L. F. Ward — Fossil Cycads in the Yale Museum. 331 



formis Brongniart, with a reference to the figure in his 

 Wonders of Geology, 1839, p. 365, fig. 70 (or is it to his 

 Medals of Creation, in the later editions of which, but not in 

 the earlier, the same figure occurs?). As the Mantellianidi- 

 formis of Brongniart is the Cycadeoidea megalophylla of 

 Buckland, it is evident that Dr. Mantell supposed the speci- 

 men to belong to this species, but it does not agree with .his 

 own figure, and seems rather to represent the small-scarred 

 species, Cycadeoidea micropkylla Buckland. This specimen 

 has been numbered 732 of the Yale collection. 



The other lot consists of 6 specimens which were received 

 on Sept. 24, 1898, from Mr, A. N. Leeds, the collector and 

 donor. They have now been given the numbers 733-738. 

 Three of them (Nos. 733-735) belong without doubt to 

 Cycadeoidea microphylla Buckland. No. 736 probably be- 

 longs to the same species. Nos. 737 and 738 have the large 

 scars of C. megalophylla, and undoubtedly represent that 

 species. 



I made my fourth visit to the Yale Museum in May, 1900, 

 and commenced work on the new material on the third of that 

 month. My first work was to identify as many of the 

 specimens as possible with previously described species. In 

 many cases this was easy of accomplishment, but in dealing 

 with the immense number of fragments and the imperfect, 

 immature, dwarf, and depauperate specimens that necessarily 

 accompany a complete collection, and which, in spite of the 

 trouble they give, ought always to be collected, doubts con- 

 stantly arise and cannot be removed. In the list which follows 

 I have expressed such doubts by interrogation marks, and they 

 are taken to indicate the tentative and incomplete character of 

 the work. The future will doubtless greatly change matters 

 in these respects, and the reader is asked to make due allow- 

 ance for the unsettled state of our knowledge of these objects. 

 A mere list of species with numbers attached is admitted to 

 be unattractive reading, but it nevertheless affords an idea of 

 the relative abundance of the species, and will have value as a 

 guide or catalogue of the collection for any who may wish to 

 study or examine it. An alphabetical arrangement of the 

 species will probably prove more convenient than any attempt 

 at systematic classification. The following are the 29 species 

 thus far known, with the specimens in the Yale collection that 

 have been assigned to each : 



Cycadeoidea aspera, No. 104. 

 Cycadeoidea cicatricula, No. 118. 



Cycadeoidea Colei, Nos. 12, 20, 25 ?, 28 ?, 48, 52 ?, 57, 68, 80 ?, 

 224 ?, 240?, 246 ?, 291, 321, 433, 444, 476 ?, 539.
