[MATTHEW] A REVIEW OF THE LITTLE RIVER GROUP 103 



c. This is probably Hartt's Ko. 2, and is one of the most prolific 

 beds in the series. Wliere I iworked it the shale is of a dark colour 

 and very fissile and rather soft. It is, or rather, was, worn down to 

 the level of the beach, but I was able to follow it for twenty or thirty* 

 feet east and west. Sphenopteris marginala is very abundant, also 

 Neuropteris polymorphn. Besides these which were so common, I 

 found nearly all the plants mentioned in Ilartt's list. I remember 

 some excellently preserved specimens of Psilophyion glabrum and 

 Cordaites Rohhii. 



Then follow some small beds which showed occasionally after heavy 

 storms, by which some new spot was laid bare, from which I collected 

 several species, as Neuropieris polymorpha, Cordaites Rohbii, the two 

 Calamités, Sphenopteris marginata, Pinnularia dispalans, Psilophyton 

 elegans. P. glahrum, Cardiocarpon cornutum, and Sporangites acumin- 

 ata, and other fruits. 



d. About half way down the beach, between high and low water 

 mark I found a greenish shale which contained a beautiful frond of 

 Pecopteris. We thought the fern new at the time, but Dr. White 

 says it has been described; I have forgotten the name of the 

 species but it is a Pecopteris. The l3ed is only two or three inches 

 thick. It is the only place where I found this fern. Megalopteris 

 Dawsoni is, I think, between c and d, and not far from d. 



e. A few feet above the last bed (d), that is down the beach, and 

 nearer low water, there is a somewhat hard layer containing very large 

 specimens of Cordaites Rohhii in great abundance. This bed also 

 contains Neuropteris polymorpha. Calamités, sp. and Alethopteris 

 discrepans. 



f. Near low-water mark there are some beds worn to near the 

 beach level, rather hard and not very fissile, which break somewhat 

 irregularly, and show slicken-sided surfaces, that contain very good 

 specimens of Alethopteris, usually a single large leaf. 



Of this section Mr. Wilson writes me that he has had to depend on 

 his raiKiory, as he made no exact record of the species from each bed 

 when collecting. 



On comparing the two sections, Hartt's and Wilson's, there seems 

 no certainty that Mr. Wilson collected from the upper sub-fauna, except 

 the specimens he may have taken from the bed /; and except the Ale- 

 thopteris from that bed, the species he cites from his upper beds are 

 such as have a wide range and are not necessarily of the upper sub- 

 fauna.
