History of British Entomostraca. 135 



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, raaculis 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 ciliae 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 Siu-rey Zoological Gar- 

 dens, London. 



Synonimes — C3T>ris 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 Jurine's 

 opinion of the important use the anterior feet serve for progressive
