Madoura, and other parts of the Dutch East Indies, with which the New He- 

 brides marine area was most probably connected when these fossiliferous 

 beach and shallow-water deposits were laid down. The occurrence of a new 

 species of Cycloclypeus in the New Hebrides rocks further emphasises the 

 fact that certain genera and species of even such lowly forms as protozoa have 

 been more or less restricted in their geographical distribution from their ear- 

 liest geological appearance until recent times ; for this part of the world af- 

 forded us the earliest dredged specimens of Cycloclypeus^ and with the ex- 

 ception of an Arabian fossil species, the Tertiary examples seem to be restric- 

 ted to this area also. — 3) On the Occurrence of a Bed of Fossiliferous Tuflf 

 and Lavas between the Silurian and Middle Devonian at Cavan, Yass,N.S.W., 

 similar in Age and Character to the Snowy River Porphyries of Victoria. By 

 A. J. Shearsby. (Communicated by W. S. Dun). — On the left bank ot the 

 Murrumbidgee, about half a mile below Boambolo Ford, a splendid anticlinal 

 fold was met with. This may be known as the Glenbower Anticline. It is 

 about 150 feet high, the summit being of porphyritic tuff, overlying a band of 

 quartzite which in turn covers the following strata in descending order — 

 tufaceous limestone, thin layers of sandstone, shale and limestone, thick hard 

 compact limestone, thin bands of sandstone, shale and limestone, hard com- 

 pact limestone, sandstone showing current bedding, hard compact limestone, 

 and finally, at the riverlevel , sandstone. The dip of these strata is about 

 30° S. Fossils of Upper Silurian Age are abundant in situ, and comprise, 

 among others, Favosites gothlandica^ Heliolites^ Stromatopora^ Cyathophyllum 

 (fasciculate), Syringopora (dendroid), Favosites^ Amplexus^ Alveolites^ Atrypa 

 reticularis Linn., Atrypa sp., Orthis^ Chonetes^ Tryplasma sp., Crinoid stems, 

 and Trilobites of the genera Cromus and Encrinurus etc. — About two miles 

 distant from the Glenbower Anticline, in a north-west direction, is Clear 

 Hill, about 300 feet high, made up of porphyry at the base like that over- 

 lying the Silurian shales, and above this, in succession, shale (about 200 feet 

 thick), quartzite, chert-like felsitic or trachytic tuff (30 — 40 feet), shale 

 (about 150 feet), and finally limestone to the crown of the hill. The strata 

 are inclined at an angle of about 50 ° S.W. The limestone on the summit 

 contains fossils of Middle Devonian Age, such as Diphyllum genimiforme^ 

 Eth. fil., Stromatopora, Cystiphyllum australicum Eth. fll., Favosites^ Cyatho- 

 phyllum^ Chaetetes\^\ Alveolites^ Desmidopora^ Syringopora^ Leptaena^ Spiri- 

 fera Yassensis De Kon etc. — The intervening country includes a narrow 

 strip of shale with thin bands of limestone containing Upper Silurian 

 fossils, the whole mass being very highly contorted and covered here and 

 there with masses of the porphyritic tuff already mentioned as capping 

 the anticline. At about one mile below the anticline the shale disappears 

 and is followed by an alluvial river flat, which ends at the foot of Clear 

 Hill. — Taking into account the macroscopic resemblance of the porphy- 

 ries at Cavan to the Snowy River Porphyries of Victoria, the distribution 

 of the latter (from the Victorian Border to Mount Kosciusko), and the pro- 

 bability that further search will reveal outcrops of the same beds over 

 the country between Mount Kosciusko and Yass, the opinion is expressed 

 that the beds are in direct communication, since »the age of the Snowy River 

 Porphyries in fixed by the Silurian sediments which are inferior to them, 

 and the Middle Devonian marine limestone which, for instance, at Gelantipy, 

 rest upon them« (Howitt). — Mr. Edgair R.Waite reported that a Leopard
