“…Most platyctenids are small, usually less than 3 cm in the longest dimension. Many are commensal in a specific situation such as among colonies of bryozoans, anthozoans, hydroids, tunicates, and the spines of echinoids (Gordon 1969;Matthews and Townsley 1964 ;Rankin 1956). Although the systematics of the seven genera in the order is In this paper, we describe a new species of a platyctenean ctenophore collected in McMurdo Sound, Antarctica, during the austral springs of 1967 and 1968.…”

1972. A new species of platyctenean ctenophore, Lyrocleis flavopallidus sp. nov., from McMurdo Sound, Antarctica. Can. J. Zool. 50: 47-52. Lyrocteis flavopallidus sp. nov., a large (up to 110 mm tall) platyctenean ctenophore from the Antarctic, is described on the basis of the external morphology. The pale straw-yellow color, lack of ridges and frills on the body and arms, presence of small papillae on the body, and geographical location are considered sufficient to distinguish L. jTavopallidus from L. imperatoris Komai, 1941, the only other species in the genus. The systematic placement of L. flavopallidus is somewhat uncertain because neither the anatomy of the reproductive system nor the larval development is known; the species may represent a new genus and possibly a new family.Lyrocteis jlavopallidus is sedentary and usually found atop spongesor other elevated surfaces. However, it is able to move at least 1 to 2 m per day possibly to attain a more advantageous feeding position. Food items are captured by the sticky tentacles and transferred to the mouth.

On dkrit ici la morphologie externe de Lyrocteisflavopallidus sp. nov., ctknophore platycttnide de grande taille Uusqu'A 110 mm) de l'htarctique. La coloration jaunltre, l'absence d'&tes et de franges sur le corps et les bras, la prksence de papilles minuscules sur le corps et entin la situation gtographique de cet animal en font une espke distincte de L. imperatoris Komai, 1941, seule autre espkce du genre. La position systtmatique de L. jTavopallidus demeure incertaine car I'anatomie de son systeme reproducteur de meme que son dkveloppement larvaire sont encore inconnus; peut-&re s'agit-il d'un autre genre ou meme d'une autre famille.Lyrocteis flavopallidus est un animal skdentaire se rencontrant ordinairement sur des tponges ou sur toute autre surface surklev&. I1 peut cependant ramper d'au moins 1-2 m par jour, probablement pour atteindre une meilleure source de noumture. Des tentacules visqueux lui servent A attraper des particules de nourriture qu'il porte ensuite I sa bouche. , ~ --Medd. Naturhist. &en. Kjobenhavn, 17: 249-253. -1912. Ctenophora.
