40 Dr. E. P. Wright on Foraminifera. 



III. — Notes on Foraminifera. By E. Perceval Wright, 

 M.D., F.L.S., Professor of Botany in the University of 

 Dublin, Secretary of the Royal Irish Academy. 



While at the Seychelles, in 1867, I made several collections 

 of the Foraminifera met with while dredging. These were, 

 for the most part, preserved in spirits of wine, and mifortunately 

 were lost. One dredging, made in about eight fathoms of water, 

 off the entrance of the harbour of Port Victoria, between the 

 island of St. Anne and Long Island, however, was preserved 

 in a dry state ; the bottom consisted for the most part of a 

 coarse white sand, mixed with fragments of shells, spicules of 

 Alcyonariaus, and fragments of coral, and evidently contained 

 numbers of Foraminifera. A little bottle of dredged stuff from 

 Mahe harbour turned up subsequently ; and the mud and sand 

 washed from the corals and echinoderms which were brought 

 home helped to make up a more or less representative batch of 

 material. The whole was forwarded to my friend Henry B. 

 Brady, F.R.S., of Newcastle-on-Tyne, for examination; and 

 I am indebted to him for the following list of the species 

 found and the accompanying notes upon them. 



Seychelles Foraminifera^ 



1. Cornuspira foliacea, Philippi, sp. (1844, Orhis foliaceus, Enum. 



Moll. Sieil. vol. ii. p. 147, pi. 24. fig. 26), Medium-sized spe- 

 cimens, rare. 



2. Biloculina elongata, D'OrbigTiy (1826, Ann. Sci. Nat. vol. vii. 



p. 298. no. 1). Rare. 



3. Biloculina contraria, D'Orbigny (1846, For. Foss. Yienne, p. 266, 



pi. 16. figs. 4-6). Yery rare. 



4. Triloculina trigonula, Lamarck, sp. (1804, Miliolites trigo7iula, 



Ann. Mus. vol. v. p. 351. no. 3). Rare. 



5. Triloculina ohlonya, Montagu, sp. (1803, Vermiculum ohlongum^

pi. 10. figs. 6-8). Somewhat rare. 



7. QuinquelocuUna seminulum, Liune, sp. (1767, Serpula seminulum, 



Syst. Nat. 12th ed. p. 1264. no. 791). Rather common. Also 

 several specimens of a concave variety, with thick margin, not 

 answering very well to any figured species.

p. 303. no. 43— Modele no. 96). Rare.

rotunchcm, Test. Brit. p. 521). Rare. 



10. QuinquelocuUna Ferussacii, D'Orbigny (1826, Ann. Sci. Nat. 



vol. vii. p. 301. no. 18— Modele no. 32). 



11. QuinquelocuUna antillarum, D'Orbigny (1840, Foram. Cuba, 



p. 167, pi. 12. figs. 4-7). Rare.
