FORAMINIFERA OF THE WEST OF SCOTLAND. 215 



8 Stations. 



This little form, which appears to he nothing more than a smooth type of W. bicornis, 

 is very sparingly represented in the dredgings, but good specimens and also adelosine 

 examples occur occasionally, the best at Stn. 18. 



It should he noted that the synonymy of this species as given hy us in our Clare 

 Island Report requires correction, the Quinquelocidina laevigata of d'Orbigny having 

 been confounded with his Adelosina laevigata when the references were compiled. The 

 first two references to d'Orbigny, 1826, TMC. (ASN.), and 1839, PIC, should be removed 

 and the above synonymy substituted. 



An examination of the d'Orbigny types in Paris shows that his species Triloculina 

 dubia (d'O. 1826, TMC. p. 300. No. 24) is identical with this form. 



44. Miliolina stelligera (Schlumberger). (Plate 39. figs. 28-31.)

6 Stations. 



Very rare, the only Stn. where more than one or two specimens were observed being 

 Stn. 18. The 'Puna' specimens are more strongly carinate and more deeply sunk in the 

 sutural lines than is shown in Schlumberger's figure, and we take this opportunity of 

 figuring the form, as the ' Rama ' specimens are much stronger than those which we 

 figured from Clare Island. The surface of the tests is uniformly dull and unpolished. 



Subgenus Massilina, Schlumberger. 



45. Massilina secans (d'Orbigny). 



Quinqueloculina secans, d'Orbigny, ]826, TMC. p. 803, No. 43, Modele No. 96. 



Miliolina secans, Brady, 1884, FC. p. 167, pi. vi. figs. 1, 2. 



Massilina secans, Schlumberger, 1893, MGM. p. 76 (woodcuts figs. 31-34), pi. iv. figs. 82,83. 



8 Stations. 



Very rare, except at Stns. 7 and 8, where, however, the individuals were small and weak 

 compared to those of the other Stns. where only one or two specimens were obtained, 

 but these large and typical. The extraordinary rarity of this form down the West of 

 Scotland is very noticeable, considering its abundance on the western English and Irish 

 coasts. It is equally dominant in the shore-sands of Scapa, Orkney — the gaps in the 

 distribution of the form are inexplicable. 



Subfamily Hattek.ini.njb. 

 Opthalmidium, Kiibler. 



46. Opthalmidium carinatum, Balkwill & Wright. 



Opthalmidium carinatum, Balkwill & Wright, 1885, DIS. p. 326, pi. xii. figs. 13-16.
