the flowering plants. Eqidsetum iimosiim, one of the vascular 

 cryptogams, was growing in a great mass in one of the ponds, and 

 many of the shoots bore fertile cones, a few of which were, after 

 some difficulty, obtained for examination. 



The aquatic Mollusca received attention at the hands of Mr. R. A. 

 Adkin, who found Planorbis coviplanatiis^ P. vortex, Liiiincea 

 paiustris, and L. ti'uncatiila. He hoped that amongst the P. 

 vortex might be some Z. spirorbis, but was disappointed. Z. 

 truncatula I generally look upon as fairly good, perhaps only because 

 I have seldom found it. 



A Trichopteron (caddis-fly) taken and given to me was 

 Limnophilus auricula. Two or three Diptera were taken and 

 sent to Mr. Colbran J. VVainwright for identification. They were 

 Bibio marci, ^ , B. veiiosus, ^, (^ , and Syrphus bifasciatus. To B. 

 venosus, however, a query is attached. Of two Hymenoptera taken, 

 one was a $ of the genus Perithous, and the other was an 

 Iclmeiimon. 



Mr. West, of Streathani, collected material for the microscope, and 

 reports: — (i) Cellular Cryptogams: Spirogyra, Closterium, and 

 Volvox globator ; (2) Rotifera (besides several free-swimming 

 species) : Melicerta ringens, Ploscularia corntita, Scaridiuvi longi- 

 amdum, and Rotifer vulgaris ; (3) Vorticell?e : Epistylis vagini- 

 cola, and Vorticella ticbulifera ; (4) Entomostraca : Cypris, Cyclops 

 (/uadricornis, and Chydorus sphericus ; (5) he also found Hydra 

 vulgaris, statoblasts of Polyzoa (species not recognised), and great 

 numbers of larvae of Pplicmcris. 



As regards the Lei)i(loptera, Mr. JJishcjj) and others searched the 

 Genista anglica for larvre of Pseudoterpua pruinata (= cytisaria) with 

 some success. Mr. l^>ishop also reports an Adela captured, and 

 larvai of Cheiinatobia brumata ; Oporabia dilutata ; J'higalia pedaria 

 (= pilosaria) ; Orthosia lota ([)robably) ; Ppunda viminalis 

 (probably), and a species of Xanthia. Other lepidopterists seem to 

 have neglected their opportunities, or perhaps the postal authorities 

 dealt unkindly with their contributions ! 



If the weather was bad, the catering at the Merrilands Hotel was 

 not, and justice was done to the excellent tea provided. The wind 

 having fallen in the evening, the walk back to the trains at Effing- 

 ham Station was rather enjoyable than not, and on the whole the 

 memory of the excursion — which, by the way, has become historic, 

 owing to Mr. Step's article in the August number of " Pall Mall " — 

 will not perhaps be an unpleasant one after all.
