petrified wood of Darntnara, which was collected iu Amuri, the 

 section of which (PI. XXIX., fig. 13) is shown 350 times en- 

 larged. The tracheae are correspondingly thicker than in the 

 section of Araucaria previously described; the walls of the 

 tracheae are thickened a good deal. The core-streaks are 

 numerous and very fine. Fig. 14 represents the section 

 lying between the radii of a circle, also enlsirged 350 times. 

 The spots are especially remai-kable ; they ai"e flattened, stand 

 in from one to three rows, and are in the form of a polyhedron. 

 The tangent section ifig. 15), equally enlai-ged, shows the oval 

 liis-eUiptical crosscuts of the cells of the core-streaks, which 

 cells are joined together by from 5 to 15. 



I believe I ought to ascribe to the above species the woo<l 

 just described, which I name after Sir Richaed Owen, in con- 

 sequence of his merits as regards the palaeontology of New 

 Zealand.

The leaf (fig. 20) shows all the characteristics of the pre- 

 vious species, with the only difference that at the somewhat 

 pointed base a median nerve appears, which, however, disap- 

 pears a short distance from the point. I beheve I am coiTect 

 in ascribing this leaf to Dammara, but it belongs to a distinct 

 species. My supposition of a second species of Dammara in tht- 

 Shag Point strata was also strengthened by the existence of a 

 cone-scale (fig. 21), which may be distinguished from the pre- 

 vious species by the following characteristics : The scale is 

 considerably larger — viz., 37mm. wide and 42mm. long — and 

 more rounded and wedge-shaped. This scale agrees best with 

 the broad cone-scale of Dammara ovata, Moore, in which also 

 large cones appear.
