I860.] JONES AND PAEKEB FOKAMINTFETU. 301 



Vienna Basin have been elaborately studied by D'Orbigny, Czjeck, 

 and Beuss. We find in their works figures and descriptions of nearly 

 every form mentioned in our columns Nos. 12-24, and a large 

 majority also of the species and varieties that are found living in 

 the Mediterranean. 



One of these deposits (marl at Nussdorf) is abundantly rich with 

 Amphisteyince. Here also Alveolina occurs, as well as at Baden. 

 These forms are extinct as to the present Mediterranean. Orbiadina, 

 as a small variety, has been found fossil at Buitur in Transylvania* ; 

 this also we have not met with living in the Mediterranean, though 

 others have mentioned it. 



The forms figured by Czjeck may be for the most part regarded as 

 intermedia between the bolder forms figured in D'Orbigny's great 

 work ; at the same time they comprise some verj important varieties, 

 and a few are new varietal types. 



Beuss also has figured, besides a few new forms, numerous inter- 

 media, most of them being delicate varieties of the subspecies so 

 well shown in the large work by D'Orbigny, and of considerable 

 value to the zoologist. 



No. 28. Baljik. (Capt. Spratt.) 



A whitish marl characterized by a few peculiar forms, some of 

 them extremely rich in individuals. The Pohjstomelhti and Nonio- 

 nince afford midtitudes of minute specimens, and also the beautiful 

 and rare spinose form termed P. lieyina by D'Orbigny ; it is the 

 P. unguiculata, Gmel. sp. D'Orbigny had it from the Vienna Basin ; 

 Gmelin's specimen came from the Bed Sea. Vertebralina incequalis, 

 Gmel., obtained by Spongier, and also by ourselves, from the sand 

 of tin' Ued Sea, and which is common in the Calcaire Grossier of 

 Grignon, occurs in the Baljik marl, common and large. A few 

 MiUolce and La<j< //" , and an occasional Rot«/!<t Brccarii and Nube- 

 cularia complete the list of Foraminifera obtained by the careful 

 examination of some pounds of this marl. 



We have here evidently an old sea-bed of the seaweed-zone (pro- 

 bably at a depth of from 10 to 20 fathoms), having relations, it would 

 sci'in, rather with the fauna of the Bed Sea than with that of the 

 Mediterranean. 



Notes on the Species ami Varieties. — Many of the species and 

 varieties mentioned in the foregoing Table have been named (as 

 species) by D'Orbigny in the 'Annales dee s-. Nat./ after figures 

 published in Boldani'e ' Testaceographia ' and 'Saggio Orittogra- 

 ficot;' and, as we have had the opportunity! of referring at our 

 Leisure to Soldani'a great work, we have verified and adopted these 

 names, often to the exclusion of synonyms that have been needlessly 



multiplied in works subsequent to those of the authors mentioned.
