FIGURE 5 in Neverita delessertiana (Récluz in Chenu, 1843): a naticid species (Gastropoda: Caenogastropoda) distinct from Neverita duplicata (Say, 1822) based on molecular data, morphological characters, and geographical distribution
FIGURE 5: A: Size ratios (height/width) of 181 specimens of Neverita duplicata and 97 specimens of Neverita delessertiana from Massachusetts to Honduras (for localities see Table 2). The ratios range from 0.63 to 1.13 for N. duplicata and from 0.74 to 1.01 for N. delessertiana. B: The averages of the size ratios are 0.85 ± 0.006 (SEM) for N. duplicata and 0.90 ± 0.005 (SEM) for N. delessertiana (P <0.0001, nonparametric twotailed ttest).
FIGURE 4 in Neverita delessertiana (Récluz in Chenu, 1843): a naticid species (Gastropoda: Caenogastropoda) distinct from Neverita duplicata (Say, 1822) based on molecular data, morphological characters, and geographical distribution
FIGURE 4: Typical shells of Neverita duplicata (AC), and Neverita delessertiana (DF). The umbilical areas are shown enlarged in C and F. The ridge (keel) within the umbilical channel (closed arrows in D and F) of N. delessertiana is present in all specimens investigated. Additionally, the shape of the umbilical callus often differs between the two species [open arrows in C and F]. The callus of N. delessertiana in most specimens is more triangular (F) while that of N. duplicata is more rounded (C).
