BOTANICAL AND CONCHOLOGICAL NOTES. 



Localities. — Yoredale : Fourstones, Northumberland ; Hurst, 

 Yorkshire. Scar Limestone series, Redesdale. 



These are the whole of the Entomostraca that I can thoroughly 

 identify in these Upper Shales. There are a few other forms, but as 

 these are not sufficiently characteristic for the purpose of identifica- 

 tion, I think it far better for Palaeontological science to hold them in 

 abeyance than to load my text with a series of objectionable names. 



I have now the Foraminifera and the miscellaneous organisms to 

 refer to, and then — probably in one more article — I shall have 

 completed the task to which I set myself.

BOTANICAL NOTES. 

 Lathrsea squamaria near Dewsbury. — Whilst rambling along a 



lane between Dewsbury and Mirfield a week or more ago, I casually noticed a few 

 white-looking tufts in a coppice, and on climbing over the wall was surprised to 

 find some 30 or 40 flowering stems of this curious parasite in full bloom. I believe 

 this is the first time the plant has been recorded for this part of the West Riding, 

 and it may be noted that it was not growing on hazel, as the text-books usually 

 give it; but on sycamore. — C. P. Hobkirk, Dewsbury, 20th May, 1885. 



Elder growing upon a Willow. — On 21st of March last I came across 

 an example of an Elder growing upon a Willow, which, I think, is worthy of note. 

 Near one of the by-washes of the canal here, stands a large and much-decayed 

 Willow. As is usually the case, a quantity of rubbish has collected upon the 

 decaying portion of the tree, and from this, about 4 feet from the ground, grows an 

 Elder, with trunk of considerable size, and measuring in height about 8 feet. This 

 Elder must have lived a long time upon the nourishment drawn from the decaying 

 Willow and the rubbish collected thereon, though now one of the arms of its root 

 (which has exceeded 4 feet in length) has found its way into the ground. — H. 

 W^ALLis Kew, Louth, 4th April, 1885. 



CONCHOLOGICAL NOTES. ■ 

 Occurrence of Limax cinereo-niger in Washburndale.— 



I have the pleasure of recording the occurrence of the tenth specimen yet known 

 for Britain of this extremely rare slug. On the 5th of July, while with Mr. Clarke 

 and Mr. R. Rosenstock in Washburndale, we came to the point where the Glaston 

 Beck flows into Lindley Wood Reservoir, Here there were numerous planks 

 lying on the ground, the remains of a dismantled building. Turning these over, 

 we found slugs in great abundance, including Lhnax agrestis and its varieties, 

 Limax Icevis, Avion ater var, riifa, two or three Limax maximits var. cellaria. and 

 the greatest treasure of all, a single, half-grown example of L. cinereo-itige?: Its 

 characters were unmistakable — the trifasciated foot, light keel-line and coarse 

 rugosities amply sufficing to separate it from L. inaximiis. In another locality 

 close by we found more slugs, and with them a large quantity of Zo7iiies ftilviis. 

 The district is not usually a productive one for land shells, being underlaid 

 by sandstones and shales of the millstone grit series, — W. Denison Roebuck, 

 Leeds, July loth, 1885, 



Achatina acieula at Knottingley.— Referring to Mr. Emmet's fine 

 paper in the N'atiiralist of July, I am happy enough to bear testimony to the truth 

 of his theory as to the occurrence of A. acictda. Being at Knottingley, I recollected 

 and applied his hints, w^entto a likely place near the station, and immediately found 

 the shell quite fresh, and in sufficient numbers not to be accidental, just as 

 Mr. Emmet expected. — R. D. Darbishire, Manchester, July 19th, 1885.
