specimens does not throw much litiht on the difficulties with which 

 we were confronted in dealing with the single individual from the 

 Irish coast. While still of opinion that it is a I'lilvinuJina, its 

 identity with d'Orbigny's type llotalina ]iatu(/onim (d'O. 1839, 

 F.A.M. p. 36, pi. ii, tigs. 6-8) appears rather more doubtful. 

 Halkyard figures under the name Discorhina sp. (H. 1889, E.F.J, 

 p. 70, pi. ii. fig. 11) some individuals which are unquestionably the 

 same as our form. He states that his specimens had been sub- 

 mitted to Brady, who had identified them with " a weak depau- 

 perated form figured by 0. Terquemin his Dunkerque Monograph ,^ 

 which paper 1 have not seen, and therefore cannot ijive the speci6c 

 name which M. Terquem gives to this Foraminifer." The only 

 form of Tercjuem which can be compared with our type is his 

 Ratal ina excuvata (T. 1875, etc. A.P.D p. 128, pi. xv. fig. 5). This 

 has a similarly large loop-like or pulvinuline aperture, but is much 

 higher in the dome and has more visi''L chambers. Brady, in 

 1882 (jit tiu/ira), describes under tlie name I'uJvinulina scitula sp. n.. 

 "A variety of I', canin-ienais (d'Orbigny) diflering from the typical 

 form in its relatively small size and compact habit of growth. The 

 mar.ein is rounded instead of slMrp, and the pcriplieral ends (aic — 

 edges) of the chambers are only slightly convex instead of stand- 

 ing out ])rominently, as in P. canariatsw. Notwithstanding its 

 small minute dimensions, it generally attracts attention by its 

 glistening white appearance. Longer diameter, 0"01." Halkyard's 

 types, which are preserved in the University Museum at Man- 

 chester, have been examined by us, and prove t) be identical witli 

 our fonn. 



No figure was published by Brady, but the description of its 

 appearance leaves very little doubt in our minds that this is the 

 Clare Island form. Balkwill and Millett, in their orii^inal Galway 

 paper (w siqn-a), figur^ a specimen of F. yci.tidu which is stated to 

 ha\ e been identified liy Brady, and which, broadly speaking, is 

 intermediate between 1'. paiaijoiiira (typical) and our Clare Island 

 figiare. In the revision of the Galway paper by Millett (Penzance, 

 1908) the name F. scitula is withdrawn and F. pataf/on'cn sub- 

 stituted, with a statement that the form had been figured us F. 

 scitula "on the faith of Brady, but subsequently he convinced him- 

 self that it was identical with F. pato'ion-ca" 



The Clare Island and Cornish spi cimeus are so distinctive as 

 compared with d'Orbigny's original fij^ure, that it seems desirable 

 that Brady's name should be revived as a variety of F. patagonicu, 

 and we have accordingly adopted this course.

 the Biitish records of this species in our West of Scotland paper. 

 The specimens in the Mdlett Collection entirely confirm the views 

 we have there set forth.
