There should certainly be a specimen of the 

 Hermit Crab in a Whelk-shell; and the Cleanser

 species, Geniaster eqtiestres; just above, to the

 to the right, Asteria gibhosa ; and immediately 

 above the Crihella^ the thin, leathery species, the 

 bird's foot Sea-Star, Falmipes memhranaceus. All 

 these species are small, easily managed, and especially

 their thousand sucker-like feet, in a very interesting
