Monst. decollétum ( Jeff.). Spire truncate. 
3) P. JENKINSI Sw27z. Pl. VILL, f..13. 
Conical, tapering, rather solid, pale horn-colour ; finely striated in 
line of growth ; whorls 5—6 ; mouth ovate, angulated above, the entire 
rim standing out from the shell ; ofercz/um horny, concentric. A. 54 
mm. B. 3mm. 
This species was discovered by Mr. A. J. Jenkins at 
Plumstead in 1889, and submitted to Mr. E. A. Smith, 
who considered it a new species.* This however was not 
the first time this shell had been taken in England, for 
Mr. Sheriff Tye informs me that he has specimens—un- 
named—collected some years previously by the late Miss 
Fairbrass, near Deal. 
In 1891 I found it at Sandwich—perhaps in Miss 
Fairbrass’ locality,—and_ in 1892 Mr. Chas. Oldham and 
I found a numerous colony near Exeter. Circumstances 
then led me to hazard the conjecturef{ that the shell had 
been imported in Baltic timber, and I suggested that 
search should be made at Newhaven and Wisbeach, where 
Baltic timber is still ‘imported, and last year (1894), Mr. 
C. H. Morris of Lewes, found an exceedingly abundant 
colony near Newhaven. I have also taken it in the 
military canal at Hythe. It has also been found in con- 
siderable quantities in two places in a Staffordshire canal.
