NOTES MOLLUSCA. 



as the author says in the preface, ' as character-sketches rather than 

 as portraits, and having no pretensions to scientific accuracy or 

 artistic merit.' We must take exception to this depreciatory remark by 

 saying that not only do they show special merit, but the subjects 

 delineated, we can testify, are absolutely accurate in detail, such as 

 could only be executed by one who was intimately acquainted with 

 the birds in their haunts. When all are good alike it is invidious 

 to make a distinction, but we would particularly draw attention to 

 the black-breasted Golden Plover on the fell-side, at page 40 ; the 

 group of startled Black Game on the moor-dyke; punting amongst 

 the ice-floes on the coast, at page 168 ; the long line of Brent Geese 

 on the feed, at page 200 — note the life-like attitude of the birds 

 when feeding, with the reflection of their darker parts in the sloppy 

 ooze. The sketch of Grey Geese on the sand-bar ('full sea') also 

 is admirable — in long-extended rank within the wash of the tide, 

 suggestive of a regiment on parade standing at ease. 



In concluding these remarks on Mr. Chapman's pleasant volume 

 we trust we have said enough to induce our readers to become 

 acquainted with it and judge for themselves, and we feel quite 

 certain the perusal will afford them much satisfaction. — J.C. 



NOTES— MOLL USCA. 



Variation in Helix nemoralis and H. hortensis at Rothwell, Mid- 

 West Yorks. — On July 2ist I collected a number of Helix nemoralis and 

 H. hortensis from a bank on the Leeds and Pontefract road near Rothwell, the 

 reds and yellows being about equal. The species were intermixed. The//', nemoralis 

 included fine polished specimens of var. rubella 00000 and 02345, var - petiveria 

 00000 and 00300, and var. libelhtla 00000, one of which has a pale-pink inner 

 and outer lip. The hortensis include var. lutea 00000, and var. coalita Moq. — 

 a common variety here, but uncommon in nemoralis — and the type. All have 

 the spire raised. — Geo. Roberts, Lofthouse, August 12th, 1889. 



Some North of England Mollusca. — Looking over an old note-book I find 

 a few unpublished records which are possibly worth saving from oblivion ; they all 

 refer to specimens examined by myself. Physa hypnorum var. intermedia Locard, 

 Cumberland (Smith) : this is an abbreviated form of the species ; I never heard 

 exactly where the specimens were found, they were sent to my brother. 

 Syndosmya prismatica, Seaton Carew, one example (Rev. J. W. Pattison). Helix 

 nemoralis v. rubella o.,3 4455 , rubella o : .4 : , and rubella 00305, Kiveton Park, 

 Yorks. (Rev. H. Friend). H. nemoralis var. libelhtla oo3 4 o, Beeston, Cheshire 

 (Rev. H. Friend). Paludina fasciata (=vivipara Auctt.) var. producta Pascal, 

 3I7F mill, long, near Wakefield (G. Roberts). Limax agrestis v. obscura Moq., 

 Wakefield (Wilcock). Helix caperata var. attentat a Ckll., Stanley (G. Roberts). 

 H. nemoralis v. libellula o. 2 (34) s , Lofthouse (G. Roberts). H. nemoralis v. 

 libellulo-rubella 00000, apex of shell yellow, body whorl pink ; and var. libellulo- 

 rubella 00300 with variation in the colour of the animal, the exposed portion of 

 mantle being yellow instead of grey, Lofthouse (G. Roberts). H. hortensis v. 

 lilacina 00000, with five erosion-bands : from G. Roberts, locality not stated.
