liRITISH ANNELIDS. 189 



on the 31st segment, and the ch'tellar papillre {tubercula pubertaiis) 

 arc on segments 28, 29, 30. The under side of segment 16 is tumid, 

 so that it may easily be mistaken for the 15th, which carries the 

 male pores. Other segments are also frequently marked by similar 

 tumidities. 



Forma arborea, Rosa, seems scarcely a distinct species, although 

 it has been so ranked. It has papillae on two girdle segments (29, 

 30), and is smaller than the type. In every other respect they seem 

 to be identical. I have specimens of this form from Epping Forest. 



Yoxxwxconstricta^ Rosa, has also been reckoned a distinct species ; 

 but I have examined a series collected in Sussex by the side of a 

 set kindly presented to me by Dr. Rosa himself, and I fail to see 

 any real difference, except in the constriction of the segments. 



Var. palksceiis^ Friend, is the true " Gilt-tail " of the angler, and 

 sometimes attains a considerable size. It is very much lighter than 

 iny of the other species and varieties, and exceedingly delicate-looking. 

 It emits a large quantity of yellow fluid when irritated, and is a most 

 useful worm for bait. I have received a very fine set from Mr. Allen, 

 collected under old rags where manure is deposited at West Ham. 

 I have also had either the type or one of the forms from Woolwich, 

 Chingford iarborea), through the kindness of Mr. W, Allen; and 

 from Bushwood and other parts of Epping Forest, through Mr. George 

 Day, F.R.M.S. 



I append a tabular view, marking with an asterisk those which 

 are at present on record for Essex. I am sorry that I cannot con- 

 gratulate my readers on their enthusiasm, or the efforts they put 

 forth to make the worm-fauna of this county better known. If 

 they had a tithe of the zeal of my Irish correspondents — who have 

 added several new species to our lists, we should be able, probably, 

 to fill up nearly all the blanks which still remain in our catalogue. 



I have received a very interesting acjuatic worm [Dic/ueta cur- 

 vise^osa, Friend) from Chelmsford, which I hope shortly to figure 

 and describe in The Essex Naturalist. Meanwhile, I once more 

 appeal for living specimens, sent in tin boxes filled with moss, and 

 addressed 4, The Grove, Idle, Bradford.
