tion with the parts to which they properly belong. That the 

 work was issued in nine parts or Heften is apparent from 

 the remarks of Kaltenbach in his Nachtragliche Bemerkungen 

 on page 329 (328 of later copies) of the work itself. 



Cams, in Bibliotheca Zoologica of 1861, gives the dates 

 1854-1857 for the whole work and assigns pages and plates to 

 each of the nine parts, as will be given in the following, but 

 does not give the year for the individual parts. Hagen gives 

 the dates for the parts in the Bibliotheca Entomologica as 

 follows: Parts 1-4, pp. 1-134; 24 plates, 1854. Parts 5-7, pp. 

 135-236; 18 plates, 1855. Parts 8 and 9, pp. 237-336; 12 

 plates, 1857. 



The number of copies distributed in parts was probably 

 small and on the completion of the work in 1857 the greater 

 part of the edition was united into one with a new title page 

 dated Niirnberg, 1857, in which condition most of the copies 

 now to be had are found. A copy in the Department Library 

 of Animal Biology of the University of Minnesota bears evi- 

 dence of one that was issued in the nine original parts though 

 later bound into one. The plates of this copy, as probably all 

 that were issued as separate parts, are much superior to any 

 of the later copies that I have examined. The copy bears the 

 title page, dated Niirnberg, 1857, which was probably issued 

 with the last part, but following this it also has the title page 

 of the Ersten Heft dated Niirnberg, 1854. The copy also 

 shows the torn off covers of the original parts between many 

 of them as given by Hagen. A second copy in my possession 

 has been separated into the nine parts as originally printed 

 based upon the evidence of the printer, the binder, and Cams' 

 and Hagen's data, which give further evidence of how the 

 work was published. It is a well known fact that bookmakers 

 will not print a sheet of less than 16 pages except at the end 

 of a work or for other good reasons. The presence of an in- 

 complete sheet at the end of each part, except one, therefore, 

 gives additional evidence that the part was completed before 

 the following was undertaken. All the facts as far as known
