number, form, and arrangement, according to the species, 
resembling in turns those of *videricia, Buchholzia, Pachydrilus, 
and Enchytraeus. In some species there are oesophageal 
glands at the commencement of the intestine, in others they 
are wanting. These must be clearly distinguished from the 
septal glands which are always present. 
1. Henlea nasuta Eisen. The synonomy is fully given in 
‘Das Tierreich,’ x. 69. It appears as H. leptodera Vej. in 
Beddard and elsewhere. First British record, Friend in ‘ The 
Naturalist,’ 1896, p. 298. I first made the acquaintance of 
this species in May, 1892, when I found it between Idle and 
Woodhouse Grove, Yorkshire. During the same year I received 
it from Mr. Allen, a Plaistow correspondent, who collected it 
in Essex. In 1896 it was again discovered by me near the 
Goods Station at Cockermouth, and more recently I have 
obtained it from other localities. In 1909, Southern recorded 
it for Ireland. It is about 20 mm. long and 1-2 mm. broad, 
the number of segments varying from about 50 to 65, while the 
sete may sink in number to 2 and rise to 7, the average number 
being 4-6. The dorsal vessel arises in the 8th segment, in front 
of which the oesophagus enters the intestine. There are two 
oesophageal glands, and the brain is a little longer than broad, 
with a concavity in front. This species has been found in 
Siberia, Denmark, Germany, France, and Italy, and is readily 
recognized by its two oesophageal glands. 
2. Henlea ventriculosa D’Udekem. Found in May, 1892 at 
Idle, near Bradford, Yorks. Received the same month from 
Essex, through Mr. Allen of Plaistow. In 1896 found at 
Cockermouth under moss by trickling water. (Friend in 
“ Essex Naturalist,’ 1896, Vol. [X., p. 110). Found by Southern 
in various parts of Ireland. (‘Irish Naturalist,’ 1907, Vol. 
XVI., p. 70). It is 15 to 20 mm. in length, and averages 60 
segments. There are four oesophageal glands. The salivary 
glands are usually rudimentary or inconspicuous, whereas in 
the last named species they are well-developed. 
3. Henlea puteana Vejdovsky was first described in 1877 
as an Euchytreeus, but was transferred to this genus in 1889 by 
Michaelsen. It is at once distinguished, as Beddard remarks, 
by the presence of two pairs of spermathece. This is a unique 
characteristic ; no other Enchytreid having yet been found 
which possesses the peculiarity. They are in segments IV. and 
V. The dorsal vessel arises in segment IX. I found the species 
in Ledbury Churchyard, on Easter Monday, April 17th last. 
Unfortunately, owing to my absence from home, I was unable 
to examine the material in detail, and the putrid state of the 
decaying vegetable matter soon caused the worms to die. 
Henlea dicksont Eisen, of which two specimens have been 
found by Southern in Lambay, and Henlea hibernica Southern 
are as yet unknown in England.
