that of Pompholyx, bnt was so injured by thè pi’ocess that its

The rhachidian tooth, in this specimen, was apparently mal- 
formed thronghont thè entire length of tlie ribbon. It was one- 
sided and nnsymrnetrical — not an uncommon malformation 
aiiiong pnlmonates. A few more normal tlian thè rest ap- 
peared to resemble thè same tóoth in P ompholyx^ bnt possessed 
only one denticle instead of two. The entire odontophore re- 
sembled that of Pomjyholyx, except in its greater breadth and 
more numerons uncini ; and in thè greater lateral prolongation 
of thè bases of thè teeth; Avhile thè cnsps were somewhat 
smaller in proportion to thè bases than in that genus. 
The first lateral is broad trilobed and resembles thè same 
tooth in Pompholyx, except in thè wider base and siightly 
shorter cusp. 
The same may he said of thè next nine laterals. The 
eleventh and siicceeding laterals, which, for distinetion, I will 
cali uncini, exhibit some diflerence of forni. Their bases are 
mudi prolonged laterally, thè shafts are slender, and thè short 
rounded cusps carry from three to five denticles. These ex- 
hibit some irregularity, as is usuai in tliis part of thè ribbon. 
The extreme outer uncini have shorter shafts and bases, and thè 
cusps are'almost, if not quite simple. The line in which thè 
teeth are set is more curved than in Pompholyx. The formula 
is 36.1.36, and there are about onehundred and fifty rows. The
