parent bird if collectors are allowed to destroy all her eggs ? 
For this is what in many cases they are doing to-day, and 
not only with the cuckoo, but with other birds. Is it not 
time to amend the law? 
NIGERIAN FORAMINIFERA. 
Bulletin No. 3 of the Geological Survey of Nigeria contains 
a report on ‘ Foraminifera from the Eocene Clay of Nigeria ' 
by E. Heron-Alien, F.R.S., and A. Earland, from which we 
learn that ‘ the sample, limited as it was, has furnished a few 
very distinctive and interesting forms, one of which, at least, 
Virgulina schreibersiana var. marginata may safely be described 
as new to science. The two Miliolids, M. sulcifera Roemer 
and M. bicarinella Reuss. are interesting, as not having been 
recorded again since they were first described and figured by 
their authors. The occurrence of Peneroplis carinatus 
d’Orbigny, which we recorded from the Eocene of Selsey 
Bill, is noteworthy, as also is the fact that the only repre- 
sentative of Bulimina is found in B. fusiformis Williamson, 
which must be abundant in the deposit. We record also the 
typically cold-water species Globigerina pachy derma Ehrenb., 
which also occurred at Selsey. The Nonioninae are interesting 
but involved, the species running into one another and ex- 
hibiting an extraordinary tendency to limbation of the 
sutures ; this tendency is noticeable also in other species, 
notably in Pulvinulina brongniartii (d’Orb.) and Bolivina 
textilarioides d’Orb.’ It seems remarkable that specific 
identification can be established between species which are 
so far separated geographically as Selsey Bill and Nigeria. 
GAULT AND RED CHALK. 
In a paper on the ‘ Overlap of the Upper Gault and on the 
Red Chalk,’ in the Geological Magazine, No. 695, in referring 
to Yorkshire and Lincolnshire, Dr. F. L. Kitchin and Mr. J. 
Pringle states : ‘ In Yorkshire the extension of the overlap 
of the “ Red Chalk ” on to older rocks is well known. At 
North Ferriby we have examined the relation of the trans- 
gressive beds to the substrata, and find that they there rest 
upon a clay belonging either to a basal Kimmeridge or Upper 
Corallian zone. At South Cave the “ Red Chalk ” probably 
lies on Corallian clay. At that locality Inoceramus sulcatus 
and Ammonites rostratus were recorded by Hill, who also 
noted the occurrence of Inoceramus. sulcatus at Wharram 
Grange. At Market Weighton, where the base of the Red 
Rock is markedly conglomeratic, it can be seen resting on 
the clays and ironstones of the Lower Lias. Mr. T. Sheppard 
kindly drew our attention to a newly made opening at the 
Rifle Butts in the Goodmanham Valley, and accompanied 
one of us on a visit to this locality. It was observed here 
1922 Aug.-Sept.
