O^ecklace-shells and Winkles 227 



The shell is about three-quarters of an inch in length 

 and one-third in breadth. It is quite abundant on 

 the weeds at low-water mark and below, on all our 

 shores. 



The Globular Chink-shell {L. piiteolus) is rather 

 solid, glossj^ and opaque, the whorls not rounded but 

 rather angular in the centre (periphery); 

 yellowish white, with or without three 

 reddish bands, sometimes uniformly dull 

 reddish brown. Spire scarcely raised 

 above the body whorl, which includes 

 four-fifths of the entire bulk of the 3 

 or 4 whorls. Mouth expanded, with a somewhat 

 angular base ; fissure wide and deep. It may be 

 found in numbers feeding on small weeds, such as 

 Carrageen (CJiondrus crispiis), 

 about low - water mark. The 

 Pallid, Chink-shell {L. p>Midula) 

 is almost triangular, greatly ex- 

 panded in front, thin but opaque, 

 glossy, of a j^ellow-green colour : 

 epidermis somewhat thick ; 

 mouth very large. The fissure 

 in this species is exceedindy ^sg^ ^"^ y°^"g °f p^h^^ 



-l ^ ■^ Chink-shell 



large and funnel-shaped, exposing 

 nearly all the hollow spire. Although widely dis- 

 tributed along our shores, this species is found chiefly 

 on the south and west, at low water and for a few 

 fathoms below it. The eggs are deposited in oval 

 patches on seaweeds, as shown in our figure, where 

 also are depicted some aspects of the fry.
