8. C.Joanna. Nova species. PL III. fig. 8. Pool near Abbey StBathans. 



Shell roundish, ovate, narrower anteriorly than posteriorly ; of a brown colour, with 

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

 rigid hairs, and covered with minute black points or dots ; setae of antennae nume- 

 rous, about twelve or more. Resembles C. vidua a good deal in shape, but differs 

 totally in colour and markings. Differs from C. pilota somewhat in shape, and in 

 not being glabrous, but marked all over with black roughish-looking points. 



9. C. mint/to. Nova species. PL III. fig. 9 Pool on Beaumont Water at Yet- 



holm. Shell broader posteriorly than anteriorly ; elevated and rounded on upper 



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

 with a tinge of green ; body of shell smooth, shining ; posterior legs terminated by 

 one long claw ; anterior legs furnished with a pencil of long hairs from penultimate 

 joint, and terminated by several strong hairs or setae ; setae of antennae numerous. 



10* C. elongata. Nova species. PL III. fig. 10. Pool on Beaumont Water at Yet- 

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

 and much elongated ; elevated on upper margin towards anterior extremity, and 

 sinuated on under margin more towards the posterior extremity ; white; transpa- 

 rent ; hairy ; setae of antennae five or six ; anterior feet of about three articulations, 

 each articulation furnished with setae ; posterior legs denticulated. 



11. C. reptans. Nova species. PLIII.fig.il 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. Wettwoodii. Nova species. PL III. fig. 12._Yetholra Loch Shell 



much elevated 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. PL III. fig. 13. Pond at Little Swintou 



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

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

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

 rior extremity three dark green streaks, the centre one of which is the most dis- 

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

 the rest of shell. Between the centre and most anterior of the streaks are five or 

 six small lucid spots. 



14. C. hutpida. Nova species. PL III. fig. 14 Pool on Beaumont Water at Yet- 



hnlin. 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 four or five translucent spots ; both extremities of a darker 

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