1898] NOTES AND COMMENTS 'il'6 



graphic note, a suniiuary of results on the zoohjgical and zonal dis- 

 tribution, and a complete distribution table showing the occurrences 

 of the Foraminifera throughout the whole of the Folkestone Gault 

 at intervals of 5 feet. Mr Chapman has also found time to issue a 

 note on the forms found in the Hartwell clay {rroc. Geul. A>isoc.^ 

 July 1897); to show that the proper specific name of Saccammina 

 cartcri is really "fnsiilinafo7"mi^" of M'Coy, 1849 {Aitnah Mag. 

 Nat. Hist., March 1898); to join with Prof. Ivupert Jones in a 

 masterly resume of the whole of that singular genus Folymorfliina 

 {Journ. Linncan Soc. Zool. 1896) ; and to write several other papers 

 of considerable interest. He also undertook the section Protozoa 

 in the Zoological Eecord, to which his contribution in conjunc- 

 tion with Dr Frazer Hume appeared in the volume for 1895. 



Dr E, M. Bagg has given us a detailed description of the 

 Foraminifera in the Tertiary and Pleistocene beds of tlie Middle 

 Atlantic Slope {Bull. Avicr. Paleont, vol. ii., Ithaca, N.Y,, March 

 1898). American forms being so little known, this paper is the 

 more valuable, and we hope Mr Bagg will dip further into the 

 subject. The chief things to notice are a new S'piropleda, S. c/arki,. 

 and SjnriJ/ina orhicidaris. Fifty-seven forms are enumerated. 



Dr Carlo Fornasini continues his descriptive work, and among 

 his papers are two in the Rendiconti R. Accad. Sci. 1st. Bologna, 1897, 

 which discuss the work of J. B. Beccari and 0. G. Costa respectively. 



Mr J. J. Lister deals in the Proceedings of the Royal Society,. 

 1897, with "a possible explanation of the quinqueloculine arrange- 

 ment of the chambers in the young of the microspheric forms of 

 Triloctdina and Biloculina!' As is well known from the researches 

 of Mr Schluniberger, the young of the megalospheric form of Biloculina 

 commences with a large chamber, the later chambers being disposed 

 on either side of a single axis ; while in the microspheric forms of 

 the same genus, the young begins with a small chamber, and the 

 later chambers are disposed on a rotating axis, that is to say, the 

 plane dividing any single chamber symmetrically is not identical 

 with the corresponding plane of the preceding chamber, but directed 

 at a definite angle to it. It appears possible that, in the first case,, 

 the reproduction is asexual and in the latter sexual, but Mr Lister 

 confines himself to suggestion for the present {vide ante, p. 58). 



Finally, Dr Ludwig Rhumbler, of Gottingen, has a series of notes 

 on the double-shelled Foraminifera, on reproduction and on struc- 

 tural peculiarities of Protozoa generally, which he published in the 

 Biologisckes CentralUatt early this year.
