fig. 11, Bigenerina nodosaria (not Clavulina, n. sp.); fig. 12, Pul- 
vinulina elegans (not Rotalia, u. sp.) ; fig. 18, Planorbulina Haidin- 
geri (not Rotalia, n. sp.); fig. 14, Rotalia Beccarit (not Rosalina, 
n. sp.); and fig. 20 is a Polystomella, near some South American and 
West Indian forms, and not a new species of Amphistegina. Dr. 
Karrer met with no Miliole in his samples of the deposit; but T'rz- 
loculina is noted in the appendix to Mr. Heaphy’s memoir above- 
mentioned ; and Rotalia Schroeteriana and Nodosaria Raphanistrum, 
also included in that list, may be added to Dr. Karrer’s, which, if 
named on the same plan, would comprise— 
1. Foraminifers that Dr. Karrer met with, but has not figured :— 
Nodosaria spinicosta (?). 
Cristellaria rotulata. 
Cr. cultrata. 
2. Figured forms :— 
Uvigerina pygmea. 
Polymorphina lactea. 
Globigerina bulloides (rare). 
Dentalina communis; fig. 1. 
Vaginulina Legumen; figs. 2 and 4. 
Lingulina costata; fig. 3. 
Cristellaria Cassis; fig. 5, 
Cr. Vortex ; fig. 6. 
Textularia agelutinans; figs. 7 and 8. 
Lituola globigeriniformis ; fig. 9. 
Orbitoides Mantelli; figs. 10 and 21. 
Bigenerina nodosaria; fig. 11. 
Pulvinulina elegans ; fig. 12. 
Planorbulina Haidingeri; fig. 15. 
Rotalia Beccarii ; fig. 14. 
Polystomella macella ; figs. 15 and 16, 
Nonionina wmbilicata ; fig. 17. 
Amphistegina vulgaris; figs. 18 and 19. 
Polystomella, sp. (?); fig. 20. 
Looked at in this light, these little fossils from New Zealand will 
be seen to be, for the most part, very closely allied to Foraminifera 
now living, in warm seas, at depths of about thirty to fifty fathoms 
and more; and any peculiarity of facies they may possess, scarcely 
gives them even swbvarietal characteristics. Lingulina costata, and 
the Orbitoides (which we think should be referred to O. Mantel), 
are well known in Miocene strata; most of the others range 
throughout the later Tertiary formations, and still exist—T. R. J.

pe a recent meeting of the Academy of Sciences, Paris, a letter was 
received from M. Dewalque, of Brussels, ‘ On the Distribution 
of Mineral Springs in Belgium. ‘The author having made an excur- 
sion in the neighbourhood of Liége, in company of M. Ch. Ste.-Claire 
Deville, this geologist remarked to M. Dewalque that the thermal 
spring of Chaude-fontaine and the acidulated ferruginous springs 
of Spa and Malmédy lay upon the same straight line, a fact which 
appeared to indicate a line of dislocation. Following up the sub- 
ject, M. Dewalque now addresses to the Academy details concerning 
seven of these mineral springs, giving the direction in which they
