the exception of Rotalia Mortoiii &r\d Bulimina toriilis (both new species), 

 of which numerous examples are found, the remainder appear seldom. 



Most of them however are very rare. With the exception of the pecul- 

 iarly formed Bulimina toiiilis, all the remaining- species offer nothing re- 

 markable in their external appearance They belong to the ordinary, 

 universally distributed, well-known types. 



The reference in the description of Cris. roUdata: for which the reader 

 is refered to p. 326, is as follows : 



1. Cr. rolulata. Lam. sp, d'Orb. mem. de la Soc. geol. de France, 

 iv. I, 26, pi. ii. figs, q, 15-18. This species, which is commonly distri- 

 buted in the Cretaceous, occurs quite frequently, also in the chalk of 

 Riigen, and in specimens of unusual size. The orifice is not stellate in 

 any of the specimens at hand. In on^, after often repeated and close ex- 

 amination, I could not discover any larger orifice. 



I have mentioned numerous localities where this cosmopolitan species 

 can be found, in my Monograph on the Foraminiferaof Westphalian chalk 

 formation. Sitzungsber. d. k. Akad. d. Wiss. in Wien. , xl. 70. 



The description of R. Bosqneti. on p. 316, is as follows : 



2. R. Bosqneti, n. sp. PI. iii. figs. 9, i. Rare. Differing from the 

 ordinary Rosalina type, more like many Rotalidx with flat oval shells 0.7 

 mm. long, broadly oval, strongly depressed, rounded angular edges, verj' 

 moderately arched spiral side, and somewhat pressed in umbilicate sur- 

 face. The spiral side shows but two whorls, of which the second in- 

 creases rapidly in breadth, and presents 7-8 rather broad, slightly curved 

 chambers, which are separated by linear partially obscure sutures. The 

 central volution not externally divided into chambers on the underside, 

 which has a moderately broad umbilicus. Only the last large chamber 

 somewhat protruded. The remainder of the shell is somewhat hollowed 

 out toward the centre. The slightly curved suture narrow, lA rather 

 deep. The surface of the shell covered with quite large pores.
