Manchester Crtptogamic Society. — Ordinary meeting, the president 

 (Mr. John Whitehead) in the chair. — The honorary secretary (Mr. Thos. 

 Rogers) having read some interesting correspondence, the president 

 exhibited a specimen of the rare Zygodon SHrtoni, Schm., (Z. aristatus, 

 Lindb.j with young fruit, lately gathered by Mr. Percival near Barmouth, 

 in company with the president and Messrs. Ashton and Nield. The 

 plant is closely allied to Z. viridissbmis, differing from it chiefly in the 

 excurrent nerve, in growing on rocks and not on trees. The occurrence 

 of a variety of Mastigohryiun deflexum, Nees. , at Tjm-y-Groes, near 

 Dolgelly, was reported by Mr. W. H. Pearson, and a specimen gathered 

 by him in company with Dr. Carrington on the 12th of April, was 

 exhibited. Another rare cryptogam exhibited by the president, was 

 Zygodon Novcellii, so named by Professor Schiniper in honour of its 

 discoverer the late J ohn jS'owell of Todmorden, but described formerly 

 by Mr. Wilson under the name of Z. gracilis ; the specimen was received 

 from Mr. West, who gathered it at Ingleborough last Easter. INIr. Rogers 

 exhibited specimens of a number of Indian ferns which had been collected 

 on the Himalayas, which were interesting on account of their identity with 

 species indigenous to Britain ; amongst them were Cigstopteris fmgilis, 

 Asplenium septentriunale, A. fontanum and A. AdAanturn-nigrum. The 

 president mentioned that he was mistaken in his siu-mise aboat the 

 T. Barnhergeri mentioned at the last meeting.

 exhibited two species of parasitic fungi, (Ecidium tragopogonis and 

 Puccinea glomerata, from Southport — the first upon the leaves of Trago- 

 pogon pratensis, and the latter infesting those of Senecio J acohoea. Several 

 mosses, also from Southport, were exhibited by Mr. Holt, including 

 Meebia uliginosa, Bryurn calopliyllum, Hypnurn lycopodioides, H. polyga- 

 rnv/in, and H. Wilsoni ; very fine specimens of Bryum turhinatum, from 

 Clifton, were shown by Mr. J. Makin ; and ]\Ir. C. Wild brought some 

 rare HepaticcE which he had gathered during the preceding week in Cum- 

 berland. One of these was Lejennia ovata, from Lodore, a species not 

 previously known to grow in England. The hon. secretary (Mr. Rogers) 

 informed the meeting that he had been with the president and a party of 

 friends in West Yorkshire, but had returned in order to attend the 

 present meeting. They found some mosses still unripe and unfit to 

 gather, on account of the severity of the past winter ; but others were in 

 beautiful condition, and he had the pleasure of exhibiting Encalypta 

 ciliato., Mntum serratum, Bartramia gracilis, Leskea rufescens, and one or
