210 Prof. T. Rupert Jones — On Swiss Jurassic Foraminifera. 



Figs. 1-10 are already named NodosarincB (fig. 10 is intermediate 

 to figs. 9 and 10, iii., pi. 1); figs. 11 and 12 {^Oph. carinatum) repre- 

 sent a Spiroloculine Miliola. 



B. Bathonian : Middle Brown Jura. Parkinsoni-clays : e of 

 Quenstedt. a. "Prom Fuetzen, Baden, h. From Bargen, Canton 

 Schaffhausen. Pp. 17-19 ; pi. 2, iii., figs. 1-11. 



Lagena 1 ; Cornuspirse 3 ; Nodosarise 2 ; Vaginulinse 2 ; Cristel- 

 lariae 4 ; Ophthalmidium 1. 



Lagena ParMnsoni (fig. 1) is L. glohosa. Cornuspira Eichhergensis 

 (fig. 2) is a Spirillina, possibly the same as fig. 3, i., pi. 2. Figs. 

 3 and 4 {Cornusp. elliptica et gracilis) appear to be varieties, orbicu- 

 lar and elliptical, of Trochammina incerta, though gracilis is said to 

 be transparent. Figs. 5-9 are common well-known JVbdosarina. 

 Figs. 10 and 11 (OpTi. Oheni) are Spiroloculine Milioloe. 



G. Callovian : Kelloway group : Upper Brown Jura. a. Lower 

 division. Macrocephalus-bed, from the Eichberg, near Achdorf, 

 Baden. Pp. 19-21 ; pi. 2, iv., figs. 1-14. Lagena 1 ; Cornuspirae 

 2 ; Vaginulinae 3 : Frondicularise 2 ; Cristellariae 8 ; Nonionina 1. 



Fig. 1 [Lag. minutissima) is the common little L. glohosa. Fig. 2 

 seems to be a Spirillina from the description (colourless, trans- 

 pai-ent) ; but it may prove to be a Cornuspira. The other so-called 

 Cornuspira will be a Trochammina, if its correlation with the fore- 

 going C. elliptica be correctly indicated. Figs. 3-13 are various 

 common Nodosarince, unnecessarily named afresh. Fig. 14 is not a 

 JVonionina, but probably a Planorhulina. 



b. Ornati-clay : Upper division of the Callovian stage : ^ of Quen- 

 stedt. Pp. 21-23 ; pi. 2, v., figs. 1-7. 



Lagena 1 ; Cornuspira 1 ; Dentalina 1 ; Frondicularia 1 ; Cris- 

 tellaria 1 ; Flabellina 1 ; Ophthalmidia 3. 



Cornusp. Biedermanni (fig. 1) is probably a true Cornuspira.^ The 

 JVodosarince (figs. 2-5) did not require new names. Fig. 6 (Oph. 

 carinatum) is a Spiroloculine, and fig. 7 [Oph. multiplex) a Quin- 

 queloculine Miliola. 



III. Upper or White Jura. A. Lower White Jura : Oxfordian. 



1. Birmenstorf-bed : Transversarius-zone (Oppel). a. From the 

 Eebberg of Birmenstorf, Baden, b. From the Eichberg. Pp. 

 24-33 ; pi. 3, figs. 1-50. 



Lagena 1 : Cornuspirae 3 ; Frondicularise 2 ; Nodosarias 3 ; Denta- 

 linas 3 ; Vaginulinae 9 ; Marginulinse 5 ; Cristellariae 12 ; Eobulina, 

 1 ; Nonionina 1 ; Globulina 1 ; Vulvulinse 3 ; Textilariaa 2 ; Ophthal- 

 midia, 6. 



Fig. 1 (Lagena Helvetica) is L. Icevis. Cornusp. Eichhergensis 

 (fig. 2) and C. concava (fig. 3) are orbicular and elliptical indi- 

 viduals of Trochammina incerta; C. gracilis is also mentioned, 

 which, according to its figure (pi. 2, iii., fig. 4), appears to be a 

 Trochammina, although it is said to be transparent (the thick edge, 

 however, is duller and yellow, p. 17). Figs. 4^38 are various 

 JVodosarince, each of which falls under some well-known name or 

 another. Nodosaria radicula and Dentalina communis respectively
