 apertural end tapering; chambers comparativel}' few, somewhat in-

 ture radiate. 



Length up to 1 mm. 



Distrihution. — This species has occurred at several stations in the

 "Wliether the two lots of material are really the same species or not 

 is questionable.

POLYMORPHINA OVATA D'Orbigny. 



Plate 40, figs. 11, 12. 



Polymorphina ovata D'Orbigny, Forara, Foss. Vienne, 1846, p 233, pi. 13, 

 figs. 1-3.— H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, 

 p. 564, pi. 72, figs. 7, 8. — Peabcey, Trans. Glasgow Nat. Hist. Soc, 

 vol. 2, 1890, p. 178.— Goes, Bull. Mus. Comp. Zool., vol. 29, 1896, p. 54. 



Under this specific name Brady records specimens from a single 

 Challenger station off Culebra Island, West Indies, 390 fathoms 

 (713 meters). I have had it in West Indian material which seems 

 identical with this. It has been recorded from the eastern Atlantic, 

 as the above records will show. 



POLYMORPHINA OBLONGA D'Orbigny. 



Polymorphina ohlonga D'Okbigny, Foram. Foss. Vienne, 1846, p. 232, pi. 

 12, figs. 29-31. — H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 

 1884, p. 569, pi. 73, figs. 2, 4.— Flint, Rep. U. S. Nat. Mus., 1897 ( 1899), 

 p. 319, pi. 67, fig. 5 [?]. 

 Flint records this species from off the southeastern coast of the 

 United States, but most of the material from this same station be- 

 longs to Polymorphina flintii Cushman. There arc many records 

 from Eastern Europe referred to P. ohlonga., Williamson's form, 

 which he described as P. lactea^ var. ohlonga^ and which by several 

 authors has been placed as a valid species. 



It is obvious that with D'Orbigny's earlier name Williamson's 

 variety can not be used in a specific sense.
