are less distinct, and there is no median longitudinal furrow internally on each side. A 
ridge occurs at each pole, and the clear globules exist in the hypoderm, which has a 
tolerably even disposition all round. The organ is less rounded in section than the 
preceding. 
Family Acoetida:. 
The family of the Acoetidse was established by Kinberg^ (his Family IV. Acoetea) for 
the two genera Eupompe and Pantlialis. Only a single example occurs [in the present 
collection, but it adds something to our knowledge of the group, since in addition to the 
pedunculated eyes (ommatophores) it presents a j^air of sessile eyes behind them. 
Kinberg’s reference to these organs, viz., “ Oculi pedunculati duo ; sessiles nullas vidimus,” 
will no longer apply. Three species were procured by Kinberg, but none by Schmarda. 
A single example is mentioned in the collection made by the German ship “ Gazelle,” and 
another in Grube’s Philippine Annelids. The representatives of the family seem to be 
comparatively rare in all parts of the world. Only one form occurs in Britain, viz., the 
northern Pantlialis oerstedi, Kinberg. 
Eupompe, Kinberg. 
Eupompe australiensis, n. sp. (PI. XXL figs. 4, 5 ; PL XXIII. fig. 8 ; PI. XXIV. 
fig. 4 ; PL XXIIa. figs. 2-6). 
Habitat. — A fragment of the anterior region was procured at Station 186 (apparently 
off Cape York, Australia, and probably in Endeavour Strait), September 8, 1874; 
lat. 10“ 30' S., long. 142° 18' E. ; depth, 8 fathoms; surface temperature, 77°’2 ; sea- 
bottom composed of coral sand. 
A large form, the fragmentary anterior region measuring about 50 mm. in length, the 
diameter at its widest part being 24 mm. It is tinted on the highly convex dorsum a 
fine bluish-purple, probably arranged in transverse bars in life ; and a pale band occurs 
in the preparation at each segment-junction. The entire segment is closely and 
distinctly marked with transverse furrows. 
The head (PL XXL fig. 4) is characterised by the two large ommatophores, the tips 
of which would seem to project outward beyond the margin of the scales in life. The 
greater part of these organs is deeply coloured with blackish pigment. Unfortunately the 
tips are considerably injured. They are iridescent, but show no special corneal differen- 
tiation. The ommatophores are together wider than the head. A little behind the base 
of each peduncle, and rather to the outer side, is a small sessile eye ; and between these
