The general colour of the alcoholic specimen was slightly brownish 
on the dorsal side, without being noticeably more concentrated 
along the median line. There was no pattern of any kind retained. 
No notes were taken as to the colour during life. 
The tentacles are so inconspicuous that only the tentacular group 
of eyes situated thereunder proves that the slight prominences in 
question really represent rudimentary tentacles. They are located 
at the posterior border of the first fifth of the body, and have a cir- 
cular outline; their diameter is comparatively large. A line connect- 
ing them would run a short distance in front of the brain. 
The brain is inconsiderably longer than it is wide, with straight 
posterior and slightly indented anterior horders. 
The mouth is situated at the end of the second third of the 
body, and that would be at the border between the second and 
last thirds of the pharyngeal pocket. The pharynx is relatively 
short, only about a third of the whole length of the animal. As 
the greater part of the pharynx lies back of the animal’s median¬ 
point, the distance from the pharynx to the posterior margin of the 
body is about Vs the distance from the pharynx to the frontal line 
of the body. For being that of a Stylochid, the pharynx is mode¬ 
rately folded and the pharyngeal pocket has only a few, but very 
deep side-chambers. The alimentary system otherwise presents 
ordinary features, and it might only be mentioned that the simply 
branching coeca are not very densely arranged (Plate II, Fig. 1). 
The genital pores lie very close to each other, separated only 
by an interstice, Vio mm wide. They are located at about half 
the distance between external mouth and the posterior margin of 
the body, the female aperture being roughly 2,2 mm from the 
caudal end of the animal. 
Arrangement of the eyes: The marginal eyes are nu- 
merous but very small. They occur chiefly at the anterior third 
of the body. Proceeding backwards, their number soon diminishes, 
and in the pharyngeal region there are only a few scattered ocelli. 
In spite of a diligent search, I have not been able to prove the 
presence of any eyes at the extreme posterior end of the body. 
At the frontal margin the more peripheral eyes arrange themselves 
in several rows as a narrow band, but interior to this they are irre- 
gularly and sparsely distributed in somewhat separated clusters, as is
