Paludestrina jenkinsi in Spen Valley. — I found this 

 mollusc on 12th June in the Hunsworth Wood district of Spen 

 Valley in the upper part of the river Spen, w^here it occurs in 

 profusion on Potaniogeton crispiis and also in the sunken grass 

 roots at the edges of the stream, which is here about tw^o yards 

 wide and two feet deep. The nearest localities are Dukinfield 

 (Cheshire) and Droylsden (Lancashire), w-here it is found in the 

 canals. The Spen enters the Calder some 3^ miles from 

 Hunsworth Woods, and several weirs intervene betw-een that 

 place and the confluence ; the nearest canal is at Brighouse, 

 some four miles away on the other side of the ridge, and this 

 joins the Calder three miles higher than the Spen. (The Calder 

 is connected with the Dukinfield district by canal via the Stan- 

 edge tunnel. — Ed.) I have visited the place three or four times 

 a year for the last four years, but had not seen any trace of 

 them until this, my first visit this year. Only about one per 

 cent, are carinated, and these not very decidedly on all the 

 whorls ; a good proportion are of large size compared with 

 specimens from Grimsby. Several mills higher up the valley 

 turn their w^aste water into the stream and thus it is not a clear 

 one, though occasionally on Sundays the bottom may be seen. —
