abstract. Forthwith naturalists took Sanger's name, unwittingly 
but unwarrantably fitted it out with new characters, and all the 
time thought they were strictly following the leader, or only legiti- 
mately supplementing his work. Fortunately nothing very much 
worse has resulted than some considerable confusion of nomen- 
clature, which has not however passed beyond the bounds of 
rectification, 
Sanger's paper has seemed in danger of permanent consignment 
to oblivion; all the more so, perhaps, under the delusion that of 
late years observers had supplemented what little was known of 
it with all that was necessary for the exact identification of the 
species. It happily occurred to Prof. Spencer when on a visit to 
England recently, that the satisfaction of knowing exactly what 
Sanger had said on the subject might possibly prove to he 
sufficient compensation for the expenditure of the trouble necessary 
to get at it. He therefore took the matter earnestly in hand, and 
with the co-operation of Prof. Howes, Mr. H. M. Bernard, and a 
friend of the latter's, he at length became possessed of a trans- 
lation of that part of Sanger's paper descriptive of the Australian 
Peripatus. I have to thank Prof. Spencer not only for a copy of 
the translation, but also for his permission to make use of it. 
Before considering the translation, one or two other matters may 
be noticed. 
Some years before the re-discovery of Peripatus in Australia, 
the New Zealand species came to light. During the stay of 
H.M.S. "Challenger" at Wellington in July, 1874, Mr. Travers 
brought specimens to Mr. Moseley, who says that he was unable to 
refer to special publications at the time, and he thought that it 
was " already certainly named;" afterwards on his return to 
England press of work prevented his giving further attention to 
the matter. Very shortly after it came under Grube's notice, 
who refers to it in a paper read in 1875. I am unable to consult 
this paper * which is thus noticed by Leuckart : " Grube
