A collection of skulls and several hundred bones of Bhon occi-

The most important accession of many years was tlie collection of 

 several thousand specimens of Orestes St. John presented to the Mu- 

 seum by Frank Springer, to whom it was left upon the death of St. 

 John. The collection consists of a general collection of Devonian 

 invertebrates, but more important is his large and extremely valuable 

 collection of selachian fish i^emains, chiefly from the Carboniferous. 

 It contains numerous types and illustrated specimens described by 

 St. John in the Illinois reports, as well as a large amount of original 

 unstudied material. There is also included a large quantity of very 

 choice cestraciont fish material, much of it collected by Mr. Springer 

 from the Burlington limestone of Iowa, as well as two exceptionally 

 fine collections from the Keokuk limestone made by Dr. G. A. Wil- 

 liams and Lisbon A. Cox, which were purchased by Mr. Springer 

 and turned over to St. John, together Avith his own, for use in his 

 researches. Among other notable specimens in this collection men- 

 tion should be made of the type of Campodus {Agassizodus) varia- 

 hiJw (Newberry, J. S., Ohio Geol. Surv. Eep., pt. 2, vol. 2, p. 50, 

 1870) ; this rejDresents a complete dentition from the Coal Measures 

 of Kansas in a state of preservation such as has not been found 

 elsewhere. 



Another most notable accession was the residuary portion of the col- 

 lection of E. D. Lacoe, of Pittston, Pa., presented by his heirs. Be- 

 sides the fossil plants and invertebrates, which formed the bulk of 

 the accession of 10,000 specimens, it also contained several hundred 

 fish, reptilian, and amphibian remains. The Tertiary is represented 

 by specimens from the Green River and from Switzerland; Triassic
