costate variety of F. pulcheUa present in Britain, and I recommend 

 tliat until it can be demonstrated more conclusively than has at 

 present been done that there are two British species, the costate form 

 be classed as a variety of the typical V, pulcheUa." The name 

 Tachea being preoccupied for a genus of birds, Cepcea Held is substi- 

 tuted. The nomenclature of ' Biiliminus " is discussed, and that 

 name is replaced by Ena of Leach, and the family name is changed 

 to Enidse. Pupa is discussed at length. It appears that that name 

 was first used for species of Actason and Oerion, and finally by 

 Drapernaud for what is now known as Pupa, Mr. Woodward con- 

 cludes that Jaminia Risso, 1826, is the earliest available name for 

 the Pupa muscorum group. 



In the Basommatophora, Phytia myosotis replaces the familiar 

 Alexia, preoccupied in Coleoptera, and Ovatella takes the place of 

 Leuconia, being earlier. Planorbis alaber J;ffr. is definitely sep- 

 arated from the American P. parvns. Mr. Woodward disputes the 

 propriety of Ball's course in substituting Corneocyclas for Pisiditim, 

 but otherwise the generic nomenclature of bivalves calls for no 

 special comment. 



Mr. Woodward uses the emended form&''Drei'ssensia," " Vivipara" 

 '' Aplecta" and '" Assemania," a course against the general usage

ON SOME MOLLUSCA KNOWN TO OCCUR IN INDIANA By W. S. 

 Blatchley and L. E. Daniels (27 Ann. Rep. Dept. Geology and Nat. 

 Resources of Indiana for 1902). This paper of 100 pp. is supple- 

 mental to the report on Indiana mollusks by Dr. R. E. Call, pub- 

 lished in 1899. Some 92 species are added to the fauna of the 

 State, a large number of them being figured and all described. Some 

 little known or new forms are among those illustrated, such as 

 Succinea calnmetensis Calkins, Limn/za woodruff, Baker, Ancylm 

 shimekii Pils.. Lithasia obovata biconica and Goniobasis indianensis 

 Pils., various Plsidia described recently by Sterki, Lampsilis 

 blatchleyi Daniels, etc., so that the report is of general interest to 

 those studying our inland mollusks. 



The same Annual Report includes A CHECK LIST OF INDIANA 

 MOLLUSCA WITH LOCALITIES, by L. E. Daniels. 277 species have 

 been ascertained to occur within the .State.
