but attaining its best development at the 

 deep-water Stations. In addition to the usual type, two punctate or coarsely 

 perforate, and finely perforate forms occur. The coarsely punctate form is most 

 typical in the N.Z. area (Stations 2 and 3), but it occurs also at Station 53. The 

 finely punctate form is more abundant in the deep-water Stations, but also occurs 

 in the circum-polar Stations, especially Station 53. There is the usual Avide 

 variation in the comparative length and breadth of the shell, exceptionally long 

 specimens at Station 26.
