THE AMERICAN NATURALIST [Vol. XLV 



He discusses again the relationship of Li/sornphus and in his 

 discussion quotes the reviewer as saying what he did not say. 

 The point of the reviewer's criticism of the reference of Lijsoro- 

 phus to the Frodela was not the presence of ribs nor yet the 

 snake-like character which Dr. Broom explains in a very elemen- 

 tary way, but it was the character of the ribs. Their long, curved 

 condition is unknown among other Caudata and the reviewer 

 does not feel satisfied that LijsoropJius is a Vrodele even though 

 limlis should he discovered. 



Dr. Broom suggests for the newly described Oymnarthrus of 

 Case an amphibian relationship. The dorsum of the skull shows 

 characters, however, which a ppa retitly ally it with Pariofirh us. 



Dr. Broom's other essay (11) on practically the same subject 

 matter gives the additional suggestion that the American and 

 African amphibia are "two different modifications of the same 

 earlier fauna.' 



Mr. Robert Dunlop (12) has given some interesting notes on 

 Carboniferous and other Paleozoic amphibia of Scotland con- 

 tained in the Kilmarnock Museum before they were destroyed 

 by fire. His notes are accompanied and illustrated by two excel- 

 lent half-tone plates of photographs of type specimens of 

 Loxomma, PtcropJa.r and Anlhracosaurus. all of which is very 

 welcome information. 



Jaekel (14) has proposed a new classification for the Chordata 



subgroups Tctrapoda. Pisces and Tunicata. and makes no allow- 

 ance for amphioxus. He proposes two new classes of "Tetra- 

 poda," Hemispondyla and Microsauria with the ordinary classes 

 Amphibia. Keptilia. Aves and Mammalia. The forms he groups 



group which he ealls S.-l.-n.c.-pholi. Dr. Jaekel has made several 

 bad blunders in this' classification. The first one is to separate 

 the braiiehiosaurs from the Amphibia, to which they belong with- 

 out the slightest shadow of a doubt. The next one is the alliance
