FIGURE 1 in Description of Tottonophyes enigmatica gen. nov., sp. nov. (Hydrozoa, Siphonophora, Calycophorae), with a reappraisal of the function and homology of nectophoral canals
FIGURE 1. Schematic representations of canal systems of physonect nectophores, in lateral view. A. Halistemma sp. (based on Pugh & Baxter, 2014, Figure 14 in partim), B. Bargmannia elongata (based on Pugh, 1999b, Fig. 2C), C. Apolemia uvaria (based on Totton, 1965, Fig. 15). lrc. lateral radial canals; mca, mcd. ascending and descending mantle canal, respectively; mll, mlu. lower and upper parts of muscular attachment lamella, respectively; np. nectosomal palpons; nst. nectosomal stem; pce, pci. external and internal pedicular canal, respectively.

FIGURE 3 in Description of Tottonophyes enigmatica gen. nov., sp. nov. (Hydrozoa, Siphonophora, Calycophorae), with a reappraisal of the function and homology of nectophoral canals
FIGURE 3. Schematics showing the diversity in the arrangement of the various canals in the nectophores (Rosacea and Vogtia) or anterior nectophore (Chuniphyes and a diphyid), and the region of attachment of the muscular lamella (shaded). Annotations as for Figures 1 & 2; abs, "ascending branch of somatocyst". The three canals arising from the internal pedicular canal are, from top to bottom the upper, lateral and lower radial canals on the nectosac, except for the diphyid where the bottom canal is the ostial ring canal as the lower canal is virtual. It remains to be determined whether the disjunct or internal portion of the pedicular canal is always present in diphyomorphs. Modified and adapted from Mapstone (2009) Figures 5 & 6.
