families ending in id(S, — so that the references are evidently 

 incorrect. Dumeril and Bibron use Ellipsiglossus as a genus, 

 and Merrem uses Molge as the name of the genus which Lau- 

 renti had called Ti'iton, and which contains all the Urodele 

 Batrachians. 



On examining the nine subfamilies characterized by Dr. Hal- 

 lowell, I find them to be just nine of the tribes or sections of 

 tribes into which I had separated the three families into which 

 I had divided the Order in my Catalogue of these animals pub- 

 lished in 1850, — a catalogue well known to Dr. Hallowell, as he 

 quotes it among the synonyma of the species, and criticises some 

 of the observations in it in his remarks appended to the species. 

 Dr. Hallowell's subfamilies are established on the same characters 

 that I used to separate the families and tribes, the characters 

 being only given in a few more words, as if to fit them for a 

 work in quarto. I will now give an abstract, in parallel columns, 

 of Dr. HallowelFs and my arrangement : —

§ In a paper read at the Zoological Society on the 9th of March, 1858, 

 I divided this family into three, viz. Salamandridce, Pleurodelida:, and 

 SerianotidcB, but on very diflferent characters from those used by Dr. Hal- 

 lowell, and containing different genera to the families he has so named.
