Description
Oral side flat, aborally hemispherical to highly conical, apical system ethmophract, peristome slightly elongate along III-5 axis, gill slits rudimentary, auricles low, periproct ovate, inframarginal, larger than peristome, 4 genital plates, perforate, interambulacral tubercles numerous, in diagonal pattern adradially and interradially to central tubercle. [Contrary to the opinions of LAMBERT (1911), HAWKINS (1919), and MORTENSEN (1948), Pyrina petrocoriensis DES· MOULINS, 1837, cannot be the type of Pyrina D£SMOULINS, 1835, as it was not included in the original list of species assigned to the genus. COOKE'S 1946 designation of Nucleolites castanea BRONGNIART, 1822, one of the species origin~ ally referred to the genus, makes Pyrina DESMOULlNS, 1835, (non auctorum) a subjective synonym of Conulus LESKE, inasmuch as N. castanea has long been accepted as a typical member of Conttlus.]
