One valve of the bivalved shell, seen from the inside, of the rarer polyhedral form, which may be distinguished as a different species (Cœloplegma tritonis, compare p. 1758). h, hemispherical inner valve; g, galea; s, its base. |
Fig. 3. Cœloplegma murrayanum, n. sp., |
× |

h, The two hemispherical inner valves of the shell, seen from the right side; n, the central nucleus inside the central capsule; d, the astropyle; g, the galea; t, the nasal tube, arising from its base; m, its mouth; p, the phæodium, which is partly thrown out by the nasal openings, filling up the galea and nasal tube. |

g, The galea; t, rhinocanna of one inner valve; m, its mouth; p, phæodella filling up both the galea and the mouth of the rhinocanna. g1-g5, the styles arising from the galea; s, sieve-plate, which separates the cavity of the galea from the hemispherical valve (h). View in profile. |
