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. 
Recorps in which a date is given immediately arrer 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 the original describer; when the parentheses are not 
used the species retains its original allocation. 
All Recorps 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,
