* 7. Enchytraeus albidus, Henle. 
Three fine, adult specimens. Length averaging 12 mm., with 40 
segments. This and the foregoing, when found in ricli soil or manure 
will often reach the length of i inch (or 25 mm.), but size is only of 
relative value. Setae varying in different parts of the body as follows ; — 
Front. — Four dorsal and 5 ventral. 
Middle. — Two dorsal and 3 ventral. 
Posterior. — Usually 3 dorsal and ventral ; but occasionally 2 or 4 
Thus it frequently happens that the sets in the mid region contain the 
smallest number, whereas in many species the posterior end has the fewest 
Sperm-funnel 5-6 x i, narrow and long with clearly marked neck 
Duct large and stout, confined to segments 12-13, o'* i4- Very large 
pores on xii,, but no well-marked atrial gland within. 
8. Fridericia Michaelseni, Bretscher. 
Already reported for Poyntzpass. Setae 6 per set in front. Salivarics 
long and branched. Spermathecae with 2 diverticula and fairly long 
slender ducts. No glands at 4/5 opening. Rather stout and somewhat 
long ducts to the sperm-funnels in xii. 
+ 9. Henlea glandulosa, sp. n. 
Length 10-12 mm., segments 2,$- Setae 4-6 per bundle, those in the 
anterior part of the body similar to Fridericia, i.e., shortest in the middle. 
Three pairs of septals in the typical positions 4/5, 5/6, 6/7 ; thfe hindmost 
pair large. Girdle cells small. Very large glands at xii., with large 
pores ; funnel 2 x i, with large duct, irregularly coiled. Coelomic cor- 
puscles large and discoid. No oesophageal glands, intestine enlarged 
in 7, dorsal vessel arising in ftont of septum ■;/'&. Head small, as well as 
brain, which (as usual hi Henlea) is about i] x i, and slightly indented 
behind. Gizzard large. Dorsal vessel irregularly branched in segment 
4, and pulsing in 7, 6, 5. Spermathecae with glands, but no distinct 
ampulla. The anteseptal of the nephridia small, and the post-septal 
large. No salivaries seen. See figures on next page. 
In a Monograph of the Genus Henlea, now in the hands of the Sec, 
R.M.S., I have described something like a score of British species, but, 
so far as I can gather, not one of them agrees with this description, though
