In attempting to classify this worm, we find no characteristics 
which would exclude it from the family of the Maldanidae (Maldaniae 
Savigny, ’20) as emended by Grube (’G8), except the number of 
segments, which Grube makes never greater than twenty-seven. In 
all other respects the wo'rm would belong in this family. It contains, 
however, probably more than seventy segments. 
Malmgren (’05) in establishing the genera of the family lays 
great stress upon the number of segments, both the total number 
and the number of setigerous segments, and he breaks up the genus 
Clymene of Savigny into several genera depending upon these char¬ 
acters. If we should follow Malmgren, it would be necessary to 
establish for this worm a new genus. 
De Saint Joseph (’94) in his recent extensive work goes over the 
whole ground of the classification of Maldanidae and, disregarding 
entirely the number of segments, — the total number in the body as 
well as the number of the preanal segments, — bases his distinction 
of genera upon the following characteristics : — 
1. Form of head. 2. Form of anal segment. 3. Form of ventral 
uncini. 4. Presence of acicular setae replacing the uncini in a 
certain number of anterior setigerous segments. 5. Absence of 
either acicular or hooked setae from a certain number of anterior 
setigerous segments. 
Saint Joseph regards this, the fifth point, as an invariable charac¬ 
teristic of all species. By this revision he reduces the whole number 
of genera in the family Maldanidae to twelve. 
Accepting Saint Joseph’s basis of classification, which seems to 
me the most accurate and reliable one yet published, there is 
nothing to exclude this worm from the genus Clymene Savigny as 
defined by Saint Joseph. On account of the length of the worm, 
which is greater than that of any other member of the genus which 
I have found described, I propose for it the name Clymeneproclucta. 
In view of Saint Joseph’s classification, there seems to be no reason 
whatever for retaining the genus Clymenella established by Verrill 
(’73). For Verrill has given no truly generic characters which 
would separate Clymenella from the genus Axiothea of Malmgren 
(’G5) . Saint Joseph therefore places Clymenella torquata Verrill in 
the genus Axiothea Mgn., basing his conclusion upon the fourth of 
the generic characteristics given above—ventral setae with hooks 
being found in the anterior setigerous segments, as well as in all 
the other setigerous segments.
