for trout. It is extremely common in manure heaps com- 

 posed of cow-dung. — L. xanthurus. Of a bright red, the 

 apical rings yellow. This is the gilt-tail of anglers, and is 

 found among rotting oak bark, in old hot-beds and melon 

 frames. — Gordidnus. Of a pale rosy red. Common in cul- 

 tivated sandy ground, where it is uniformly found contorted, 

 assuming the appearance of a very intricate knot. — L.lividus. 

 Of a dull red, varied with dull purple and greenish. Com- 

 mon in gardens. — L. omilurus, O. rubescens Temp. MSS. 

 Body long, contractile, cylindrical, with a compressed lan- 

 ceolate apex, unfurnished with a belt at the position of the 

 sexual organs, each ring with very small spines projecting 

 backwards. Common in rich grounds, generally where 

 docks grow. I am not disposed to concur in the necessity 

 of erecting this into a genus ; but the characters separating 

 it from the preceding species are obvious enough. It is never 

 larger than half the size of L. terrestris ; and is of a bright 

 reddish brown, with the hinder part, or apex, very flat. R. T. 



— Clitellio Sav. minutus Fab. ? At Cranmore, among 

 moss: see VII. 131. [With respect to this little animal, 

 it is suggested, in VIII. 260<, on the ground of a remark 

 from Dr. Johnston, that it may be a larva.] — Stylaria 

 Lam. lacustris Lin., S. paludosa Lam. At Cranmore, 

 in the pond, not uncommon ; March, 1811. — Nais Lin. 

 Cuv. t>ermicularis Gm. Common at Cranmore, in the pond. 



— N. serpentina Gm. At Cranmore: see VII. 130. [In 

 VIII. 260., is a suggestion, derived from Dr. Johnston, that 

 this may be a larva.] — Tubifex Lam. rivulorum Lam., 

 Z/umbricus tubifex Mull. It forms tubes about 1$ in. high, of 

 the soft black mud at the sides of slowly running rivulets : 

 these tubes lie contiguous to each other. [In VIII. 620, 

 621., is information on iumbricus tubifex /3 Mull., and 

 references to farther information on it in this Magazine : it 

 may be that this variety exists in Ireland as well as in Eng- 

 land.] 



I, ii/irudo Lin. sanguisuga Lin. Extremely common. — 

 Erpobdella Blainv. (Nephelis Sav.) stagnalis Lin., biocu- 

 lata Miill.,Gm. In spring water at Cranmore; June 23. 1816. 



— E. complanata Gm. In Lyster's spring; June, 1808. — 

 E. crenata? Trans. Lin. Soc, ii. 318. t. 29. Of a pale 

 green colour ; head distinct from the body, with two eyes ; 

 body divided into segments, each so rounded laterally as to 

 make the sides appear deeply crenated. Found among 

 Confervas in a ditch at Whitehouse; Aug. 1807. Young 

 ones were observed adhering to the body of the parent. It 

 agrees exactly with Turton's description : see his iv. 71. —
