BYNE : MARINE MOLLUSCA OF TEIGNMOUTH. 185 



O. lactea L. Dwarf-sized forms dredged alive and dead in 

 mud. They are fairly common, but only one large shell 

 has occurred alive. 



O. pusilla Phil. Dredged alive and dead with O. lactea in 

 mud, but, like the latter, they also are mostly dwarfed. 



O. acicula Phil. One dead example trawled. ' 



Eulima polita L. Trawled alive in the bay, but not adult. 



E. distorta Des. Trawled alive. 



E. bilineata Aid. Adult shells trawled alive in the bay. 



Natica catena DaC. Trawled occasionally, and cast up 

 alive and dead on sandy ground. 



N. alderi Forb. Fresh examples trawled. 



Adeorbis subcarinatus Mont. In the J. C, vol. vi., 

 p. 164, I recorded the occurrence here of this species 

 alive on the 28th July, 1888, when ten specimens were 

 obtained from one rock. In the fall of that year, some 

 twenty more live examples were taken from another rock. 

 It does not appear that this species had been previously 

 found alive on the English coasts. A few dead specimens 

 have been found in drift, and also dredged. 



Lamellaria perspicua L. A magnificent lot of this species, 

 adult and alive, were stranded in this neighbourhood, 

 together with live young B. hydatis, fine F. aperia, Sind 

 young Lidraria elliptica. Trawled alive. They have fre- 

 quently occurred dead on the beach. 



Velutina laevigata Penn. Fine adult and young specimens 

 occasionally trawled alive on rough ground ; dead ex- 

 amples on the beach. 



Aporrhais pes-pelicani L. Obtained chiefly by oyster- 

 dredging, some remarkably fine. Four specimens with 

 four spurs each have occurred. 

 Cerithium reticulatum DaC. Three specimens trawled 



alive, and one from drift. 

 C. perversum L. Three live examples amongst some C. 

 tubercularis: also occurs alive at lowest water mark.
