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

 sand deposits. In this limestone, I^o. 924, M. suhrotunda is fairly- 

 common,

A specimen occurs in this limestone, probably referable to the 

 above species. 



? Uvigerina, near bnmnensis, Karrer. 



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

 pi. xvi^>, 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 TJvigerina. In outline it may be compared 

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

 strata at Berchtoldsdorf, near Yienna. Our specimen has a rather 

 large globose primordial chamber. The test measures -^i inch 

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



Glohigerina hulloides, d'Orbigny. 

 One specimen occurs in our slides of No. 924. 



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

 Kep. 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 IN'o. 924. 



Planorhulina, sp. near acervalis, Brady. 



Growing upon some of the larger organisms, and also upon 

 fragments of consolidated material in the rock, maj' be seen many 

 specimens of an adherent foraminifer, possibly to be referred to the 

 above species.^ The chambers arc more crowded or compressed 

 in this form than in the somewhat similar Oypsina inhcerens. 



Truncatulina lohatula ("W. & J.). 



A solitary specimen of the above was noticed in our sections 

 of No. 924.
