From this table it will be seen that a separate anterior cutaneous 
nerve may be associated with a moderately developed lateral cutaneous 
nerve and with any form of distribution of the lumbo-inguinal nerve. 
There is no indication that sex or race has influence on the frequency 
of development of this nerve. It was found more frequently on the 
left side than on the right, but this might not hold true were a greater 
number of instances studied. In only one instance was the nerve found 
on both sides of the same body. The following table indicates the race, 
sex and side of body in which the fourteen instances here studied were 
found.

The separate anterior cutaneous nerve is distributed on the thigh in 
company with branches derived directly from the femoral nerve. As a 
rule it is distributed in a territory separating that of the lateral cuta-
