Foraminifera of South Cornivcdl. 35 



11. MilioUna circular is (Bornemann.) (Refs., R-A.. & E. 11(15, F.K.A. 



p. 557.) Universally distri'mted. At many stations the specimens 

 were very thin-shelled and translucent. Chitinoiis tests at Stations 

 III and V. (P.) 



12. M. circularis var. sublineata Brady. (Refs., H-A. & E. 1915, F.K.A. 



p. 558.) I, v.r. 



13. M. Jabiosa (d'Orbigny). (Refs., H-A. & E. 1915, F.K.A. p. 559.) I, v.r. 



14. M. suhrotiinda (Montagu), pi. Y. tigs. 6-8. (Refs., B 188-4, F.C. p. 168; 



H-A. cV' E. 1915, F.K.A. p. 559.) Universally distributed. At 

 many of the stations very thin and translucent specimens. At 

 Station III, where the species was well represented, there were a 

 few individuals of a hauerine type, which we figure. (M.) (P.)(H.> 



15. M. seminuda (Reuss). (Refs., H-A. & E. 1915, F.K.A. p. 560.) Gene- 



rally distributed. Best at V, and most frequent at IX. 



16. M. xub-orbiruluris (d'Orbieny). (Refs., H.-A. A: E. 1898, etc., S.B. 1911,. 



p. 304.) VI, v.r. 



17. M. trigonula (Lamarckj. (Refs., B. 1884, F.C. p. 164.) As a rule very 



small specimens. 11, III, V, VII, IX, v.r. (M.) (P.) 



18. M.trlmrinata (d'Orbigny). (Refs., B. 1884, F.C. p. 165; H-A. & E. 



1915, F.K.A. p. 56-2.) I, III, v.r. ; V, r. (M.) (P.) 



19. M. bosciana (d'Orbigny). (Refs., H-A. & E. 1915, F.K.A. p. 566.) Gene- 



rally distributed. 



20. M. oUonga (Montagu). (Refs., B. 1884, F.C. p. 160 ; H-A. & E. 1915, 



F.K.A. p. 566.) Universally distributed. At Stations I, II, V and 

 VII, Williamsdus stoppered or opereulate variety (W. 1858, R.F.G.B. 

 p. 86, pi. vii. figs. 186, 187) occurs in company with the normal 

 milioline type of Montagu. At the remaining stations the normal 

 type only was found. (M.) (P.) (R.) 



21. M. pygmsea (Reuss). (Refs., H-A. & E. 1915, F.K.A. p. 567.) V, f. 



(M. as M. tenuis (Czjzek), and M. 1906 as Sigmuilma tenuis.) 



22. M. rotunda (d'Orbigny). (Refs., H-A. & E. 1915, F.K.A. p. 568.) A 



single typical specimen at Station II. 



23. M. seminulum (d'Orbigny). (Refs., B. 1884, F.C. p. 157.) Universally 



distributed. An unusual form of distortion was observed at Station 

 IV, the last two chambers being formt d with their axes at right 

 angles to that of the earlier chambers, thus projecting from the 

 middle portion of the shell and presenting the aperture of the ante- 

 penultimate chamber in the middle of the test. (M.)^(P.) (R.) 



24. M. candeiana (d'Orbigny). (Refs., H-A. & E. 1913, C.I. p. 29, and 1916, 



F.W.S. p. 212, pi. xxxix, figs. 19-27.) This very obscure species is 

 found in great numbers at Station I, and presents a greater range of 

 variation than we have observed elsewhere. In the early stages it 

 is often distinctly spiroloculme in the arrangement of its chambers, 

 the milioline form not being assnmed until the specimens have 

 attained a considerable size (five to six chambers). Its affinities still 

 remain very uncertain, and, as we have observed elsewhere, the tvpe 

 specimens on which the species was originally recorded as British 

 are nowhere to l)e found. I, v.c. ; II, f. ; IV, V, VI, IX, v.r. (M.) 



25. M. auberiana (d'Orbigny). (Refs., H-A. & E. 1915, F.K.A. p. 571.) 



Universally distributed.
