. Disc low, flat above and below, outline pentagonal, interradii slightly rounded. Dorsal surface of disc covered with very numerous small, irregularlyshaped scales, with larger, rounded centrodorsal present, as are similar radial plates, at about 1/2 distance to margin; disc plates become larger towards margin in both radii and interradii. Radial shields almost 2.5 times longer than wide, widest distally, divergent, strongly curved, sharply pointed proximally, extend inwards for about 1/2 disc radius. Radial shields separated proximally by several rows of scales, at distal end by a single larger scale. Ventral surface of disc with numerous small scales. Genital slits long, extending from about middle of oral shield to outer ends of radial shields; genital scales very narrow proximally, but widen near margin on ventral surface; at proximal end, adjacent to oral shield, cleft lacks papillae, beyond on adradial edge are small, low, almost confluent papillae, becoming larger distally, and arm comb comprises short, slightly flattened, blunttipped spines; on abradial side a second dorsal arm comb is developed on side of arm, with much shorter, thinner spines, usually visible but sometimes concealed. Oral shields relatively large, about as wide as long, pointed proximally, slightly constricted at start of genital cleft, widest at the straight distal margin. Adoral shields meet within, extend distally to first lateral armplate, and abutting proximal end of genital cleft. Oral plates with 5 oral papillae along oral slit, not extending beyond second oral tentaclepore; outer 3 papillae blunttipped, subrectangular, inner 2 more pointed; a single, slightly larger pointed apical papilla at jaw apex, sometimes absent; teeth pointed, in a single vertical series. Second oral tentaclepore conspicuous, opening outside oral slit, proximal or adradial margin with 6–7 flat papillae, more or less aligned with oral papillae, distal or abradial margin with 4–5 similar papillae.

Dorsal armplates in contact throughout remaining arms; at base, between radial shields are 2–3 small rectangular plates, usually with spinelets of inner arm comb apparent; next 3–4 plates are wider than long, more or less subrectangular; more distal plates are longer than wide, with straight proximal and lateral margins, distal margin slightly rounded and the widest part of plate. Lateral armplates with 2 very slender, delicate armspines, up to about 1/2 length of arm segment; upper spine placed about midway up side of arm, lower close to tentaclepore. First 2 ventral armplates just in contact, remainder separated; first is a broad plate, with a very slight median point on distal margin; second is slightly longer than wide, pointed proximally and subtriangular; the plates then become wider than long with small median points on proximal and distal margins, that on distal margin usually slightly thickened. Tentaclepores relatively large with numerous tentacle scales; proximal pores with 5–6 scales on proximal margin, outer scale spiniform, slightly spaced from lower armspine, others are small, flat and squarish; distal margin has 4–5 squarish papillae. On distal pores there are 3–4 scales on the proximal margin only, the inner bluntly pointed, the outer spiniform; tentaclescales are easily dislodged.</paragraph>
