«P. testa delicata, mediocri, tenui, inaequilaterali, aequivalvi, planato-convexiuscula, variis coloribus ornata, nunc flavida, nunc pallide violacea, interdum rufescente, vel alba, interdum pulchre maculata, auriculis valde inaequalibus, posticis radiantibus, radiis arcte squamatis, anticis tenui-costatis, aeque squamatis, valva sinistra costis ad 22, laevibus, in statu juvenili pulcherrime squamatis, deinde laevissimis, paullum irregularibus, interstitiis 5-seriatim arctissime scobinatis, asperulatis, valva dextra costis arctis ad 50, interstitiis interdum planatis, interdum una serie squamarum scobinata decorata, umbonibus acutis, sublaevibus, pagina interna radiatim sulculosa.

A very delicate Pecten, variously coloured, in which the ribs and interstices of the left valve, especially, exhibit much elaboration of sculpture. When young, round, shining, very fugitive scales exist, especially towards the ventral margin, whilst the interstices are closely scobinate, there being four or five closely imbricate rows of minute squamse. The right valve is by no means so elaborate, while the radiating ribs, irregularly placed, are more than double in number, not, indeed, leaving much space for interstitial development. Doubtless allied to P. limatula, Reeve,* and others of that section, the right valve, indeed, is hardly separable in sculpture from that of limatula; but its fellow is more elaborately sculptured with close rows of interstitial scales than is the case in that species, which is reported from Nightingale Island, Tristan d'Acunha (Rep. "Challenger" Exped., xiii., p. 297, pl. xxi., figs. 5, 5a).» * Reeve, Conch. Icon., viii., pl. xxviii., fig. 124.

«Talochlamys humilis shares closer sculptural similarity with T. pulleineana (Tate, 1887) from southern and eastern Australia than with its only two Atlantic congeners, T. multistriata of the Eastern Atlantic and South Africa, and T. multicolor (Melvill & Standen, 1907) from Gough Island, and is thus more likely to be a sister species of T. pulleineana.»
