Henlean type. Coelomic corpuscles not horny, of two kinds, the 

 larger granulated. No oesophageal glands or bulb ; the oesophagus 

 going gradually into the intestine. Strong gizzard extending from 

 segment 2 to 4. Eather long, narrow salivaries, with tips slightly 

 budding, or branching freely. First nephridia in 7/8 ; duct not 

 always issuing from the same part of the postseptal. In the 

 hindermost segments the duct tends to spring from the posterior 

 portion. 



Habitat.— Collected at Scarrington, Notts, June 10, 1913, by 

 Mr. H. Hillman, after whom it is named in recognition of the 

 splendid service he has rendered by his intelligent and indefatigable 

 collecting. 



4. Henlea insulse Friend. 



Collected in June 1913 by Mr. Hillman in Jersey, and first 

 described in Zoologist, December 1913, p. 460. 



5. Henlea inusitata Friend. 



First regarded as a variety of H. dicksoni, but found to be a 

 true species. Length variable (unless again two species are in- 

 cluded) ; 5-15 mm. Segments 25-45. Setae Fridericia-like ; 

 i.e. shortest in the middle of the bundle, three to six in posterior 

 bundles, five to eight in front, rarely in the most adult reaching 

 nine in a set. Brain typical, incised, concave or sometimes straight 

 or convex behind, according to tension. 



Nephridia begin in 5/6 or 6/7, duct as long as postseptal, 

 from the middle of which it usually springs. Sperinatheca usually 

 a simple duct, occasionally with glands at the 4/5 opening. Bulb in 

 segment 8, and dorsal vessel in 8/9. Salivary glands between the 

 second and third pair of septals. First described in Zoologist, 

 March 1913, p. 85. 



Habitat. — Frequently found, and formerly recorded as H. 

 dicksoni in part. Definite records for the new species are Eolleston 

 Junction, Notts, March 26, 1912 ; Cauldwell near Burton-on- 

 Trent, June 11, 1912, and again on April 7, 1913 ; Dundrum 

 Eoad, Dublin, March 7, 1913 ; Oxford Botanic Garden, April 15, 

 1913. 



6. Henlea minima Friend. 



Length 5-6 mm. Segments 25. Brain slightly concave behind, 

 converging forwards, of the usual Henlean type. Spermathecaa 

 like an Indian club or champagne bottle, without ampulla or
