This is a local and rare species, having been recorded 
for N. E. Yorks., Ayr, Linlithgow, Swansea, Cork, and 
Jersey. It is always found near the sea-coast. Owing to 
its rarity its appearance is little known, and in museums 
and collections the label is often prefixed to young speci- 
mens of S. cedegans, etc. I have mistaken a dwarf Z. 
peregra for it, and others have done the same. It is, 
however, very distinct from the rest of the genus, being 
very much smaller, with a longer spire in proportion to its 
size, having very convex whorls and a correspondingly 
deep suture. I would advise any fortunate finder to have 
a specimen authoritatively identified before placing it per- 
manently labelled in his collection. 
Sub-order.—PULMONOBRANCHIATA.
