on each label to avoid the danger of mistakes occur- 

 ring in case exchanges are made with collectors 

 using a similar system. Each of our students using 

 this system has his name printed 

 Coraeu u. Cornell u. Cornell u. jn the correspooding place on 

 his labels. The blank space 

 after the abbreviation Sub. is 

 used only when it is necessary 

 to give a subnumber, as indi- 

 cated above. A narrow blank 

 space is left below the place 

 for the subnumber in which a 

 date may be written. 



Numbered Lots of Specimens. — The method of labeling 

 specimens described above will be sufficient for the needs of those 

 whose collections are small. The following suggestion is for those 

 having charge of large and rapidly growing collections: — 



It often happens that a large number of specimens, not all of the 

 same species, are to be labeled, respecting each of which precisely 

 the same record is to be made. It is my practice to give each lot 

 of specimens of this kind a number, and to place on each specimen 

 a label indicating the lot to which it belongs. In a note-book, kept 

 especially for this purpose, and known 

 as the Lot Book, a full account of each 

 lot is written. By doing this the record 

 is as complete as it would be were each 

 specimen given a number, and a note 

 written for each. Fig. 285 represents 

 a sheet of the labels used for this pur- 

 pose. The following extracts from the 

 Lot Book of Cornell University will illus- 

 trate the application of this system : — 

 Lot 30. — Lepidoptera from Colorado. 



These were collected and presented to the university by Mr. 



H. W. Nash. See Letter File I, page^43. 

 Lot 31. — Coleoptera from Arizona. These were collected by Mr.
