JOURNAL OF CONCHOLOGY. 175- 



Specimens of all the above have been submitted for 

 inspection and verified for the Conchological Society by Mr. 

 J. W. Taylor. 



The general conclusion from the results of my walk seems 

 to be that the limestone district of central Ireland, while 

 offering a fairly good collecting ground, has no remarkable 

 variety of species. The Lough Erne series of lakes would, I 

 think, repay a thorough investigation ; but the only means of 

 doing this would be in a boat, as the shores are almost entirely 

 occupied by castles and demesnes, to the exclusion of the 

 pedestrian. 



Ed. Note. — It is difficult to express in type the double method in which the formulae of 

 Helix neinoralis, &c., are expressed by the author in his manuscript ; he shows the 

 fprmulae for each species both at the mouth and on the body of the shell. The 

 mouth-formula is here shown by parentheses ( ) enclosing bands coalesced ; if they 

 coalesce differently on the body of the shell it is shown by the coalesced bands 

 r being printed in dotted figures, thus ; (12345). 



Colorado Mollusca. — In November last year I found 

 Conulus fulvus, Hyalina arboiea and Patula cooperi^ near 

 Egeria, Routt Co., in the Bear River Division. Most of the 

 P. cooJ>en belong to a var. nov. minor (diam. 14 mill.), which 

 I have not seen elsewhere in Colorado, though Hemphill found 

 a small variety of this species in Utah. — -T. D. A. Cockerell, 

 West Cliff, Colorado, March 8th, 1889. 



Sinistral Helix nemoralis in Lancashire. — A nice 

 specimen of this monstrosity has been very kindly added to my 

 collection by Mr. F. C. Long, of Burnley. He took it on the 13th 

 of July last, near the 'Tim Bobbin' Inn, Burnley. It is an 

 immature libellula 12345, and though in quite fresh condition 

 was unfortunately dead when found, otherwise it might have 

 been fed to maturity. As being probably the first instance 

 noticed of the occurrence of this form in our county, the record 

 may not be without interest. — R, Standen. -
