the two can not possibly be members of the same section. Therefore 

 the section Siyganodon must be accepted as valid and A. crispata 

 must be placed as the type of Anodontites s. s. At present it is 

 believed to be the only species thoroughly entitled to a place in that 

 section but showing relationship to others, which might well be 

 placed in a subsection, or perhaps better in a new section to include 

 sjDecies such as fubei^la Gould, tortilis Lea, luteola Lea, pittierl 

 Marshall, aroana H. B. Baker. These species have a type of perio- 

 stracum that has relationship to that of A. crisvata and to a lesser 

 extent to that of A. colomhiensis, but very little similarity to that of 

 A. tenebricosa. 



Simpson (1914, p. 1403) accepted the generic name Anodontites 

 instead of GIahar?s, which he had used in 1900. In 1914 his treat- 

 ment of the synonymy of A. crispata was as follows (rejecting such 

 references as were based upon simple citations of names unaccom- 

 panied by figures or descriptions) :

His treatment in 1900 was the same as the foregoing except that 

 Glabaris was used, and on page 919 there was a footnote to Anodonta 

 crispata Lamarck, saying : " Lamarck refers to Encyclopedie Metho- 

 dique pi. cciii, figs, 3, 3a, 3b," and a footnote to Anodonta pubei^la 

 Gould, saying: "According to Lea's note on the margin of this 

 description the species = cr/.s/>a^a. I think he is right." 



Lamarck's (1819, p. 86) description of Anodonta crispata was as 

 follows:

There is nothing in this description to show that Bruguiere and 

 not Lamarck was the author of cHspata except the reference to the 

 figures in the Encyclopedie Methodique. Those figures are a rather 

 poor reproduction of the figures published by Bruguiere with his 

 original description of crispata in 1792. A. crkpo) Lamarck is a mis-
