84 THE ZOOLOGIST. 



from 6 to 9 in the ventral ; shortest in the middle, as in 

 Fridericia. Three pairs of septal glands normally disposed, the 

 hindmost pair being different from the others. Between the 

 second and third pair nephridia-like glands occur. They differ 

 from those of H. alba described above, but apparently belong to 

 the same class, though at present it is impossible to decide 

 whether they are oesophageal or salivary glands. Their unusual 

 character explains the specific name. Bulb in segment 8, and 

 dorsal vessel in the intersegment 8-9. Girdle covering segment 

 12 to setae of 13 with gland-cells recalling those of Fridericia 

 bulbosa, Eosa. Brain slightly longer than broad, somewhat 

 wider behind than in front ; slightly concave when stretched ; 

 but straight or convex behind when at rest. Ccelomic corpuscles 

 granulated, not horny or brown. Sperm funnel very small ; no 

 conspicuous atrial glands, penis or male pores. Spermathecae 

 consisting of a simple duct without distinct ampulla, bulb, or 

 glands. Large blunt anteseptal, the whole nephridium re- 

 sembling a leg of mutton. 



Collected at Rolleston Junction, Notts, March 26th, 1912, in 

 a heap of earth. Also found at Cauldwell, near Burton-on-Trent, 

 June 11th, 1912. 



3. Henlea minima, sp. nov. 



Length 5-G mm. Segments 25. Setae 4-5 posteriorly, as 

 many as six in front, growing smaller towards the centre of the 

 bundle, as in Fridericia. But the Henleas vary in this matter 

 a great deal. Three pairs of septals in normal position, small 

 in front, medium, and large behind. No oesophageal glands ; 

 no salivaries ; no nephridia-like glands between the septals. 

 Brain similar to that of H. inusitata. Spermathecse in the form 

 of a tube, widest near the opening and narrowing towards the 

 intestine. No ampulla, bulb or glands. Girdle extending as 

 usual from segment 12 to setae of 13. Ccelomic corpuscles large 

 and clear, not horny; somewhat oval in shape. Intestine widens 

 in segment 8, dorsal vessel arises in 10-11. Small anteseptal 

 and large postseptal with duct as long as the latter, from whose 

 mid-region it arises. Very fine sperm-duct opening into an 

 atrial-gland in segment 12. 



Collected with H. alba at Netherhall, between Bretby and 

 Hartshorne, where I have taken Rhyacodrilus and other rare
