enjoy very much. When first found there was about half a 

 millimetre of new shell formed. By the end of the first week, 

 thereafter, the new addition measured three millimetres ; by the 

 end of the second week 6-25 millimetres; by the end of the 

 third week 11-5 millimetres, and by the 17th of May the 

 mollusc had begun to form a Up, very Uttle being thereafter 

 added to the length of the new shell, for at the end of the 

 fourth week, by which time the lip was well formed, the total 

 growth measured 12*5 millimeters, so that only one millimeter 

 of an addition had been made during that week. The new 

 shell was much darker in colour than the rest, but was similar 

 in the absence of any band ; the specimen thus formed a sort 

 of link, joining v. flavescens with v. marmorata. Possibly the 

 difference in colour might be due to difference in the kind of 

 food it had lived on. As long as the new growth was proceed- 

 ing vigorously the mollusc fed greedily, but after the lip was 

 fairly well formed this avidity for food ceased, and it would fix 

 itself to some part about the window, and remain quiescent for 

 a considerable period, ere showing an inclination to feed. 



I had begun to anticipate the securing of an interesting 

 addition to my collection in this parti-coloured Helix, when one 

 day it was found on the floor crushed to pieces. One might 

 introduce an "if" here, but after the accident has happened 

 the " if" may as well be left out. I find that " ifs " generally 

 lead to either needless recriminations or regret, and are not 

 philosophic. 



Obituary. — Thomas Glover. 



Amongst the few men in Manchester, who took an interest 

 in Conchology from the early part of the present century, must 

 be mentioned the name of Mr. Thomas Glover, who died in 

 August last at Southport, aged 92 years, having been born in 

 Blackburn, in May, 1795. His father and mother died whilst 

 he was yet a young man. When quite a little boy he evinced 

 a great delight in collecting plants, shells, and insects, and the
