Discorbina jnilvinata Brady, 1884, PC, p. 650, pi. 88. figs. 10, a, b. 
Sidebottom, 1904, etc., RFC. 1908, p. 14, pi. 5. tig. 4.

Frequent, and the specimens vary between relatively smooth and highly 
corrugate on the superior face. Nearly all of them exhibit " budding" in 
various stages, from a single minute primordial chamber in the umbilicus of 
the oral side to specimens in which the base and internal septa have disap- 
23eared by absorption. Two individuals with young brood clustered round 
the orifice were observed, which we figure. 
161. DiSCOEBiNA PATELLiFOKMis Brady. 
Discorbina patelliformis Brady, 1884, FC. p. 647, pi. 88. fig. 3; pi. 89. fig. 4. 
Sidebottom, 1904, etc., RFD. 1908, p. 14, pi. 5. fig. 3. 
Heron-Allen & Earland, 1914-15, FKA. p. 703, 
pi. 52. fig. 32. 
Very common and attaining a large size. The specimens are perfectly 
preserved and very handsome. One " budding " pair of small individuals 
was observed. 
162. Discorbina harmeei Heron-Allen Sf Earland. 
Discorbina lumneri Heron-Allen & Earland, 1922, TN. p. 204, pi. 7. figs. 9-11. 
One minute but typical specimen. It is interesting to note the occurrence 
of this recently described species in a new area, though it is evidently not 
firmly established there. 
163. Discorbina tabbrnaculaeis Brady. (PI. 36. figs. 47-49.) 
Discorbina tabernacularis Brady, 1884, FC. p. 648, pi. 89. figs. 5-7. 
Heron-Allen & Earland, 1914-15, FKA, p. 704. 
Common and quite typical. Many "budding" and associated pairs ; also 
individuals with the base and septa eroded. A specimen of the latter where 
the internal cavity was filled with young individuals (fig. 49). 
164. Discorbina laueiei, nom. nov. (PI. 36. figs. 50-52 ; PI. 37. figs. 53-55.) 
Discorbina tabernacularis Sidebottom, 1910, REBP. p. 25, pi. 3. fi-g. 12. 
The little test figured by Sidebottom though doubtless allied to I), taber- 
nacularis cannot be taxonomically referred to that species. It has many 
points of distinction : the paucity of chambers, which rarely exceed two con- 
volutions of five chambers each; its blunted, or rounded, apex, with a 
prominent primordial chamber; its greatly inferior but constant size; and 
perhaps, most of all, its constant habit of " budding " pairs. Specimens 
which do not present this feature are so uncommon as to be noticeable. It
