GENERAL NOTES. 



A New British Vitrea — In the last (April) number of the 

 Journal of Conchology, Mr. B. B. Woodward describes a new Vitrea 

 from Cheshire, v. rogersi. It stands near v. alliaria and v. helvetica, 

 and has been identified also as v. glabra. It is named for the late 

 Mr. T. Rogers of Manchester, who first (1870) found British speci- 

 mens. 



Errata. — Owing to the absence of both editors from Philadelphia 

 during the printing of the April number, some typographical errors 

 escaped correction on the proofs. On p. 136, 4th line, the first word 

 should be Hieizan. In the second paragraph on p. 137, the second 

 word should be largillierti, and the 16th line from bottom of same 

 page should begin with a capital M. On p. 139 the term Pelecypods 

 is misspelled. There are also some other like errors.
