application of the rules of nomenclature. The following extract 

 from Dall's Report to the American Association for the Advance- 

 ment of Science (1877 Meeting) "On Nomenclature in Zoology 

 and Botany" (p. 45, § Ixii.) makes a fitting conclusion to a dis- 

 cussion on this synonymy : — 



"The following kinds of works are entitled to citation in 



bibliography, but not in synonymy: — 1 2 3. Works 



not published. 



" It may seem superfluous to object to works of the third 

 category. But besides several MSS. preserved in museum libraries 

 and sometimes quoted, though never printed, there are a few 

 works that have been printed but never published. This is the 

 case with a Museum Catalogue prepared by Link about 1806. 



" It was printed and contained a host of new names. But 

 whether the author was ashamed of his work, or the authorities 

 of the University declined to be sponsors for the innovations, the 

 work was never offered for sale, distributed, or advertised by the 

 author. 



"Only one copy is definitely known to have escaped from the 

 University cellars, and it has been stated that the remainder, or 

 most of them, were destroyed by fire. Yet in 1851, the solitary 

 copy having been discovered, one or two authors called attention 

 to it, and demanded that these names should take precedence of 

 those of Lamarck and others, which had been in use for nearly 

 half a century. A few writers have adopted this suggestion, and 

 in one branch of science at least, deplorable confusion has resulted. 



" The auctioneer's catalogue of Bolten's collection printed in 

 1798, but fortunately containing no diagnoses, and of which only 

 one or two copies are known, falls nearly in the same category. A 

 reprint was made in 1819, but is also one of the rarest books." 



The Family Name. 



The consideration of what name should be applied to the 

 family has been complicated by the action of Dall and Simpson. 

 They have, without giving any reason, divided the group known 

 of old as Triton into four genera, and, while admitting Lotoriiim^
