Lea's original description. — Shell scaleniform, very compressed, 

 transverse, very inequilateral, smooth and shining, furnished with two 

 lamellar lateral teeth ; substance of the shell very thin ; beaks very small 

 and pointed ; cavity of the shell extremely shallow ; margin entire. 



Diam. nearly .1, I,ength .2, Breadth 7-2oths, of an inch. 



Observations. — Differs from the ovalis, which it most resembles, in 

 being smooth, more compressed and more angular. 



In No. I of this series of Bulletins ('95) I called attention 

 to the fact that Idea's "Fig 24" and "Fig. 25" had been inter- 

 changed. Dall has followed this correction, but has failed to 

 note that Gregorio used the species still changed about, as it 

 were. ''Donax plana'' of Gregorio is therefore a synon5'm of T. 

 leana Dall {ovalis Lea), and not T. plana as Dall states (op. cit. 

 p. 1016). 



Cossmann regards ovalis and pla?ia as synonyms. See 

 footnote p. 9, Notes Complement. &c, 1893.
