path, &c. Mailer's figare does not appear to me to be a good one of this species.

8. C. Joanna. Nova species. PI. III. fig. 8. — Pool near Abbey St Bathans. 



Shell roandish, ovate, narrower anteriorly than posteriorly ; of a brown coloar, 

 with an orange mark across back of shell and lower margin ; shell beset all 

 roand with rigid hairs, and covered with minute black points or dots ; setae of 

 antennvB namerous, about twelve or more. Resembles C. vidua a good deal in 

 shape, but differs totally in colour and markings. Differs from C.pilosa somewhat 

 in shape, and in not being glabrous, but marked all over with black roughish- 

 looking points. 



9. C. minuta. Nova species. PI. III. fig. 9. — Pool on Beaumont Water at 



Yetholm. Shell broader posteriorly than anteriorly ; elevated and rounded on 



upper margin ; slightly sinuated on under margin ; hairy all round ; of a light 

 brown coloar with a tinge of green ; body of shell smooth, shining ; posterior legs 

 terminated by one long claw ; anterior legs famished with a pencil of long hairs 

 from penultimate joint, and terminated by several strong hairs or setas ; sette of 

 antenna3 numerous. 



10. C. elongafa. Nova species. PI. III. fig. 10. — Pool on Beaumont Water at 



Yetholm. Shell much broader at anterior than posterior extremity, which is 



narrow and much elongated ; elevated on upper margin towards anterior extre- 

 mity, and sinuated on under margin more towards the posterior extremity ; white ; 

 transparent ; hairy ; setae of antennae five or six ; anterior feet of about three 

 articulations, each articulation furnished with setae ; jDosterior legs denticulated. 



11. C. repfans. Nova species. PI. III. fig. 11. — Yetholm Loch. Shell long 



almost elliptical, nearly plane on upper, and slightly hollowed out or sinuated on 

 under margin, rather ventricose, hairy ; densely ciliated on anterior extremity ; 

 the ciliae on posterior extremity 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 the shell ; antennae and feet short in comparison to the 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. 



12. C. Westwoodii. Nova species. PI. III. fig. 12. — Yetholm Loch. Shell 



much deviated and rounded on upper margin, and sinuated on lower, broader at 

 anterior extremity, green-coloured, semi-transparent, densely covered with pretty 

 long hairs all over; second last joint of anterior feet furnished with a pencil of 

 long hairs ; posterior feet furnished with a short seta at each articulation, and 

 with a long curved claw at extremities ; antennae indistinctly articulated. 



13. C. tristriata. Nova species. PI. III. fig. 13. — Pond at Little Swinton. 



Shell ovate, ventricose, anterior extremity a little narrower than posterior, upper 

 margin rounded, lower sinuated slightly, green, hairy ; on the upper margin, 

 nearly in middle of length of shell, there is a dark mark, from which run to 

 posterior extremity three dark green streaks, the centre one of which is the most 

 distinct and the darkest coloured ; anterior extremity of a rather darker green 

 than the i-est of shell. Betv^een the centre and most anterior of the streaks are 

 five or six small lucid spots. 



14. C. hispida. Nova species. PI. III. fig. 14. — Pool on Beaumont Water at 

 Yetholm. — ■ — Shell almost elliptical ; the anterior extremity being a little broader 

 than posterior : rather ventricose ; very roughly and densely hairy ; of a brown 

 colour all over, with one or two dark brown marks running across centre of shell, 

 in the anterior of which are foar or five translucent spots ; both extremities of a 

 darker colour than other parts of shell. The whole shell is very hispid, spines 

 rather than hairs covering the shell; antenna slender; setae seldom much divari-
