L. coronatus, Quatref. and Cl. intermedia, CErst., and add 
Sabella lumbricalis, Fab., it would seem desirable to accept 
this genus, which might be united with Nicomache, Malmgr., 
if we do not adhere to the number of twenty-two setigerous 
segments assumed by Malmgren in the generic character. 
Cl. intermedia must have fewer ; L. coronatus has only thirteen. 
Of Cl. ebiensis, which is perhaps identical with Cl. intermedia, 
and of Letocephalus parvus, Quatref., the posterior extremity 
is unknown: they cannot, therefore, any more than the above- 
mentioned Cl. spathulata, be numbered among the Ledocephalt. 
Near Clymene we should also have to place the genus 
Johnstonia, Quatref., some of the setigerous segments of 
which are furnished with richly sanguiferous ceca on the sur- 
face. In the only known species, J. clymenoides, Quatref., 
the last six setigerous segments are thus distinguished. 
b. In two species of Clymene only do we find the 
terminal funnel smooth-edged and destitute of teeth, 
namely, in Cl. urceolata, Leidy, and Ck letopygos, Gr. 
These might form a particular group (Leiochone); but 
they require that their examination should be repeated; it 
is a question especially whether the examined specimen of 
the latter has not a mutilated posterior extremity, as, con- 
trary to its condition elsewhere, uncini and sete exist even 
on the penultimate segment—and also whether the described 
anterior extremity, which is torn away behind, really belongs 
to this posterior extremity. In this case Cl. urceolata would 
be distinguished by the well-developed projecting margin of 
the vertical plate, which does not exist in Cl. lecopygos. 
2. The terminal segment does not form a funnel, and the 
anus is situated on the dorsal surface. 
In this section the genera Chrysothemis and Sabaco, Kinb., 
Maldane, Gr., and Petaloproctus, Quatref., should stand. In 
the first two the terminal segment, according to Kinberg, is 
not merely biannulate, but also divided into two parts in a lon- 
gitudinal direction by two lateral furrows, and is cut off short 
beneath and produced above; the sete are in part narrowly, 
and in part broadly margined, and in part furnished with 
denticulated margins; the uncini are stronger on segments 
2-4, but already form small combs, which are broader further 
on; they persist on the penultimate segment. I cannot detect 
essentially distinguishing generic characters between these two 
genera in the description. Hach of them is represented only 
by asingle species, and that an exotic one—C. amena, Kinb., 
and S. maculatus, Kinb. In Maldane and Petaloproctus the
