9. Forbes a sort of Rotation at bottom of sea in marine animals

 on widest ranges & living at greatest depths longest survivors Important.

 on migration of molluses; new species arrive at Isle of Man

11 Shuckard curious remarks on intermediate small [geese] with radiating affinities.

16 Forbes Ægean Report – p. 145 gregarious species not gregarious in Ægean species now dwarfs formerly larger.

152 Shells of same species smaller in W. Mediterranean then in East.

154 In each zone of depth the species have their maximum in that zone with few stragglers from other zones.

171 The species which range far in depth range far horizontally or have representative species in distant points

173 – increase of shells alters nature bottom & so & from other causes species change.

173 on individual maximum in depth; one species replace each other thus, if I understand rightly [Wyle] table given of illustration: together they tend to make a band of equal thickness; all this refers to the meeting of two species on the borders of their range in depth.

Will it illustrate changes in time? For if so it shows that the new species is an offset from that existing old one. Probably not only fully occupies economy of nature.

174  Genera have in same zones their maximums of development, showing that same constitution runs through many species.

175 Glacial theory, representative species of northern forms in depths of Mediterranean; I think identicalspecies in depths trend Great Britain.

175 on rarity producing extinction; & on species formerly rare now common

177 Littona zone richest & wd leave fewest fossils in formations.

26 Rogers Palæozoic the top of Coal, 30,000 ft thick – divided into 48 formations

p. 33-4 Shells common to Cretaceous & recent & some representatives – "those with greatest geograph. range have greatest vertical range" – It ought to be those which have lasted longest, have ranged furthest. It wd be opposed to my theory that all wide ranges shd change.
