of the body, a photograph is not reproduced. Instead I give a camera 
drawing of the animal cut in halves (text-fig 5). There are only 
the slightest traces of two tentacles, in the 
shape of hardiy visible protuberances of a 
circumference much smaller than the group 
of tentacular eyes. 
The colour of the alcoholic specimen is 
i on the upper surface a uniform dark greyish 
^ green. No trace of a pattern is visible, nor 
does the series of sections show any accumul- 
ations of pigment granules in the body tissues. 
, The colour seems to belong to the epidermis. 
Measurements: The animal measures 
roughly 15 mm in length, and the greatest 
breadth (just where the mouth lies) is 6 mm. 
The brain, of a broad, rounded shape, lies 
about 2 mm behind the frontal margin, thus 
j being somewhat nearer this than the pha- 
ryngeal pocket. The mouth is subcentral. The 
pharynx is about 5 mm long; that is, a third 
of the body-length, and its distance to the 
anterior margin slightly surpasses that to the 
posterior body-end. The sexual openings lie 
. close to one another, their interdistance being 
only about O.is mm. The female pore is 
j situated O.s mm from the caudal end of the 
'body; that is, about Vi9 of the body length. 
In the location of the sexual openings we thus 
meet with a close resemblance to the general 
conditions in the genus Stylochus. Arrange¬ 
ment of eyes: There are marginal eyes all around the body. 
Their distribution in one or two rows at the anterior body-end is 
shown in text-figure 6. In the posterior two-thirds, the ocelli are 
far more scattered (text-fig. 8). For a member of ihe family 
Stylochidae the cerebral eyes (text-fig. 6) show a rather small 
number. They are arranged in two clusters. The tentacular eyes, 
jless than 10 in each group, are more scattered than could be expected 
from the extension of the insignificant tentacular protuberance. 
cut in halves. As the 
figures are drawn with 
the help of Abbes camera 
and the body halves are 
slightly hent ventral- 
wards in the sagittal line 
and dorsalwards in the 
transverse line, a certain 
allowance for these cir- 
cumstances must be 
made. The anterior part

part in ventral aspect.
