EULIMA. 203 



A closely allied species, from Puget Sound, has been 

 described by Dr. P, Carpenter, in the ^ Proceedings of 

 the Academy of Natural Sciences of Philadelphia '' for 

 1865, as E. mica/is ; respecting which he observes, " An 

 E. politce varietas Pacifica ? ^^ 



This would be a beautiful object for the aquarium, 

 with its pencilled tentacles, golden markings, and its 

 bright eyes peering through the porcelain shell, Avliich 

 slowly trails along the ground. The spire is seldom 

 perfect : the top whorls, being useless, are broken off ; 

 and the truncated portion is covered by a shelly plate, 

 formed by the hindmost lobe of the mantle. I have a 

 specimen containing the animal, but having only three 

 whorls left. Sometimes the shell exhibits several varices, 

 caused by a repetition of the outer lip at successive 

 periods of growth. My largest example is more than 

 an inch long and of proportionate breadth. 



It appears to be the Turbo Icevis of Pennant, and is 

 the Strombiformis albus of Da Costa, Rissoa Boscii of 

 Payraudeau, E. elegantissima (and perhaps also E. gla- 

 berrima) of Risso, Melania Gervillii of CoUard des 

 Cherres, and E. anglica of G. B. Sowerby. 



2. E. interme'dia"^, Cantraine. 



E. interimdia, Cantr. Mai. Med. (Suppl.) p. 14. 



Body milk-white : mantle rather thin ; edges even with the 

 mouth of the shell: tentacles C5'lindrical, rather short and 

 diverging, with blunt tips : eyes small and black, placed close 

 together on short bulbs ; they are always conspicuous (and 

 open; do mollusks ever sleep?) ; each is encircled by a dark- 

 orange disk : foot shortish, slightly cloven in front, and bluntly 

 pointed behind, expanded towards tlie sides. 



Shell smaller than E. polita, having a narrower base, and 

 consequently more spindle-shaped ; it is not quite so solid, 



* Intermediate, i. e. between E. polita and E. distorta.
