D. vilardeloana, pi. Ixxxviii, fig. 2, which Heron-Allen and Earland 

 consider should be placed under D. peruviana d'Orbigny. 



Discorhina squamula Reuss. 



Discorbina squamula Eeuss, 1867, Sitz. k. Ak. Wiss. Wien., vol. Iv. (i), 

 p. 101, pi. V, fig. 2. 



This is a weak form of D. rosacea, but as Mr. Earland considers 

 it identical with I), squamula Eeuss, it is perhaps worth while 

 recording it under that name. Nine occur. 



Discorbina cor a (d'Orbigny). 

 Bosalina cora d'Orbigny, 1839, Foram. Amer. Merid., p. 45, pi. vi, figs. 19-21. 



There are only two examples, and they are not quite typical, 

 although much depressed and sharp edged. The final chamber 

 occupies a much larger portion of the superior face of the test than 

 is usual in this species. 



Discorbina araucana (d'Orbigny). 



Bosalina araucana d'Orbigny, 1839, Foram. Amer. Merid., p. 44, pi. vi, 



figs. 16-18. 

 Discorbina araucana Brady, 1884, Chall. Rept., p. 645, pi. ixxxvi, figs. 10, 11. 



The tests are small and not quite typical. 



The limbation along the sutural lines is concave, and broad 

 considering the size of the test, and there is no lobulation of the 

 peripheral edge. 



Discorbina rosacea (d'Orbigny). 



Rotalia rosacea d'Orbigny, 1826, Ann. Sci. Nat., vol. vii, p. 273, No. 15, 



Modele No. 39. 

 Discorbina rosacea Flint, 1899, Rept. U.S. Nat. Mus. for 1897 (1899), 



p. 327, pi. Ixxii, fig. 3. 

 D. rosacea. Heron-Allen and Earland, 1913, Clare Isl. Foram., Proc. Roy. 



Irish Acad., p. 124, pi. xi, figs. 7-9. 



The examples are not quite typical, having a strong tendency 

 towards the Asterigerina planorbis d'Orbigny, of the Vienna 

 Memoir. The asterigene chambers in the umbilical region are 

 rounded off and not star-shaped. 



Discorbina isabelleana (d'Orbigny). 



Bosalina isabelleana d'Orbigny, 1839, Foram. Amer. Merid,, p. 43, pi. vi, 



figs. 10-12. 

 Discorbina isabelleana Brady, 1884, Cball. Rept., p. 646, pi. ixxxviii, fig. 1. 



Excellent specimens occur in beautiful condition. 



Discorbina concinna Brady. 



Discorbina concinna Brady, 1884, Chall. Rept., p. 646, pi. xc, figs. 7, 8. 



The examples agree in all respects with Brady's figures in the 

 above reference.
