(with two text-figures) ABSTRACT.– A collection of 35 Mabuya cumingi from one locality on Luzon, Philippines, provides additional data on the species' morphology and biology. The parietal eye spot is variable and not correlated with either snout-vent length or sex. There is a significant correlation between the number of keels on the dorsal scales and the snout-vent length and between the head length and the number of maxillary teeth. There is a pronounced sexual dichromatism: males have prominent ventrolateral orange stripes which females lack. The species is oviparous. Females with large follicles or ovarian eggs range 40-45 mm (mean = 43.1 mm) in snout-vent length, have 2-3 eggs (mean 2.2) and were collected in a period coinciding with the end of the rainy season. In both sexes, snout-vent length is in slight positive allometry with head length. There is no significant difference between the sexes in either snout-vent length or the number of paravertebral scales. The presence or absence of pigment in the parietal peritoneum is variable in Mabuya and is likely to prove to be an important phylogenetic and/or ecological character.

Statistical tests are identified in the text. The level of significance was 0.05. Polarity of character states was made by ref- erence to the Pariocela subgroup of Eumeces (see Greer et al., 2004, for rationale). We do not adopt the recent taxonomic sub- division of the genus Mabuya (Mausfeld et al., FIGURE 1: Mabuya cumingi (UF 135131). Photo.
