species, Cibicides eriksdalensis Brotzen and C. mundula (Brady, 

 Parker, and Jones), but according to the International Rules of Zoo- 

 logical Nomenclature, Art. 25, c (3), a definite statement must be 

 made as to the type species selected in order for a genus to be vali- 

 dated. Therefore, Cibicidoides became a valid genus when Thalmann 

 designated as type species in 1939 Truncatulina mundula Brady, 

 Parker, and Jones, 1888, and the genus must therefore be credited to 

 Thalmann. 



Cushman (1948, p. 335) and Bermudez (1952, p. 87) both errone- 

 ously cite Cibicidoides eriksdalensis Brotzen as type species and credit 

 the genus itself to Brotzen, 1936. Sigal in Piveteau (1952, p. 229) 

 cites the genus as Cibicidoides Brotzen, 1942, and figures C. eriks- 

 dalensis, although not definitely citing it as type species.

 Plate 4, figures 7, 8 



Type species. — Patellina canipanaeformis Brady, Rep. voyage Chal- 

 lenger, vol. 9 (Zoology), p. 634, text figs. I9a-c, 1884. 



Derivation. — Patronymic. Gender, feminine. 



Diagnosis. — Test free, conical, high-spired, ventrally flattened or 

 slightly excavated, consisting of a proloculus and long, undivided, 

 broad and low tubular chamber in a high, open conical spire, the cen- 

 tral area being filled with clear or laminated calcite, tiny pores around 

 the exterior spiral suture, wall calcareous, with the test composed of 

 a single crystal of calcite ; aperture ventral, at the open end of the 

 spiraling tube. 



Types. — Holotype (sectioned specimen, fig. 8), B.M.N.H. No. 

 ZF 2065, is that figured by Brady in text figure 19c, p. 635, from 

 Challenger station 185, off Raine Island, Torres Strait, at 155 fathoms. 

 Paratype (exterior figured, fig. 7), B.M.N.H. No. ZF 3614, from the 

 same locality and the specimen figured by Brady, 1884, text figures 

 I9a,b, p. 635. 



Discussion. — Describing it as a species of Patellina, Brady stated 

 that the species appeared to be biserial at least in part, but that the last 

 whorls were apparently undivided. A careful examination showed no 

 septation, and this form differs from Patellina in having a broad and 

 low undivided tube rather than a biserial series of chambers, in being 

 extremely high-spired, and in having the central portion filled with 

 calcite. There are faint transverse undulations of the ventral surface 

 but no internal secondary septa as in Patellina. It is closer, perhaps, to 

 Trocholina Paalzow, 1922, although the central filling is not in the
