were obtained. For convenience of reference the localities will be num- 

 bered and the reference of the different fossils to them will be by these 

 numbers. In the case of some collections the specimens were counted. 

 In other cases the number must be indicated in some other wa_y and 

 estimated. The following are the localities: 



Locality No. 1. — This is Todd's first discovered locality. It is on the east 

 side of Buck Mountain, 300 feet below the top. Of Mr. Todd's collections only 3 

 specimens are among those available for examination. From this locality Mr. 

 Storrs subsequently collected, in September, 1897, about 50 specimens, and still 

 later Professor Ward and Mr. Storrs obtained 25 specimens. 



Locality No. 2. — This locality occurs on Thompson Creek, at the northern 

 foot of Buck Mountain, near the dam of the Day Hydraulic Gold Mining Company. 

 From this locality Mr. Storrs, in the fall of 1896, obtained a small collection of about 

 30 specimens, and on Jime 30, 1897, he made here a somewhat larger collection of 

 about 50 specimens. In September, 1897, Mr. Storrs obtained from the same 

 locality about 70 specimens. These plants come from the lower slate bed, bed 

 No. 1, mentioned above. Some of the following collections, made later by Pro- 

 fessor Ward and Mr. Storrs in this region, may have been obtained from the spots 

 at which Mr. Storrs had previously collected. 



Locality No. 3. — This is in a ravine. at the foot of Buck Mountain on the right 

 bank of Thompson Creek immediately below the Day hydraulic dam. Onlj' 1 

 specimen was collected here by Mr. Storrs, on September 12, 1899. 



Locality No. 4- — This is 200 yards farther down, or to the southeast of locality 

 No. 3, in a ledge on the right bank of the same stream. Here, on September 14, 

 1899, Professor Ward collected nearly 100 specimens. 



Locality No. 6. — This is on the left bank of Thompson Creek, on the western 

 slope of a ravine coming from the south and 300 yards below the Day hydrauHc 

 dam. Professor Ward collected here, on September 12, 1899, 15 specimens. 



Locality No. 6. — This is 100 yards southwest of locality No. 5, in a low ledo^e 

 on the left bank of Thompson Creek. Professor Ward collected here, on September 

 14, 1899, about 40 specimens and small fragments. 



Locality No. 7. — This occurs in the bed of Thompson Creek, in the rio-ht 

 bank, beginning nearly opposite to locality No. 6, but extending some 50 feet 

 along the stream. Professor Ward and Mr. Storrs collected here, September 12-14, 

 1899, several hundred fine specimens. This is decidedly the largest collection 

 made. It much surpasses the other collections in the size of the specimens and 

 in the perfection of the plants. The plants collected here and at locaHty No. 6, 

 come from the slates above the conglomerate. 



Locality No. 8. — This occurs 200 yards east of locahty No. 2. Mr. Storrs 

 collected here, in September, 1897, about 10 specimens." 



a He seems to have exhausted the locahty, as no plants could be found there, even by him, in 1899. He 

 said that his specimens came from one bowlder which he broke up. — L. F. W.
