yellowish ; each side of the body striped with a dark brown line, com- 

 mencing faintly near the tentacles and converging on the keel ; foot pale 

 yellow. Locality : Hedge Banks, Nelthorpe, Banbury, Oxon. I am not 

 aware of any previous record of such a variety as the above, banded forms 

 of flavus being, I believe, very rare. Mr. T. D. A. Cockerel! informs me 

 that Limax calendymus, Bourg., from Madeira, — which he thinks is pro- 

 bably a variety of L. flavus, — exhibits an arrangement of the markings 

 approaching banding, but is distinct from that for which the name Uneolata 

 is now proposed. I found the first specimen of it in a hedge bottom, and 

 about a week afterwards I found another in a garden, with the band rather 

 broader but less distinct. — W. E. Collinge, Hon. Assist. Curator Conch.

SCIENTIFIC SOCIETIES. 



Linnean Society of London. 



March 6, 1890.— Mr. Carruthers, F.R.S., President, in the chair. 



Mr. S. Lithgow was admitted, and Messrs. J. Lowe, E. R. Waite, and 

 G. F. Elliott were elected Fellows of the Society. 



Mr. Thomas Christy exhibited a dried specimen of Picramnia anti- 

 desma, the plant from the bark of which a medicine known as Cascara amarga 

 is believed to be prepared, and which is a useful alterative in diseases of 

 the blood and skin. 



Mr. J. E. Harting exhibited a series of horns of the American Prong- 

 buck (Antelocapra Americana), to illustrate the mode in which the sheddiug 

 and new growth of horn is effected in this animal. 



A paper was read by Mr. D. Morris, on the production of seed in 

 certain varieties of the sugar-cane, Saccharum officinarum. It was pointed 

 out that, although well known as a cultivated plant, the sugar-cane had 

 nowhere been found wild ; nor had the seed [caryopsls) been figured or 

 described, it being the generally received opinion that having been propa- 

 gated entirely by slips, or cuttings, it had lost the power of producing seed. 

 Spikelets, however, received at Kew, had been carefully examined and the 

 seed found, which was now for the first time exhibited by Mr. Morris. 

 He anticipated that, by cross-fertilization and selection of seedlings, the 

 sugar-cane might be greatly improved ; and much importance was attached 

 to the subject, as it opened up a new field of investigation in regard to 

 sugar-cane cultivation, Mr. J. G. Baker and Mr. T. Christy concurred. 



A paper was then read by Mr. Spencer Moore, on the true nature of 

 Callus. Part I. — The Vegetable Marrow and Ballia callitricha. It was 

 shown that the callus of sieve-tubes of the vegetable marrow gives marked
