DISTRIBUTION OF BRITISH ANNELIDS. 69 



tetrcedrus, (5) A. long a, (6) A. turgida, (7) Eisenia rosea, (8) O. 

 lacteum, (9) L. rubellus, (10) E. foetida, (11) Dendrobcena arbor ea, 

 (12) Bimdstus eiseni, (13) Z>. subrubicunda, (14) L. rubescens 

 (=festivus), and (15) 0. gracile. Total, 15. 



29. Northants. — My study of the annelids of this county 

 dates from 1891. During that year I received from Mr. Henry 

 Blaby, of Brackley, sundry consignments containing eight well- 

 defined species. Concerning these and some others an account 

 appeared the following year in two articles contributed to the 

 ' Field Club.' My original records stand thus : — (1) L. rubellus, 



(2) A. turgida, (3) A. chlorotica, (4) A. longa, (5) L. terrestris, 

 (6) L. castaneus, (7) D. subrubicunda, (8) Eisenia rosea (= A. mu- 

 cosa). In February of the following year (1892) I received (9) 

 Eisenia foetida, and in revising the material found also (10) D. 

 arbor ea. In April a further consignment brought me, in addition 

 to the foregoing, (11) D. mammalis (= celtica), a form which I 

 have named (12) A. cambrica, which needs revision in the light 

 of modern research, and a species of Octolasium, which must be 

 referred to (13) O. profugum, because the tubercula extend over 

 segments 31-34. Eight of the foregoing species reached me 

 again on June 7th, 1892. One or two other species of a critical 

 character still remain doubtful, but it seems pretty clear that 

 constricta, putris, and eiseni are to be found there. Total 

 record 13. 



30. Northumberland. — The only records for this county 

 known to me are found in Dr. Johnston's ■ Catalogue of British 

 Worms,' published in 1865. Some of these it is difficult to 

 determine, but it seems clear that six species were then known. 

 In the terms of modern science these may be given as : (1) L. 

 terrestris, (2) L. rubellus, (3) A. longa, (4) A. chlorotica, (5) Eisenia 

 foetida, and (6) L. festivus. These are credited to Dr. Johnston 

 himself, who found them at Berwick. Total record, 6. 



31. Nottingham. — This county has received a good deal of 

 my attention, largely through the kind aid of Prof. Carr, M.A., 

 and I am publishing my results from time to time in the ' Trans, 

 of Notts. Nat. Society.' Pieference may be made to this publica- 

 tion for details (1910 and following years). The list contains : — 

 (1) Allurus tetrcedrus, with var. luteus, Friend, (2) Eisenia rosea, 



(3) E. foetida, (4) A. caliginosa, including both turgida and
