EXPLANATION 



OF THE 



TERMS, SIGNS, AND METHODS OF RECORD 

 USED IN THE PRESENT WORK. 



! The exclamation mark is used in accordance with an accepted custom, 

 as a mark or token of verification, and indicates that the specimens 

 from the locality or district mentioned have been seen and verified by 

 the author. 



Records in which a date is given immediately after the name of the 

 locality signifies that the specimens were collected at that time. 



Records in which the date does not precede but follows the name of the 

 collector signifies only the date when the specimens were examined, 

 and that no precise record has been kept of the date when the speci- 

 mens were collected. 



The names of authors when placed within parentheses and following the 

 names of species implies that the generic name used is not the same 

 as that used by tlie original describer ; when the parentheses are not 

 used the species retains its original allocation. 



All Records and observations under each species are almost invariably 

 used only in association with the particular name used by the author 

 whose information is being made use of. This mode of treatment is 

 desirable, as though giving all information in its appropriate position, 

 it yet preserves the connection with the name to which it belongs, 

 so that if the reference to the particular species be objected to, the 

 information can be extracted, as it is not confused with other records.
