Haplojihragmium aggluHnans (d'Orbigny). (PL II, fig. 10.) 



Spirolijia agglutinans d'Orbigny, 1846, For. Foss. Vien, p. 137, pi. vii, 



figs. 10-12. 

 Haplophragmium agglutinans Brady, 1884, Chall. Eept., p. 301, pi. xxxii,. 



figs. 19-26. 



Four varieties. One example typical. Four tests have the 

 initial chambers well compressed, slightly sunk at the umbilicus 

 and the linear portion also flattened at its commencement. Twa 

 specimens have the planospiral portion rather large, and are very 

 rough. One of the two has the linear portion twisted. The fourth 

 variety, fig. 10, PI. II, is very slender. Of the two examples found 

 one is in perfect condition. The test is built of clear sand-grains, 

 and the animal has used very few grains to- each chamber, which 

 gives an angular appearance. Sutures obscure. 



Hajolophragmiiim tenuimargo Brady. 



Haplophragmium tenuimargo Brady, 1884, Chall. Kept., p. 303, pi. xxxiii^ 

 figs. 13-16. 



Two fragments. I believe they belong to one another, and if 

 so they complete the test. Their compression and their jagged 

 edges seem to identify them with this species. 



Haplophragmium latidorsatum (Bornemann) . 



Nonionina latidorsatum Bornemann, 1855, Zeitschr. d. deutsch. geol. Gesell.y 



vol. vii, p. 339, pi. xvi, fig. 4. 

 Hajjilophragmium latidorsatum Bradv, 1884, Chall. Kept., p. 307, pi. xxxiv. 



figs.VlO, 14. 



Four out of the five examples are small. One is attached to a 

 portion of an arenaceous tube. 



Haplophragmium glohigeriniforme (Parker and Jones). 

 (PI. II, figs. 11-14.) 



Lituola nautiloidea, var. globigeriniformis Parker and Jones, 1865, Phil. 



Trans., vol. civ., p. 407, pi. xv, figs. 46, 47 (pi. xvii, figs. 96-98?) 

 Haplojjhragmium glohigeriniforme Brady, 1884, Chall. Kept., p. 312,, 



pi. XXXV, figs. 10, 11. 



The two largest tests, figs. 11, 12, PI. II, are white. The others 

 are of a light rusty-red hue, the final segments being lighter than the 

 rest. One variety is a neat, comparatively smooth form, of a rich 

 ferruginous tint, with three to four chambers in the outermost 

 whorl, PL II, figs. 13, 14. Another variety is larger, and roughly 

 built. The large white specimen, fig. 11, might be passed for 

 H. sphfe-roidiformc Brady, referred to in the " Challenger " Keport, 

 p. 313, as isomorphous with Sph^roidina hulloides, but a close 

 examination hardly supports this view of it. This test is slightly 

 flattened.
