Plate XIII - Report on certain Hydroid, Alcyonarian, and Madreporarian Corals procured during the Voyage of H.M.S -ext5.png
Original description : Ovoid nematocyst, confined in position to the bases of the zooids and general superficial layer, not occurring in the tentacles, a) The cell expanded. b) The cell with the thread fully projected. The respective lengths of the various parts of the thread and cell are drawn exactly according to measurements. Structures occurring in Millepora nodosa.

Plate XIII - Report on certain Hydroid, Alcyonarian, and Madreporarian Corals procured during the Voyage of H.M.S -ext4.png
Original description: View of the surface of the ccEnosteum, magnified 80 diameters, showing one complete system of pores, composed of a central gastropore, and eight surrounding smaller dactylopores. Diameter of the central gastropore = 0.25 mm. Largest diameter of the whole group of pores = 1.5 mm. Structures occurring in Millepora nodosa.

Original description : Three-barbed nematocyst, of the form peculiar to Bydrozoa, occurring in the tentacles of the zooids and also sparingly on the general surface of the coral. a) The cell with its head protruded and thread partially projected. b) The cell in the unexpanded condition. The figures are drawn exactly to measurements.. Structures occurring in Millepora nodosa.

C. Gastropore in horizontal section. C', C'. Dactylopores. B'. Branch of a canal-system which communicates by means of a lateral offset with one of the dactylopore cavities. The dark linear bodies represented as embedded in the calcareous matter are cavities bored by parasitic vegetable organisms, the black dots being spore-cavities. In one of the dactylopores a branched mycelial thread is seen to cross over between the tubular cavities bored in the cnosteum.
