A poem titled for one of these creatures describes “her perishable souvenir (10[1])of hope” and compares “close-laid Ionic chiton (“KYE-ton”)-folds” to “lines in the mane of a Parthenon horse.” One of these creatures titles a poem that begins with the questions “For authorities whose hopes are shaped by mercenaries? Writers entrapped by teatime fame and by commuters’ comforts?” and was written (10[1])by Marianne Moore. (10[1])A poem (-5[1])originally published in The Atlantic Monthly describes (-5[1])one of these creatures as a “frail tenant” who “stretched in his last-found home, and knew the old (-5[1])no more.” In that poem, this creature resides “where the Siren (-5[1])sings” and “Where (-5[1])the cold sea-maids (-5[1])rise (-5[1])to sun (-5[1])their (-5[1])streaming hair.” That poem titled for one of these creatures describes its “webs of living gauze” (-5[1])as a “ship of pearl” (10[1])and states, “Build (10[1])thee (10[1])more (10[2])stately (10[1])mansions.” (10[1])For 10 points, name this sea (10[1])creature that titles an Oliver Wendell Holmes (10[3])Sr. poem in which it is “chambered.” (10[2])■END■ (10[5])
