ZOOLOGY OF THE FAR EAST. 
prominent. The vent appears to be behind it and the genital orifices to the right of 
it. The eyes are distinct and set behind the rhinophores and a little to the outside 
of them. 
The internal anatomy seems to agree with what is recorded of other species of the 
genus Stiliger. The greater part of the body cavity is filled with the ramifications of 
the hermaphrodite gland. There are no jaws and the radula is of the ascoglossan 
type. The teeth are of the usual spoon- like shape and are not denticulate. There 
are 7 in the ascending portion of the radula, 11 in the descending and about 7, much 
broken, in the heap at the bottom. The radula is not spiral and not much bent. 
The pharynx runs into a pouch (presumably to be regarded as a stomach) , which lies 
across the body rather than lengthwise but gives rise to two longitudinal tubes which 
run along the sides of the body and communicate with the bases of the cerata by 
smaller tubes. 
This species differs from the other known Stiligers, and to the best of my belief 
from all other members of the family Hermaeidae, in having distinct pointed oral 
tentacles and tentacular prolongations of the foot. But it does not seem to me 
necessary to create a new genus for it on that account.
