beginning of September. Where the left-hand hedge-bank is wet 

 and foundering, P. palustris and gracilis harbour among nettles and 

 on hazel, in May ; and the latter in autumn is associated with extricata 

 and compta. Towards the foot of the hill on the same side the bank 

 is strengthened by a retaining wall, open to the sun and coated with 

 Marchantia, where water leaks through from the field, or trickles from 

 a rustic spout overhung by Geranium and Scolopendrium. Here, from 

 May onwards, P. pulclira and trifasciata are to be found. The 

 drainage from the lane and spout ripples down a shallow trench 

 amongst Spircea ulmaria, Jlelosciaditlm, and 3£entha aquatica, mingled 

 with rotting leaves ; Ulomyia is in profusion, in company with P. 

 trivialis. On entering the hamlet, the road divides, and the right- 

 hand turning, bordered on each side by a shallow ditch of gently 

 flowing water, is flanked by a garden hedge on the left, facing the sun, 

 opposite a high, damp, shady bank, much encumbered with nettles, 

 and partly bordered with Chrysosplenium. The herbage by this shady 

 ditch, early in June, sheltered plenty of P. notahilis and morula, 

 \f\i\ifusca sparingly. The sunny ditch opposite, choked wnth Veronica 

 heccahunqa and watercress, abounds with P. canescens and trivialis, 

 and during early summer and autumn with P . fratercula. Ju the 

 pastures nearest to the hamlet, by the stream into which the lane and 

 ditches drain, P. soleata was common in June at one or two miry 

 places by the water near a rustic bridge, among Epilohium hirsutum 

 above the bridge, and in a swampy hollow under some oak trees just 

 below. P. ocellaris is common all over this district, especially along 

 wet hedge-ditches, not too much obstructed with rotting leaves. 

 Sometimes it abounds in wet meadows and lanes amongst Juncus com- 

 munis and Iris pseudacorus. 



About a mile and a half from Wincanton, the railway to Bath 

 passes Moorhays Farm ; and shortly beyond that is a level crossing 

 leading to Knowle Park Farm. The ditch on the left-hand of the 

 railway embankment, where it is shallow and the water ripples gently 

 amongst Sparganium ramosum and Selosciadium along its clayey 

 channel, is the resort of P. soleata, morula, axidifratercida, in May and 

 June, and of the last species in August and September. Near the 

 culverts, further on, through which the water crosses under the line, 

 P. incerta occurs in May, June, and August. Along streams and 

 rivulets in this neighbourhood, and in Blackmoor Vale, P. exquisita, 

 fallax, hlandula, and trifasciata, are plentiful from May onwards, 

 especially near clay banks, &c., clad with Marchantia, where the flow 

 of water is brisks In September, P. compta is common on hazel in
