None of the specimens in the second and third invoices were referred 

 to this species. The types were not in my hands, benig at the \ ale 

 University Museum. They consist of No. 128 of that museum and No. 

 500 54 of the Museum of the University of Wyoming, which I found to 

 be a complement of the former, and which, on this account. Professor 

 Knight gave to Yale to complete the specimen there. Although the 

 species was carefully described and fully figured, ami I have a distmct 

 visual impression of its appearance, it is not impossible that if the spec- 

 imens had been before me I should have provisionally referred to it some 

 of the more aberrant forms. 



Cycadella wyomingensis Ward. 

 PL XLVI. 

 1900 Cycadella wyomn^gensis Ward: Proc. Wash. Acad. Sci., Vol. I p. 266 pi. xvii; 

 Twentieth Ann. Rep. U. S. Geol. Surv., 1898-99, Pt. II, p. 39., pi. Ixxix-xc. 

 Three large specimens and many smaller ones in the last two invoices 

 are referable either with certainty or with considerable probability to 

 this species One of the large ones. No. 500.88, consists of one large piece 

 weighing 6 8 kg. and two smaller ones of nearly equal size weighing 

 together 1 9 kg., all bearing the same number, and making a total weight 

 of 8 7 kg These all fit perfectly together and form more than three- 

 fourths of a very handsome trunk. The basal portion only was wanting, 

 but the greater part of it was found under two other numbers, viz, Nos. 

 500 513 and 500.525, which were first found to fit each other and after- 

 wards to fit the lost part of the large trunk. No. 500.513 weighs 1 72 kg 

 while No. 500.525 is a small piece weighing 177 grammes. P^^^ing all 

 these pieces together we have a nearly complete trunk weighing 10.6 kg. 

 The onlv part lacking is a small notch on one side of the base, which none 

 of the fragments in the collection would fit into. Thus compMed this 

 trunk is very nearlv the same size as the type specimen ^o. 500.15 and 

 resembles it in many respects. It is, however, rather more flattened, 

 largest in the middle, where the major diameter is 24 cm. and the minor 

 13 cm., giving a girth of 59 cm. It stands 36 cm. high.
