Twelve specimens standard length 16·8–53·0 mm, including 2 post‐larvae (hitherto unknown to the genus), of Argyripnus atlanticus Maul 1952 are reported. The external characteristics of adults are summarized and the internal features of 2 specimens described. A swimbladder is present. The post‐larvae are described and their distinction from other maurolicid genera given. Development of the species is considered in terms of morphometric growth changes and increase with age of photophore number. A relatively longer tail and shorter preventral length is characteristic of juveniles and post‐larvae, but other body proportions remain approximately constant at all growth stages. A full complement of photophores is attained at approximately 43 mm standard length. Morphological examination of the ovaries of 7 females indicate that first full maturation has not been reached. Development, geographic variation and habits of the species are discussed.
