Band of transverse dermal folds on ventral surface of head broadly rounded with apex about three quarters of horizontal prenasal length behind symphysis of lower jaw, extending from below lower edges of first four gill slits on either side; up to about 20 folds present.

Spiracle moderately large, semicircular; located dorsolaterally on head, entirely visible in dorsal view; lower margin above level of upper eye, slightly more than its diameter away from eye; no lobe-like fold on posterior margin; greatest diameter 3.48 (2.84–4.28; 2.80–3.81) in eye length. Gill slits directed slightly anteroventrally from top to bottom; relatively equal in size, becoming progressively longer from first to fifth; fifth longest, its height 3.1 (2.5–3.0; 2.6–3.0)% TL.

Teeth strongly differentiated in upper and lower jaws, with upper teeth much smaller than lower teeth. Upper teeth of adults (based on MNHN AB-248, AB- 249 and AB-250) moderately large, with erect cusps, becoming slightly oblique posteriorly towards mouth corners, bases slightly overlapping ( Fig. 8a View FIGURE 8 ).

(<524 mm TL) (> 644 mm TL) Colour. In preservative: Dorsal and lateral surfaces medium brownish to greyish brown; ventral surfaces slightly paler; waterline between dorsal and ventral colour shades very diffuse on lower sides. Fins without distinct markings in preserved specimens examined (no fresh material observed); dorsal fins and ventral caudal lobe of near-term embryo blackish distally, with upper caudal lobe with a broad whitish margin with a dusky marking anteriorly.

Size. Type specimens ranged in size from 317 to 950 mm TL. The smallest free-swimming individual was 408 mm TL; a late-term embryo of 317 mm TL still possessed a small external yolk sac; Cadenat (1960) recorded an embryo of 395 mm TL from a pregnant female. A female of 863 mm TL was mature and pregnant. Cadenat (1960) reported adult males between 715 and 765 mm TL and adult females between 890 and 990 mm TL.

Distribution. Type specimens were from the Mozambique Channel ( Madagascar and Mozambique), and off Senegal, Côte d’Ivoire, Equatorial Guinea, and Togo at depths of 340– 500 m. The BMNH and ZMB specimens were most likely collected by Anchieta from Angola or Mozambique in the 1800’s. Additional specimens examined by Munoz-Chapuli & Ramos (1989) were recorded as being collected from Morocco, the Canary Islands, and Ghana at depths of 370– 610 m.

Etymology. Named after Dr Robin Leslie (Fisheries Branch, Department of Agriculture, Forestry and Fisheries in South Africa) who has contributed greatly to our knowledge of southern African chondrichthyans and provided numerous important specimens and tissue samples for various projects.
