verging toward a common base ; no basal bracts are visible, but there is a distinct 

 depression in the shale which may indicate the position of the enveloping bracts. The 

 leaves gradually taper towards the apex : the actual termination is seen in one 

 leaf only and has a rounded contour. The lamina is about 3-4 mm. broad and 1 2 cm. 

 long, and there appear to be approximately eight veins in a leaf 4 mm. wide, in addition to 

 traces of interstitial veins. The species of Phoenicopsis nearest to the Culgower type is 

 P. angustifolia Heer, recorded from the Jurassic of Siberia, from China by Krasser,* 

 by Nathorst t from the New Siberian Islands, and by myself from Turkestan.! Heer's 

 species P. speciosa is another similar type.§ P. Gunni differs from P. angustifolia in 

 the rather narrower leaves and the presence of interstitial veins.

 Araucarites Milleri sp. nov. (PI. V. figs. 97, 98, 102.) 



Despite the imperfection of the material, I venture to refer the Araucarian cone- 

 scales shown in figs. 97, 98, 102 to a new species, A. Milleri, named after Hugh 

 Miller, who recognised many years ago the presence in the Sutherland beds of Conifers 

 agreeing in the habit of the foliage-shoots with recent species of Araucaria. The cone- 

 scales are characterised by a broad membranous wing, the presence of a distal spinous 

 process and a single seed-cavity. They have the same form as those of Araucaria 

 excelsa and other species of the Eutacta division of the genus. Fig. 98, PI. V., represents 

 one of the largest and best-preserved examples, 3 cm. long, with a rounded and some- 

 what ragged distal border prolonged into a terminal spine. The actual base of the 

 scale is not preserved. A shallow depression shows the shape of the seed, the vascular 

 supply of which (or possibly the resin-canals accompanying the vascular strands) 

 is represented by several yellow lines converging slightly towards the base and giving 

 off branches into the adjacent parts of the scale. Fig. 102 shows the distal spine in a 

 more complete form, and fig. 97 represents a smaller scale with strands on the floor of 

 the seed-cavity. 



Among the numerous examples of Araucarian cone-scales described from Jurassic and 

 Lower Cretaceous rocks there are none which are undoubtedly identical with the present 

 species, though several exhibit a close resemblance. From the Jurassic of England we 

 have Araucarites Phillipsi Carr., A. Brodii Carr., A. sphserocarpa Carr., as examples 

 of similar scales.|| Other allied types are A. cutchensis Feist. If from India and the 

 Antarctic regions,** Araucarites sp. from the Jurassic of Germany ,tt A. wyomingensis
