Revieios. — GumheVs Foraminifera, etc. 179 



Ecuss, and Czjzeck, have many of tho Bavarian Eocono Foraminifera, 

 but are deficient in Orbitoides and Nummtilina ; Amphistegina pre- 

 dominating instead, with Miliolince, Polymorphinoc, etc. The Malaga 

 Clay also, and most of the Subappenine Ueds, yield in abundance 

 several of the forms figured by Dr. Gvimbcl, especially the Nodo- 

 sarifKe, and these of larger growth; and tho existing representatives 

 of nearly all the species are found plentifully in the Australasian 

 and other warm seas. In fact, as long ago observed, it is mainly to 

 Australia and the neighbouring regions that we have to look for the 

 successors of the beautiful Foraminifera of the Grignon and other 

 Tertiary sea-beds of Europe. 



In the Scindian equivalents of the European Nummulitic beds, 

 Orbitoides, Alveolince, etc., abound as in Bavaria ; and Orbitoides are 

 abundant in the West-Indian Middle Tertiaries, though rare or 

 wanting in their European equivalents. 



Of the several groups of Foraminifera, arranged according to 

 Carpenter and other English Rhizopodists, the Bavarian list before 

 us supplies the following : — 



MiLioLiDA : Cornuspira, 1 (probably a TrocTiammina) ; Alveolina 

 1. LiTUOLiDA : Trochammina, 1 (?) ; Lituola (HaplopJiragmium), 1 

 Lagenida : Lagena, 4; Glandulina, 1; Lingulina, 2; Nodosaria, 24 

 Dentalina, 14 ; Vaginulina, 3 ; Marginulina, 7 ; Cristellaria (and 

 Bobutina), 16 (Nbdosarince, 71) ; Orthocerina {Mhabdogonium) , 1 

 Uvigerina, 1 ; PolymorpMna (and Globulina), 5. Globigerinida 

 Globigerina, 4:; Clavulina, 1; Gaudryma, 2; Plecanium, 2; Venilina, 

 2; Textilaria, 1 (TextilarincB, 8); Yirgulina (Pleurostomella), 1 

 Discorbina, 2; Planorbulina {Botalia, Bosalina, Truncatulina) , 15 (?) 

 Pulvinulina {Botalia and Bosalina), 3 ; Calcarina, 1. Nummulinida 

 Operculina, 3 ; Nummulina, 16 (not figured) ; Heterostegina, 1 

 Orbitoides, 20. 



It seems probable that further research will supply more of the 

 Miliolida, if not of some other groups also, to bring up this list of 

 genera to the usual complement of such a Ehizopodal Fauna as the 

 above abstract indicates to have existed in the Nummulitic Sea. 



As of interest to Ehizopodists, it may be well here to point out 

 the probable relationship of the Botalince treated of by Dr. Giimbel, 

 who groups them mostly in an old-fashioned manner, as Botalia, 

 Bosalina, and Truncatulina. 1. Discorbina : D. polyspJioerica, pi. 2, 

 f. 95; D. megaspJicerica, f. 96 (=z D. globigerinoides, Parker and 

 Jones). 2. Planorbulina : Botalia megompJialus, f. 94 bis; Bot. 

 pteromphalia, f. 88 ; Truncatulina Tcallomphalia, f. 102 (these three 

 are near PI. ITaidingeri) ; B. truncana, f. 43 (near PL Ungeriana) ; 

 Bot. capitata, f. 92 ; Bosalina rudis, f. 99 ; Truncat, grasserugosa, 

 p. 104 (these three are very near to PI. ammonoides, if not identically 

 the same) ; (subgenus Truncatulina) Bot. ammopMla, £. 90 ; Bot. 

 macrocephala, f. 91 ; Truncat. sublobatula, f. 103 ; Bot. cochleata, 



^ Dr. Giimbel has instituted the new genus Venilina for those Textilarian forms 

 that commence with an alternate series of compressed oblique segments {Grammos- 

 tomum), and end in a single series, such as the bi-uniserial sub-varieties mentioned in 

 Ann. N. H., ser. 3, vol. xi., p. 93.
