270 JOURNAL OF CONCHOLOGY, VOL. 9, NO. 9, JANUARY, 19OO. 



preparation of this work must have been enormous, and it is still 

 indispensable to all workers on systematic conchology. 



The 'Conchologia Indica' was merely a pictorial work, and although 

 of considerable usefulness, leaves much to be desired in the finish of 

 the illustrations. For this, however, the publishers were responsible 

 rather than the author. Mr. Hanley's other separate works have been 

 practically superseded by more modern monographs, but still call for 

 frequent reference. 



The monographs of TelHna, Nuculidcz, and Solarium in the ( The- 

 saurus Conchyliorum' are beyond question among the best in that 

 work. Of the thirty-five descriptive papers, twenty-seven treat upon 

 bivalve shells. The Pelecypoda had special attraction for Mr. 

 Hanley, indeed one of his separate works was devoted entirely to 

 their description. Attention should also be called to one of his mis- 

 cellaneous papers in the Journal of Proceedings of the Linnsean 

 Society, vol. iv., pp. 43-90, entitled "On the Linnasan Manuscript of 

 the Museum Ulricae," being a companion work to his treatise on the 

 'Ipsa Linnaei Conchylia.' 



Sylvanus Charles Thorp Hanley was born at Oxford on 

 January 7th, 18 19, and, after leaving school, proceeded to Wadham 

 College, Oxford, and in due course obtained his B.A. He subse- 

 quently became a student-at-law of the Inner Temple, but inheriting 

 ample means from his father, he had no occasion to complete his 

 legal studies. He was twice married ; one of his sons survives him, 

 but an elder one died some years ago. He was elected a Fellow of 

 the Linnean Society in 1843. Conchology appears to have been his 

 hobby practically all his life, and therefore it is not surprising that he 

 got together a very large collection of shells, the value of which is 

 enhanced by having been named by so eminent and careful a worker, 

 and doubtless many important comments will be found upon the 

 wooden tablets to which the specimens are attached. He died at 

 Penzance on April 5th last, aged eighty years, and was interred there 

 on the 10th of the same month. 



Note on the appearance of Helix virgata in Herefordshire. — My first 

 acquaintance with Helix virgata in this county was two years ago when I took the 

 variety hitescens. Last year, I again met with the type and two vars. (Jutescens and 

 albicans) in my garden on the outskirts of Ross. I have given specimens for com- 

 parison to several friends, and on Oct. 12th one of my assistants informed me that 

 while cycling that morning after rain his notice was attracted to a crackling sound 

 from beneath the tyres of his machine. This he found to be due to a number of 

 small snails, which turned out on examination to be H. virgata, spread over the road
