W. Carruthers — British Fossil Coniferce. 3 



recorded from the Kimmeridge clay, and as it is a well marked, 

 though probably a young cone, it seemed to be desirable to figure it. 

 It is 10 lines long, and 11 lines broad. It is in the collection of the 

 British Museum. 



II. Araucakites, linger. 



Since the publication of my paper on Fossil Araucarian Cones 

 (Geol. Mag., Vol, iii. p. 249), I have had the opportunity of examin- 

 ing the as yet unique specimen of Araucarites Pippingfordensis, 

 Carr., with which I was then acquainted only from Fitton's accurate 

 figure. This examination has confirmed the opinion I then formed 

 that this fossil was nearly allied to A. sphcerocarpus, Carr., and that 

 they both belonged to the section represented by the Australian 

 species, which, from their peculiarities, have been separated from the 

 American species by some authors as a distinct genus with the 

 name Eutacta. I may also mention here that unwittingly I intro- 

 duced an i into the specific name, which should not be there, follow- 

 ing the erroneous spelling of Unger's Synopsis. 



I have now to add two additional species belonging to this genus, 

 both from Oolitic rocks ; founded principally on the detached scales 

 which occur, the one in great abundance at Stonesfield, and the 

 other somewhat more rarely in Yorkshire. 



1. Aeatjcaeites Bkodiei, sp. nov. Plate II. Figs. 1-6. 



Scales from the centre of the cone cuneate, gradually tapering 

 towards the narrow base of attachment to the axis, composed of two 

 portions, each terminating at its free apex in a short spinous process, 

 the lower and larger portion very broad and membranous, the upper 

 portion narrower and somewhat parallel-sided, supporting between 

 them a single ovoid seed. 



Locality. — From the Stonesfield Slate of Stonesfield. 



I first noticed this species when examining the large collection of 

 Stonesfield slate fossils in the Oxford Museum, and part of my illus- 

 trations are from a specimen which Professor Phillips permitted 

 me to have the loan of from his private collection. The scales are 

 scattered over the surface of the slate, exhibiting, as is the case with 

 the fossils of this bed, only casts of the organism slightly coloured 

 with the remains of the mineral carbon into which they were con- 

 verted. In some specimens the cast of the three parts of the scale 

 are clearly seen, viz., the upper and under scales and the seed. The 

 scales are from eight to eleven lines long, and from six to twelve 

 lines broad at the widest parts. They present the double apex 

 characteristic of the section Eutacta. In the collection of the Eev. 

 P. B. Brodie I have found Ihe cast of the lower portion of a cone, 

 with an inch and a half of the supporting branch, marked by the scars 

 of the leaves. This fragment exhibits the attachment of eight scales, 

 and clearly establishes the true nature of the detached specimens. 

 This is the more important, as the scales have been described as 

 complete organisms by M. Pomel/ who has detected them in the
