Some distance before the ano-genital aperture is found a sup-

plementary organ, in shape recalling that known in certain En-

oploids, f. i. Enopliis {Enoplolainms) Butschlii Southern. The

distance between this organ and the anus makes 104 // in my

specimen. Besides this organ and caudad for it are found three

smaller supplementary organs quite like those known in the genus

Cyatholaimus and situated between the ano-genital aperture and

the above named supplementary organ (PI. VII, fig. 7). The distance

is almost alike between the three small organs; the distance between

the foremost two makes 21 //, between the hindmost two it makes

18 fi. The hindmost organ is situated 21 // from the ano-genital

aperture. The distance between the large supplementary organ and

the foremost of the small organs makes 60 //.

It has been impossible to refer the species in question to any

known genus. It shows relation to Cyatholaimus but the structure

of the buccal cavity is so different that il is impossible to include

it here.

Some specimens were taken of a form which I venture to

refer to Bastian's C. coecus. The size and other dimensions agree

rather well with the description of de Man; only the annulation

seems less coarse than it should be after de Man. The named ^

author indicates one row of points in every interannulary furrow .

and three on each ring. I have not succeeded in ascertaining

this in my specimens. The papillæ with chitinized base are, as in

C. coecus, arranged in double rows in certain parts of the body.

All my specimens being females I have moreover no support from

the spicular apparatus which in this genus seems to be of system-

atic importance.
