Specimen h. — This is an encrusting thalliis. very thin, oir- (tU 

 layer in thickness, spi-ead over the surface of a pliosphatic pchhle 

 from Jiorc ."5, 20(1 feet. The ek)ngate-rectanguhir cells are like those 

 of Lif/iofha/iinio/i rnniosnxinnnn. l)ut niuch larger. Thev spi'ead 

 far-wise over the surface, and the limiting plane of each succes- 

 sive growth is undulate or convex. In some respects it is allied to 

 Lithotliainiiion lichenoides, Ellis and Sol. sp., Avhich Foslie places 

 in his second section (Evanidae) of the suhgenus Eulithofhamnion. 

 The question here arises whether a form like L. raniosissiiin//// , wlien 

 attached to a rolling pehhlc, does not conform to its surroundings 

 and show a varietal mutation on account of the abnormal conditions 

 •of its existence.

This is a comparatively large fragment, subcylindrical, measur- 

 ing 11 X 5.5 mm. It cannot be referred to a branchlet of /.. ifn/iu- 

 ^issimum, since the succes.sive concentric layers of the growing 

 thallus are separated by narrow spaces, which show it to be per- 

 sistently encrusting; and what is more important, there arecircidar 

 depressions over the surface on the sunmiits of low monticules, 

 pointing to superficial conceptacles.

 Ohserrations. — This remarkable and easily indentifiable species 

 was figured and described by M. Schlumberger from the lower beds 

 at Muddy Creek, near Hamilton, where the Rev. W. Howchin found 

 it to be moderately common, ^t also occurs in Miocene strata in the 

 New Hebrides. It was only occasionally found in the present bores, 

 in strata identified as Janjukian by the general characters of its 

 facies. It here evidently persists into a higher horizon than that
