not abundant ; among them is a hornblende schist containing abun- 

 dance of tourmaline. The sandstones, some of which are of very- 

 large size, belong chiefly to the Carboniferous series, and, as a rule, 

 are unfossiliferous. Two blocks of fossiliferous sandstone have been 

 identified with the sandstone of the Lower Neocomian series in 

 Lincolnshire. Of the limestones there are a great number of blocks 

 of a hard grey crystalline limestone of the Carboniferous series 

 containing some very perfect specimens of Foraminifera ; and 

 two specimens from the Ehsetic beds, which are of peculiar interest 

 if, as it is said, the Ebgetic beds do not now come to the surface any- 

 where in the North of England. The greater number, however, of 

 the limestones belong to the Jurassic series ; there are also many 

 lumps of very hard chalk which have been identified with the hard 

 chalk of Cambridgeshire. The microscopic sections of the Chalky 

 Boulder-clay show that amid grains of quartz, sand, etc., there are a 

 great number of minute Foraminifera still wonderfully well pre- 

 served. The way in which the Chalky Boulder-clay and the gi'avels 

 lie was well shown in a railway-cutting near Dunmow some sbort 

 time ago, and happily a small photograph of the section was taken 

 at the time, for that part of the cutting has now been covered in. 

 It is possible that this attempt at classifying and describing the rocks 

 of the drift may be of some assistance to those who are considering 

 the general question of the glacial drift. 



3. "On Tertiary Cyclostomatous Bryozoa from New Zealand." By 

 Arthur W. Waters, Esq., F.G.S. 



The Cyclostomata noticed in this paper were from the same 

 collections as the Chilostoraata described in the last volume of the 

 Quarterly Journal, and this part was kept back a short time, in the 

 hope that the publication of the Eeport of the "Challenger" ex- 

 pedition might throw some light upon this unsatisfactory suborder ; 

 but the results are very disappointing in this respect, as only thirty- 

 three species are recorded, and these for the most part well known 

 and common ones. 



It was proposed to subdivide the Cyclostomata into two sections, 

 namely : — 1, those in which the surface of the zoarium is to a 

 considerable extent formed of the lateral walls of the zooecia, as 

 EntalopTiora, etc. ; and 2, those in which the zooecia or cancelli open 

 for the most part at right angles to the axis, or surface of the zoarium, 

 or subcolony, of which Heteropora and LicJienopora are typical. 



The author recorded the preservation of the extremely delicate 

 and fragile rays or " hair-like teeth " in the interior of the fossil 

 EntalopTiora intricaria. 



Out of the twenty-eight species or varieties eighteen are known 

 living, and this part of the collection agrees with the former in indi- 

 cating that it is comparatively recent. The number of these fossil 

 Bryozoa is now brought up to 106. The new species described 

 by the author were : — EntalopJiora wanganuiensis, Tuhulipora tiibipora, 

 Lichenopora wanganuiensis, Beptocavea aspera, Heteropora napierensis, 

 and CrassoTiornera waipukurensis ; and he also noted a new variety, 

 perangusta, of Diastopora sarniensis.
