shorter. M fertile, with very long ciliated tract, at least in its 
lower two thirds forming often ramificated craspedonemes, without 
cnidoglandular tract but with a very short craspedion region; m 
fertile, in each quartette rather much shorter than Mi the half or 
a third of m with a not ramificated ciliated tract, terminating in a 
bunch of craspedonemes. The older m with a very small, the 
younger m with a somewhat more developed cnidoglandular tract, | 
all with a long craspedion region. B and b sterile, considerably 
shorter than m, with a short ciliated tract, terminating in a small j 
bunch of craspedonemes, and with a maeandric, well developed 
cnidoglandular tract. 
C o lo ur in formol: Column chocolate-brown, paler in the aboral ■ 
end. Marginal tentacles at the base chocolate-brown, the greater ! 
part of the tentacles pale brownish, on the inside in the middle j 
part of the base sometimes a longitudinal pale line, sometimes 
brownish lines are extending in the pale area. Labial tentacles 
pale brownish at the base, greenish in the upper part. Oral disc 
•dark chocolate-brown. Actinopharynx coloured as the distal part 
of the marginal tentacles (Mortensens specimen). Colour of 
spec. 2 in alcohol: Column grayish-brown. Marginal tentacles at 
the base brownish, paler in the middle region, grayish-brown 
in the apex. Labial tentacles uncoloured or somewhat brown¬ 
ish. Oral disc chocolate-brown with two broad, radial pale bands 
on both sides of the directive plan. Actinopharynx pale. 
Dimensions in contracted State (Mortensen s specimen). 
Length 7,5 cm, largest breadth 2,5 cm. Length of the inner marginal 
tentacles 2,5 cm, that of the outer 1,2 cm. Length of the labial 
tentacles 0,8 cm. Specimen 2 in expanded State: Length 11 cm, 
breadth about 1,8 cm. Specimen 3 in very expanded State: Length 
21 cm, breadth about 2 cm. 
Occurrence: Puerto Galera, Mindoro Isl. Sand. 1 specimen.

Institute of the University of Stockholm, 2 specimens. 
The arrangement of the mesenteries and the distribution of the . 
different parts of the filaments are in the three specimens irregular, 
especially in the region of the protomesenteries and in their vicin- 
ity. As the specimens were well preserved I am able to give dia- ■ 
grams of all three. Only the older mesenteries are designed. ^
