The lateral organ is circular and situated at the level of the

buccal cavity (PI. X, fig. 5). Some distance more caudad is seen

an eye consisting of a cup-shaped heap of black pigment granules;

presumably this cup has contained a refringing lens, but this is

not seen in the specimen. Behind the pigment cup is seen another

less prominent heap of pigment granules.

The æsophagus is of uniform width during its whole length

there is no bulb. Ventral gland not seen.

Female organs symmetricai. The female pore is situated some-

what in front of the middle and appeats to be an almost circular

aperture (PI. X, fig. 8). The ovaries are relatively short and re-

flexed. In the uterus only one shell-egg is seen. Cephalad and

also caudad for the egg is seen a heap of densely crowded sperm-

atozoa presumably included in the receptacles which are not distinct.

As it will be rather easy to recognize the species if met with

later on I have included it in my descriptions. I have — when

even with some hesitation — referred it to the genus Chroma-

dora. It is possible that it ultimately will prove necessary to

establish a new genus for this form.
