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



species already described, but not only do they complete and 

 supplement the previous collections in the manner above 

 pointed out, but they greatly enrich it by adding many and 

 often much finer specimens than any that existed before. 

 First of all, they have added two species to the Tale collection 

 which were formerly only represented in that of the U. S. 

 National Museum. These are Cycadeoidea excelsa and C. 

 occidentalis. In the second place, the beautiful C. pulr 

 cherrima, of which the type is at the National Museum, is 

 now represented at Yale by at least one almost equally fine 

 specimen, while the great C. Je?ineyana, of which there were 

 only a few broken pieces, now numbers its representatives by 

 scores, some of them very fine trunks. The species which the 

 new accessions have perhaps most richly endowed is the rare 

 C. Wellsii, to which three or four huge and superb trunks are 

 now added. Every species known from the Black Hills is now 

 represented in the Yale collection, which was not previously 

 the case, and it is safe to say that that collection constitutes 

 the largest and finest assemblage of fossil cycadean trunks in 

 the world. 



Besides the specimens from the Black Hills, the Yale 

 Museum possesses two specimens from the Jurassic cycad bed 

 of the Freezeout Hills of Wyoming, treated by me in the 

 paper above cited in the Proceedings of the Washington 

 Academy of Sciences, and still further illustrated in the 

 Twentieth Annual Report of the U. S. Geological Survey. 

 These are Nos. 127 (Cycadella jReedii) and 128 (C. Beecher- 

 iana), for the completion of which Prof. Wilbur C. Knight 

 of the University of Wyoming, at my suggestion, has given 

 to Yale the complementary fragment, No. 500.54, of his much 

 larger collection from the same bed. There have also been 

 discovered among the forgotten collections in the Yale Museum 

 two fragments of cycads from the Iron Ore Clays of Maryland. 

 When these trunks were refound, Professor Marsh at once 

 remembered that he had secured them in 1867, from Mr. 

 Philip Tyson, the original discoverer of cycads in Mainland. 

 I have examined these specimens, and find them both to belong 

 to the predominant species of that region, Cycadeoidea mary- 

 landiea. They bear the numbers 729 and 730. 



There have also now been found in the Yale Museum 

 collections, 7 specimens of cycadean trunks from the original 

 Purbeck forest beds of the Isle of Portland, that overlie the 

 Portland stone. These are in two lots. The first consists of 

 a single specimen, the gift of Dr. Gideon Mantell to Prof. 

 Benjamin Silliman shortly after the attention of paleobotanists 

 had been called to these objects, so long known to quarrymen 

 as " crow's nests." It bears Mantell's label, Mantellia nidi-
