around certain coasts ; and it is especially common in some coral- 

 sand deposits. In this limestone, No. 924, M. suhrotimda is fairly- 

 common. 



Ifiliolina 'io'blonga (Montagu). 



Vcrmleuhun oblongum, Montagu, 1803, Test. Brit., p. 522, pi. xiv, fig. 9. 

 MiUolina oblonga (Montagu), Brady, 1884, Rep. ChalL, vol. ix, p. 160, pi. v, 

 figs. 4a, b. 



A specimen occurs in this limestone, probably referable to the 

 above species. 



? Uvigerina, near brunnensis, Karrer. 



Uvigerina brunnensis, Karrer, 1877, Geol. k. F.-J. "Wasserleitung, p. 385, 

 pi. xvii, fig. 49; Brady, 1884, Rep. Chall., vol. ix, p. 577, 

 pi. Ixxv, figs. 4, 5. 



This is a vertical section of a test which closely resembles 

 a strongly inflated Uvigerina. In outline it may be compared 

 with the above form, which was recorded by Karrer from Tertiary 

 strata at Berchtoldsdorf, near A^ienna. Our specimen has a rather 

 large globose primordial chamber. The test measures -„V inch 

 (1-04 mm.) in length, which is equal to other recorded specimens. 



Glohigerina bulloides, d'Orbigny. 

 One specimen occurs in our slides of JS'o. 924. 



Glohigerina conglobata, Brady. (PI. XX, Fig. 3.) 



Brady, 1879, Quart. Journ. Micr. Sci., new sen, vol. xix, p. 72; idem, 1884,, 

 Rep. ChalL, vol. ix, p. 603, pi. Ixxx, figs. 1-5 ; pi. Ixxxii, fig. 5. 



This appears to be the first recorded occurrence of the above- 

 species in the fossil condition. Two fine specimens were seen in 

 our sections of Xo. 924. 



Planorbulina, sp. near acervalis, Brady. 



Growing upon some of the larger organisms, and also upon 

 fragments of consolidated material in the rock, may be seen many 

 specimens of an adherent foraminifer, possibly to be referred to th& 

 above species.^ The chambers are more crowded or compressed 

 in this form than in the somewhat similar Oyp&ina inhmrens. 



Truncatulina lohatula (W. & J.). 



A solitary specimen of the above was noticed in our section* 

 of No. 924.
