6 Thirty-fourth Annual Report of the 



specimens have been purchased. The additions to the Insect collections 

 by Mr. Lintner will be found in a special list. 



To the collections in Mineralogy, Geology and Palaeontology, there 

 have been added by the donation of nine contributors, twenty-six speci- 

 mens ; and by purchase, thirty-five specimens. 



A special collection of Eocene Tertiary fossils from Clairborne, 

 Alabama, amounting to sixty species represented by 806 specimens, 

 and a collection of Cretaceous fossils from Prairie Blifff, Alabama, of 

 eleven species, represented by forty-five examples, has been presented 

 by the Director. 



The additions to the arranged collection of Palaeontology in the 

 Museum building by the Director are given in an appendix under the 

 head of Current Work of the Museum. This list, with references to 

 plate and figure of those specimens used in description, shows a total 

 addition of 820 specimens among the Cephalopoda, of which 697 are 

 new to the Museum collections. The specimens of Camarocrinus 

 stellatus, described in the twenty-eighth Museum report and not before 

 arranged in the Museum collections, are also given in this appendix, 

 with reference to plate and figures. 



To the library, contributions have been made by societies and indi- 

 viduals of eighty-six books and pamphlets. 



The Current Work of the Museum. 



In the Botanical department, the accompanying report of the Bot- 

 anist, Mr. Charles H. Peck, will give an account of his work, with the 

 additions of one hundred and ninety-seven species of plants, of which 

 eighty-five are new to the Herbarium. 



The collection of insects, begun in 1879, has been continued with 

 considerable additions, but its progress was interrupted by the appoint- 

 ment of Mr. Lintner as State Entomologist on the 1st of July, 1880. 



Dr. D. W. Hartman, of West Chester, Pennsylvania, who has been 

 engaged in the special study of the shells of the genus Partula, kindly 

 offered to examine and revise the nomenclature of the species belong- 

 ing to the State Museum. The specimens were placed in his hands 

 and this work has been accomplished. Dr. Hartman has also contrib- 

 uted other species, which are noted in the lists of additions to tha 

 Museum collections. 



Mr. Geo. B. Simpson has prepared a collection of fresh -water shells, 

 to be placed in the Museum whenever cases can be provided. In addi- 

 tion to the usual exhibition of the species, a large number of trans- 

 verse and longitudinal sections of the specimens have been cut and so 

 arranged as to show the convexity of the valves, the comparative thick- 

 ness of the shell, and the capacity of the interior at different points in 

 the width and in different stages of growth. These sections have been 

 cut from specimens supposed to represent the opposite sexes of the spe- 

 cies, and furnish some very interesting material for study. This col- 

 lection will be accompanied by original drawings representing the ana- 

 tomical structure of the animal. 



The work of preparing sections of fossil corals and other families of 

 fossils, the cutting of larger specimens for the study of the interior, as 

 among the Cephalopoda, the shaping and polishing of specimens, and 

 the cutting of numerous sections of fresh-water and other shells, has been
