The dorsal vessel arises in the ninth segment, and the vessel 
pulses forwards to the sixth. Nosalivary glands or oesophageal 
glands present. The brain is concave before and convex 
behind, hardly twice as long as broad. The sperm funnel or 
ampulla is about of the same relative proportions, and the duct 
is very small but long. The head is sometimes slightly glandu- 
lar, and the girdle extends from the beginning of the twelfth to 
the sete of the thirteenth segment. There are no sete on the 
twelfth segment in the adult worm. There are three pairs of 
septal glands in 4/5-6/7, and the coelomic corpuscles are large, 
oval, or discoid. The front commissures of the dorsal vessel 
join the bifurcated ventral vessel just behind the first set of 
sete. We need much more detailed observations on this point 
than have hitherto been made, as the vessels in the anterior 
regions shew widely different arrangements, and these will have 
to be included in future systematic descriptions. 
This species is closely related to Henlea tenella Eisen, in 
which, however, the brain is about as long as broad, the anterior 
and posterior being notched. 
6. Henlea lampas Eisen? In 1878 Eisen described several 
new species of Archienchytreus from Siberia and elsewhere. 
They are placed with diffidence by Michaelsen under the genus 
Henlea. So long ago as 1898 I found some specimens of an 
Enchytreid at St. Anne’s-on-Sea, Lancashire, which agree with 
Eisen’s description of Archienchytreus lampas very closely. 
In those days descriptions were not so perfect as now, but I 
record this species because I believe it belongs here; and if 
further research should show that it is wrongly placed, we shall 
have an authentic early record for some other British species. 
When we remember how recently the study of this large group 
of worms has been taken up systematically in this country, 
and that the number of Henleas at present known to science 
does not exceed a dozen, the list here supplied is certainly not 
an unsatisfactory one. Will readers help to make it more 
complete by sending specimens to 110 Wilmot Road, Swadlin- 
cote, from various localities, at home or abroad.

We have received Vol. II., No. 3 of The Journal of the East Africa and 
Uganda Natural History Society. Longmans Green & Co. 78 pp., 5/4. 
It contains a valuable series of papers on the Birds in Uganda Forests, 
Distribution of Game, Anthropometry, Geological notes, and other items 
of interest to naturalists. There are a number of illustrations of Uganda 
game, etc., one of a Cape Buffalo (the record head), being. particularly 
interesting.
