tuberculate "with vertical rows of puncta, not perforations." They 

 appear very similar to perforations, but unfortunately there is only 

 the holotype in the British Museum, and it could not be sectioned 

 to determine the wall structure. 



Genus SCHUBERTIA Silvestri, 1912 

 Plate 4, figure 3 



Original description. — Riv. Italiana Paleont., vol. i8, fasc, 2, 3, 

 p. 68, 1912 (new name for Millettia Schubert, 191 1, Abh. K. K. Geol. 

 Reichsanst. Wien, Osterreich, vol. 20, heft 4, p. 89 [not Millettia 

 Duncan, 1889, and not Wright, 1899]). 



Type species. — Sagrina tessellata Brady, 1884. Subsequent designa- 

 tion by Schubert (1911, review, p. 320). 



Diagnosis. — Test free, elongate, narrow, arcuate, very early portion 

 biserial, later portion consisting of a few elongate subcylindrical 

 chambers, rapidly increasing in height and subdivided into chamber- 

 lets by vertical and horizontal partitions in a honeycomb pattern, the 

 chamberlets arranged in regular transverse rows ; wall calcareous, 

 surface marked into hexagonal patterns by the junction of the cham- 

 berlet walls with the outer wall; aperture terminal, rounded with a 

 slight lip. 



Types. — Lectotype here designated as the specimen figured by 

 Brady (1884, pi. 76, fig. 17) deposited in the B.M.N.H., No. ZF 2359, 

 from Challenger station No. 2i9A,at a depth of 17 fathoms. Admiralty 

 Islands. 



Discussion. — Cushman stated (1929a, p. 338) that Brady's species 

 showed no early biserial stage and that all chambers were subdivided. 

 Examination of the type specimen shows 2 pairs of biserial chambers 

 and an undivided uniserial chamber before the subdivision into 

 chamberlets. 



However, both Cushman (1948, p. 270) and Galloway (1933, 

 p. 376) correctly describe the genus as having an early biserial stage 

 followed by uniserial chambers, at first undivided and later with 

 chamberlets.

 Monotypic.
