THE ESSEX FIELD CLUU. 253 



low-net, chiefly by Messrs. Filch, Crouch, andW. Cole ; but the swirl of the water 

 as the barge was pulled along hindered the success of their endeavours; and as 

 Mr. Crouch opined, better results would probably be obtained by carefully work- 

 ing in the more quiet backwaters. In Mr. French's paper in the Essex Naturalist 

 (vol. ii., pp. I and 46), many species are recorded from the Chelmer near Felstead. 

 The results of the day's work were rather disappointing, only eighteen species being 

 on record, as shown in the following list. Nearly all of these were taken alive, 

 and were exhibited in a small aquarium brought for the purpose. A considerable 

 number of caddis cases (Phryganida;) were observed on the water weeds, some 

 formed of stones, twigs, &c., whilst others were thickly covered with adherent shells, 

 chiefly of Sp/nrrmm.

Some interest was evinced in two Musk Beetles (^Aromia moschata) that were 

 taken off the pollard willows. Only one butterfly, Vanessa to (the Peacock) was 

 seen. Our President boxed several moths off the tree-trunks. — the "Yellow-tail" 

 (^Liparis aurifiua'). the " Dagger " (^Acronycta psi), the " July Highflyer" (^Ypsipetes 

 elutala') being the most abundant. As the tow-rope swept over the reeds and 

 sedges many moths and Phryganids, &c., were disturbed but not secured. The 

 " Scorpion Fly " (^Panorpa communis') was also abundant, and its curious structure 

 attracted notice. 



During the afternoon, Mr. T. V. Holmes, F.G.S., read a very interesting 

 paper on " The Geology and Scenery of the Club's Voyage from Maldon to 

 Chelmsford, August 8th, 1891," already printed in the Essex Naturalist (atite^ 

 pp. 197-202.) The paper was illustrated with geological maps and sections. 



Cordial votes of thanks were passed to all who had assisted in the success of 

 the meeting. 



Most ample provision of light refreshment was provided on board by our kind 

 "skipper," Mr. Fitch, and somewhat late in the afternoon a combined luncheon 

 and tea was partaken of in the garden of the Paper (Livermore's or Huskett's) 

 Mill, the use of which was kindly granted by Mr. Pharaoh Byford. 



After luncheon, an ORniNARV Meeting (the 126th), was held for the pro- 

 posal and election of new members, Mr. Fitch, President, in the chair. 



The following were duly elected : Messrs. J. H. Chapman-Coombs, A. H. Gray, 

 and C. F. Osomond. 



On the motion of the President, a special vote of thanks was passed to Mr- 

 Byford and family, for allowing the luncheon to be served in their grounds, and for 

 their kind aid in many ways given in the arrangement of the details of the meeting.
