20 Messrs. Parker, Jones, and Brady on the 



Model no. 8. Quinqueloculina Lyra, D'Orb. Page 303, no. 45. 



Hab. Adriatic and Mediterranean. PI. I. fig. 11. 



A thin, narrowish Miliola, with subsigmoid, somewhat cari- 

 nate chambers. 



Model no. 9. Bulimina elegans, D'Orb. Page 370, no. 10. 



Hah. Adriatic, near Rimini. PI. II. fig. 64. 



Bulimina Preslii, Reuss, figured in the ' Verst. Kreid. Bohm.* 

 (1846), pi. 13. fig. 7.2, and in Haidinger's 'Naturwiss. Abhand.' 

 vol. iv. (1850), Kreidemergels von Lemberg, pi. 3. fig. 10, is the 

 best type of the genus Bulimina. B. elegans is a delicate va- 

 riety, narrower and less robust in growth, as well as more im- 

 bricated in the disposition of the chambers. 



Model no. 10. Rotalia Menardii, D'Orb. Page 373, no. 36. 



Hah. Adriatic, near Rimini. PI. III. fig. 81. 



This must be placed in the genus Pulvinulina, being a good 

 subspecies of P. repanda. It is found in deep water, and is 

 seldom abundant, except in Tropical seas. One or two beautiful 

 specimens have occurred to us on our own coast, in sand dredged 

 from deep water ofi" the Isle of Man. 



Model no. 11. Nonionina Limba, D'Orb. Page 594, no. 14. 



Hah. Adriatic, near Rimini. PI. III. fig. 99. 



A variety of the subtype N. asterizans, F. & M., from which 

 it [difi^rs in the greater development of the stellate sutural 

 limbation, and in possessing a narrow thick keel, instead of the 

 rounded edge of the subtype. The same variety, but with 

 stouter and somewhat encrusted shell, occurs fossil in the 

 neighbourhood of Bordeaux. 



Model no. 13. Rotalia punctulata*, D'Orb. Page 373, no. 35. 



Hab. Adriatic, near Rimini. PI. Ill, fig. 83. 



This is a Pulvinulina, and not a Rotalia ; it is perhaps even 

 a more fully developed form than the type, P. repanda, P. & M. 

 We have found fine handsome specimens in dredgings from the 

 coast of Norway. 



Model no. 13. Gyroidina orbicularis, D'Orb. Page 378, no. 1. 



Hab. Adriatic, near Rimini. PI. III. fig. 85. 



The thin-shelled, somewhat globular variety of Rotalia Bec- 

 carii, inhabiting deepish water, usually much smaller than the 

 common shallow-water form. It is a widely distributed variety, 

 and has been found on our own coast, in the Irish Sea and off 

 the Shetland Islands.
