162 R. H. MATHEWS. 
Under the group laws it is impossible for a Dilbi or Kupathin 
man to marry a woman bearing the same totem name as himself, 
for the reason that such a totem does not exist in the division 
from which he is bound to select his wife. But when persons of 
the same group were permitted to marry each other, it became 
necessary to promulgate a law prohibiting marriage between 
individuals belonging to the same totem. All such persons are 
supposed to have sprung from a common ancestor, and to be 
connected by ties of blood. Under no circumstances, for example, 
can a padamelon marry a padamelon because they are considered 
as brother and sister, or else as “ mother’s brother ” and “ sister's 
daughter,” according to their respective ages in the generation. 
If a Dilbi man wishes to marry a Dilbi woman, he must conform 
to the rules regulating the inter-marriage of certain totems within 
that group. For example, a man of a Murri padamelon family, 
can marry a ground iguana, but she must belong to his own 
section; that is, she must be a Matha. She cannot be a 
Kubbitha, because that is the section to which Murri’s mother 
belongs. The same course would be followed mutatis mutandis, 
in regard to the marriage of a Kubbi, an Ippai, or a Kumbo, with 
a woman within their own respective sections. 
These alliances may for convenience of reference be called 
“family marriages,” a few examples of which will be given. 
Among the Dilbi totems who can marry each other may be 
enumerated the following examples :—The padamelon marries the 
ground iguana, or jewfish. The opossum marries the ground 
iguana, bandicoot, or jewfish. The ground iguana marries the 
opossum, padamelon, bony fish, yellow-bellied fish, or bandicoot. 
The jewfish marries the opossum, padamelon, or bandicoot. The 
bandicoot marries the jewfish, opossum, or ground iguana. The 
bony fish marries the ground iguana. The yellow-bellied fish 
marries the ground iguana. 
The undermentioned Kupathin totems are amongst those who 
can intermarry. The emu marries the ring-tail opossum, black- 
snake, wallaroo, native bee, or galah. The bubbar snake marries
