MOLLUSCOIDA. 47 



Lepralia ciliata, Pallas ; Busk, Catal. p. 73, pi. 74. f. 1 & 2, 

 pi. 77. f. 3, 4, 5. 



Occasionally on the under surface of stones near low-water 

 mark ; more frequently on stones and shells from the coralline 

 ground. 



Lepralia variolosa, Johnst. ; Busk, Catal. p. 75, pi. 74. 

 f. 3, 4, 5, pi. 75. 



On shells and stones from deep water ; not uncommon. 



Lepralia nitida, Fab. ; Busk, Catal. p. 76, pi. 76. f. 1. 

 Abundant both between tide-marks and in deep water, on 

 stones and shells. The spines are in general less developed 

 than in those from the Channel Islands. 



Lepralia annulata, Fab. ; Busk, Catal. p. 76, pi. 77. f. 1. 



Instead of being partial to the laminarian blades, as on the 

 west coast, this species is not uncommon on the under surface 

 of stones between tide-marks, generally in small patches ; 

 and also occurs on shells and stones from deep water. Some 

 dried specimens are of a pinkish colour. 



Lepralia Peachii, Johnst. ; Busk, Catal. p. 77, pi. 82. f. 4, 

 pi. 97. 



Common on stones near low-water mark, and on stones and 

 shells from deep water. 



Lepralia ventricosa, Hassall; Busk, Catal. p. 78, pi. 82. f. 5 & 6, 

 pi. 83. f. 5, pi. 91. f. 5 & 6. 



Not uncommon on stones and shells from deep water. 



Lepralia punctata, Hassall ; Busk, Catal. pi. 90. f. 5 & 6, 

 pi. 92. f. 4, pi. 96. f. 3. 



Everywhere abundant on the under surface of stones in 

 pools and elsewhere near low-water mark, and also on shells 

 and stones from deep water. 



Lepralia Malusii, Aud. ; Busk, Catal. p. 83, pi. 103. f. 1-4. 

 Not uncommon on shells and stones from deep water.
