maturity, owing to the death of the mother. This happened in June, 
and judging from the state of their development, they would not, 1 
think, have been born for some weeks. They were quite white, but in 
“every way perfectly formed, including the “ tentacles.” The genital 
organs of all the males were extruded, rendering the differentiation of 
sex an easy matter. In the process of examination, some of them were 
allowed to become dry so that a count at that point could not be made. 
Length of the mother, 770 mm. 
The costals are counted two heads’ lengths behind the head, 
at mid-body and two heads’ lengths before the vent.

From the above list it will be seen that the number of scales in 
this species is by no means regular, and in this particular it resembles 
the true sea-snakes. The ventral shields also are extremely small, 
being not more than twice the breadth of the adjacent costals. They 
are sometimes missing entirely, and anteriorly are indistinguishable 
from the costals, making a true count difficult.
