Plate 127. Cœlographida.
Diam.
Fig. 1. Cœloplegma murrayanum, n. sp., × 40
One valve of the bivalved shell, seen from the inside, of the usual ovate form.
Fig. 2. Cœloplegma murrayanum, n. sp., × 40
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., × 40
The entire shell, seen from the base of the aboral pole (dorsal and ventral valve connected by delicate teeth, catching into one another).
Fig. 4. Cœloplegma murrayanum, n. sp., × 100
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.
Fig. 5. Cœloplegma murrayanum, n. sp., × 200
h, The two hemispherical inner valves of the shell and the enclosed central capsule, seen from the oral side; d, the radiate operculum of the astropyle, seen in the frontal fissure between the two valves; n, the nucleus; k, the crystals; g, galea; g1-g5, the styles arising from the galea; t, nasal tube; m, mouth of it.
Fig. 6. Cœloplegma murrayanum, n. sp., × 600
Oral part of a central capsule, in profile. o, Opening of the proboscis; d, radiate operculum of the astropyle, which gives rise to the proboscis; e, the outer, i, the inner membrane of the capsule; k, groups of crystals; n, nucleus.
Fig. 7. Cœloplegma murrayanum, n. sp., × 1000
Three single groups of crystals, taken from the central capsule.
Fig. 8. Cœloplegma murrayanum, n. sp., × 300
One inner valve of the shell, in profile. h, hemispherical valve; g, galea; g1-g5, the tubes arising from it; t, rhinocanna or nasal tube; m, its mouth; b, frenulum.
Fig. 9. Cœloplegma murrayanum, n. sp., × 400
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.
Fig. 10. Cœloplegma murrayanum, n. sp., × 300
An anchor-pencil of the outer shell.
Fig. 11. Cœloplegma murrayanum, n. sp., × 1000
A single anchor-thread of a pencil.
Fig. 12. Cœloplegma murrayanum, n. sp., × 300
Terminal branches of a style.
Fig. 13. <f>Cœloplegma murrayanum</f>, n. sp., × 1000
