CONTRIBUTIONS TO THE TERTIARY Fauna or Fiorina. TRANs- 
ACTIONS OF THE WAGNER FREeE INSTITUTE, OF ScIENCE.— Vol. 
III, part 3. By Wm. H. Dall, A.M. This forms an introductory 
chapter to Prof. Dall’s work on the Tertiary Pelecypoda of Florida, 
and contains a new classification of the Pelecypoda, with an enum- 
eration of the differential characters of the Orders, Suborders, Super- 
families and Families, a statement of their range in geological time, 
and au enumeration under each family of the chief generic groups 
believed to be referable to it. The paper is prefaced by a brief dis- 
cussion of the features of the Peleeypod organization chiefly avail- 
able as diagnostic characters. Continued study of this group has 
confirmed the author in the opinion that in its general features the 
classification which he proposed in 1889 (founded largely on the 
characters of the hinge, see Amer. Jour. Sei., X XX VIII, 445), and 
has now revised, comes nearer to meeting the requirements of the case 
than any other which has fallen under his notice. In describing 
the ligamental characters the term “resilium” is proposed for the 
so-called “cartilage” or “internal ligament.” The Steinmann 
Formula, based on the teeth, sockets and resilium, is thoroughly ex- 
plained. The Pelecypoda are divided into three orders — Prionodes- 
macea, Anomalodesmacea and Teleodesmacea. ‘he first order con- 
tains thirty-four families, leading factors being Solemyide, Nucu- 
lide, Arcide, Ptertide, Ostreidw, Unionide, Trigonide, Pectenida, 
Anomiide and Mytilide. Each of the above and of the following 
families being the typical representatives of a Superfamily. The 
second Order contains fifteen families, typical ones being Anatinide, 
Clavagellide, Poromyide. ‘The third contains forty-seven families, 
such as Pleurophoride ?, Astartide, Cyrenide, Carditide, Chamide, 
Hippuritide, Lucinide, Leptonide, Cardiide, Tridacnide, Isocar- 
diide, Veneride, Tellinide, Solenide, Mactride, Myacide and 
Pholadide. The paper is concluded with some timely notes on 
nomenclature.— CO. W. J.
