A New Variety of the Celiar-slug — Limax flavus 

 var. sufFusa. — By this name I propose to characterize a re- 

 markably interesting specimen of Limax flavus, taken at EaHng, 

 Middlesex, May 3rd, 1885, by Mr. Sydney C. Cockerell, and 

 most obligingly sent me by that gentleman. The description 

 will stand thus : — 



Limax flavus var. sufFusa, 

 animal with the shield and body suffused with a uniform dark 

 tinge, caused by the coalescence of the dark markings. The 

 varietal name is intended to signify that the dark markings of both 

 shield and body are fused together into a uniform ash or dark- 

 lead colour, shading off into a lighter tint towards the foot. 

 Owing to this fusion of the markings there is no trace whatever 

 of any pattern, and the animal is altogether of the uniform tint 

 described. The specimen is a moderately adult one, and is now 

 preserved in spirit. It should be remarked that the specimen is 

 not only of the variety I now describe in respect of its markings, 

 but it is also of my var. grisea in respect of its colour, and should 

 appear in any county or other list as ' Limax flavus var. suffusa 

 -)-^mm,' if precision and accuracy be required. The yellow 

 colour is altogether wanting in the body, and there are only faint 

 traces of it on the shield-edges. The slime is very pale yellowish. 

 The characteristic blue tint of the tentacles leaves no doubt of 

 the species. — Wm. Denison Roebuck, Leeds, May 8th, 1885. 



Zonites nitidulus var. Helmii in S. Tipperary. — 



Mr. Rimmer has kindly sent me a specimen of this variety 

 amongst a number of other species collected the latter part of 

 June at Grantstown near Tipperary. In connection with its 

 occurrence in Ireland I may remark that Mr. Lionel E. Adams, 

 who has so thoroughly explored the neighbourhood of Coleraine 

 in County Derry, informs me that white varieties are very 

 prevalent in that district, though he does not enumerate this 

 particular variety in the list he has kindly furnished me with. —
