or also the number of the setigerous segments, in the esta- 
blishment of new genera. ‘To the author it appears to be 
advisable for the present to regard Malmgren’s genera as mere 
subsections. 
The genus Clymene would then include the following spe- 
cies :— 
With 16 setigerous segments: Cl. zostericola, Quatref. 
17 setigerous segments: Awiothea catenata, Malmgr. 
(which possesses 4 anteanal segments), C. modesta, 
(Juatref., and Cl. lyrocephala, Schm. 
18 setigerous segments, according to Quatrefages: Cl. 
uranthus, Sav. (Savigny ascribes to it 19 segments 
and 4 anteanal segments.) 
19 setigerous segments; with 5 anteanal segments: 
(Praxilla), P. pretermissa, Malmgr., P. arctica, 
Malmer., P. Kefersteinii, Kinb., Cl. gracilis, Sars, 
and Cl. Muellert, Sars ; 
with 3 anteanal segments: Cl. lumbricoides, M.-Edw. 
(Quatrefages indicates only 15-16), and Cl. dia- 
dema, Gy., 2. Sp. 3 
with 2 anteanal segments: Cl. digitata, Gr., and 
Cl. Girstedi, Clap. 
22 setigerous segments and 2 anteanal segments: Cl. 
palermitana, Gr. 
23 setigerous segments (?) and 3 anteanal segments: 
Cl. amphistoma, Sav.

Clymene diadema, Gr., discovered by Ritter von Frauenfeld 
‘in the Red Sea, like Cl. lwmbricoides, which occurs not un- 
‘commonly at St. Vaast, presents longer and shorter teeth on 
the funnel; but these alternate almost regularly, one of thelonger . 
ones standing between every two or three very short ones; 
the median strip passes through the vertical plate not, as in 
Cl. lumbricordes, as far as the middle, but nearly to the hinder 
margin, and does not project as a lobe at the frontal margin. 
Clymene digitata, Gen and Ol. Girstedi, Clap., are very 
similar; but the former, if the specimen examined was adult, 
is only one-third of the length of the other, its segments are 
much shorter and thicker to beyond the middle of the body, 
and the circular vertical plate has a distinct and entire margin; 
whilst in Cl. Grstedi this is rather rounded pentagonal, and 
not distinctly marked, and has an emargination on each side 
behind, 
From Clymene Quatrefages separates the genus Levocephalus, 
which, otherwise agreeing with it, is almost or entirely desti- 
tute of a vertical plate. If we omit this last character, retain
