...…therefore added sparingly to the retinal matrix, and they remain rare: they constitute only a few per cent of all cones in every primate species where cones have been identified directly by microspectrophotometry (e.g. Bowmaker et al. 1987; Harosi, 1982; Dartnall et al. 1983; Mollon et al. 1984)....

...In a double-blind study that combined behavioural testing and microspectrophotometry (Mollon et al. 1984; Bowmaker et al. 1987), six phenotypes were identified in the squirrel monkey (Saimiri sciureus): all males and some females were dichromats, combining a short-wave pigment with one of three…...

...These studies ( Jacobs et al. 1981; Mollon et al. 1984; Bowmaker et al. 1987) found an S cone pigment in the population with a peak sensitivity at around 433 nm, and three di¡erent M or L cone pigments with peak sensitivities at 536, 550 and 564 nm. Monkeys diagnosed behaviourally as dichromats…...

...An explanation for the polymorphic colour vision of the squirrel monkey was given by Mollon et al. (1984), who suggested that there is a single X-chromosome locus for an M or L cone pigment Phil....

...The polymorphism of platyrrhine monkeys might then be maintained by frequency-dependent advantage (Clarke 1979; Mollon et al. 1984): the advantage of the individual dichromat in certain foraging tasks over trichromatic conspeci¢cs....

...It is therefore possible that the most successful groups contain a variety of di¡erent dichromatic and trichromatic individuals, each with advantages and disadvantages at particular foraging tasks, and that the maintenance of polymorphic colour vision in platyrrhine monkeys is by kin selection, giving a net group bene¢t for the detection of resources (Mollon et al. 1984)....

...In platyrrhine species with polymorphic colour vision, the variation among dichromatic males may simply be maintained by heterozygous advantage (Mollon et al. 1984): the advantage of trichromatic females at detecting fruits and conspeci¢cs against a background of foliage....

...The absorbance spectra of individual photoreceptors were measured with a modified dual-beam Liebman microspectrophotometer under computer control (Liebman & Entine, 1964; Knowles & Dartnall, 1977; Mollon et al., 1984; Bowmaker et al., 1991a)....
