plates are from carefully made camera lucida drawings and have 

 sufficient detail so that it is hoped the characters of the specimens 

 of the collection will be adequately given. Descriptions of the 

 species follow.

 biserial, few; wall coarsely arenaceous, smoothly finished; aperture 

 a narrow slit at the inner margin of the last-formed chamber.

Family MILIOLIDAE 



Genus QUINQUELOCULINA d'Orbigny, 1823 



QUINQUELOCULINA VULGARIS d'Orbigny 



Plate 1, figures 7 a-c 



Quinqueloculina vulgaris d'Orbigny, Ann. Sci. Nat., vol. 7, 1826, p. 

 302. — Terquem, Mem. Soc. Geol. France, ser. 3, vol. 1, 1878, p. 66, pi. 6 

 (11), figs. 20a-21. 



There are a few specimens in the collection similar to that figured 

 which may be referred to this species of d'Orbigny. The wall shows 

 a few longitudinal costae. 



QUINQUELOCUUNA LAEVIGATA d'Orbigny 



Plate 1, figures 4 a-c 



Quinqueloculina laevigata d'Orbigny, Ann. Sci. Nat., vol. 7, 1826, p. 301; in 

 Barker, Webb and Berthelot, Hist. Nat. lies Canaries, 1839, vol. 2, pt. 

 2 "Foraminiferes," p. 143, pi. 3, figs. 31-33. 



A few specimens with smooth surface and general shape as that 

 given on Plate 1, figure 4, are referred to this species of d'Orbigny. 

 From the records, this species seems to have a very wide range, but 

 this is probably due to its smooth surface and lack of more definite 

 characters. 



Length 0.27 mm., breadth 0.13 mm.
