Cypris fusca, Desmarest, Cons. Gen. sur les Crust, p. 384. 1825. 



Shell oval ; of a brown-colour, reniform ; anterior extremity nar- 

 rower than posterior, which is rounded and broad ; shell covered 

 with fine hairs ; anterior feet provided with three long filaments ; 

 the rounded posterior extremity and brown-colour sufficiently dis- 

 tinguish this species from Muller's Candida. 



Sp. VIII. Cypris reptans. — Plate V. Fig. 5. Testa elongata, 



stricta, maculis magnis viridibus notata. 

 Habitat. — Yetholm Loch, Roxburghshire. — Newham Loch, Northumberland, 

 Dr Johnston. New river, London. 



Synonimes — Cypris reptans, Baird, Trans. Berw. Nat. Club, p. 99, pi. iii. fig.

" Shell long, narrow, almost elliptical, nearly plane on upper, 

 and slightly sinuated on under margin ; rather ventricose ; hairy ; 

 densely ciliated on anterior extremity ; the cilise on posterior extre- 

 mity fewer, but much longer ; of a light colour, with dark-green 

 markings, which appear to be rather irregular ; both extremities 

 have a large broad green spot, which send out processes as it were 

 towards the centre of shell ; antennae and feet short in comparison 

 with size of shell. I have never seen this species swimming about 

 in the vessel in which I have kept it, but always creeping on the 

 bottom," — hence its name. — Filaments of anterior feet few and very 

 short. 



Sp. IX. Cypris hispida — Plate V. Fig. 6. Testa ovata, fusca, 

 hispida. 



Habitat. — At Yetholm, Roxburghshire. Ditch near Surrey Zoological Gar. 

 dens, London. 



Synonimes — Cypris hispida, Baird, Trans. Berw. Nat. Club, p. 99, pi. iii. 

 fig. 14. 



" Shell almost elliptical; anterior extremity a little broader than 

 porterior ; rather ventricose ; very roughly and densely hairy ; of a 

 brown-colour all over, with one or two dark brown marks running 

 across the centre of shell ; both extremities of a darker colour than 

 other parts of shell ; the whole shell is very hispid, spines rather 

 than hairs covering the shell ; antennae slender ; setae seldom much 

 divaricated." Filaments of anterior feet, if any, consist only of two 

 or three short hairs, as in Candida and Reptans ; and like them, 

 this insect is generally to be found at the bottom of the vessel in 

 which it is kept. This circumstance would seem to favour J urine's 

 opinion of the important use the anterior feet serve for progressive
