JURASSIC CYCADS FROM WYOMING. 179 



The plant is not unlike those from the Jurassic, called by Heer 

 Elatides, and may be compared with E. falcata," but the leaves are larger 

 than those of that plant. It may be fittingly named from its discoverer 

 Sequoia Fairhanksi. 



JURASSIC CYCADS FROM WYOMING. 



Since the appearance of the first paper of this series, in which all the 

 Jurassic cycads from the Freezeout Hills of Wyoming that were known to 

 me at that time were described and figured,* two additional invoices of 

 material from the same restricted bed have been sent to the National 

 Museum by Professor Knight under the same conditions as those relating 

 to the first invoice. The former of these invoices consists of the collection 

 made by me on the occasion of my visit to the locality in 1899, an account 

 of which is given in the first paper, but the full treatment of the collection 

 could not be then made, as it was necessary to go to press with the paper 

 before the collection could be studied (see p. .387 of that paper). As soon 

 as I found time, however, I had the collection unpacked and the speci- 

 mens numbered according to Professor Knight's instructions. These were 

 to continue the numbering from the last number of the first invoice as far 

 as the specimens extended. The numbering was on the basis of 500, and 

 the first invoice included Nos. 500.1 to 500.87, although these numbers 

 included several specimens of fossil wood and one bone taken from the 

 same bed, the latter not sent with the cycads. 



Only a few large specimens or nearly complete trunks were found by 

 me and the collection consisted chiefly of fragments, many of them quite 

 small, some of them mere chips or splinters. I was careful to save almost 

 everything that could be seen certainly to belong to a cycadean trunk, in 

 the hope that, coming as they did from the same bed, a few of them might 

 be found to be the missing parts of incomplete trunks in the first invoice. 

 In this, as will be seen, I was not mistaken, although the result is not so 

 satisfactory as might perhaps have been expected. The number of such 

 small fragments was very large, and when they were all numbered they 

 extended the list from No. 500.88 to 500.687, including therefore, by a 

 curious coincidence, just 600 specimens.
