I have little to add to the excellent description of Vejdovsky. 

 As many as three spermatophores figured by me, some 15 years 

 ago, in specimens taken at Tipton. Eeported to Irish Naturalist,

Lininodrilus udekemianus var. ivordsworthianus Friend. — 

 Length 50-70 mm., slender, slightly stouter at segments 6-14 

 than elsewhere. Segments from 90 upwards. Head pointed. Setse 

 4-5 rarely 6 in front, with large upper tooth ; present on girdle 

 segment ; three in middle of body, then in pairs to the end. Brain 

 with two large processes in front, slightly concave behind. The 

 pharynx in segments 2-3 ; head and peristomium papillose. Chlora- 

 gogen cells begin in 5, dilated hearts in 8 and 9. Penis-sheath

1898. — Zoologist, 4th ser. ii. p. 120. This worm was found in 

 a disused quarry at Old Carlisle at the roots of water plants, along 

 with typical Udekemianus ; and notes of the two, with drawings, 

 were made at the time from living worms. Notice the pharynx, 

 number of setae, shape of brain, and duct of spermatheca. On 

 April 28, 1899, I found corresponding forms at Sutton Coldfield. 

 It may be well for the present to regard it as a variety, but my 

 own opinion is that we have here a good species. It differs widely 

 from Claparede's type, as shown by his drawings, Mem. Sc. Phys. 

 Geneva (1862) p. 243.

3. Limnodrilus claparedeiamis Eatz. 



A red worm with somewhat long prostomium. The setae in 

 front from 5-8 per bundle, -with upper tooth longest. Brain with 

 a deep excision behind of a squarish form. The pharynx extending 

 back to the fifth segment. Penis-sheath 8-10 X 1, straight or 

 slightly curved with funnel-shaped widening. Length 50-80 mm.
