81.8 Notolepis rissoi
(Bonaparte, 1840)
Paralepis risso Bonaparte, 1840: (338) 152, fasc. XIX, PI. 124, Fig. 2
(Mediterranean). Notolepis rissoi: Rofen, 1966: 280*; Post, 1968: 103.
D 9-10; A 28-33 ; P 11-13; LL 59-67; GR (8-9)+(30-33) forming bony
bases with 12 to 25 needle-like teeth. Depth 12.5- 16.5 ; head 3.7-4.5.
Anterior naris above rear tip of maxilla. Body scales easily shed.
Scattered large melanophores in dorsal colour band; distinct black spot at A origin. Attains 30 cm. Mesopelagic to
bathypelagic; worldwide in temperate and tropical waters.
81.8 Notolepis rissoi: 24 em SL (after Rolen , 1966).
Genus Paraiepis Cuvier, 1816
Six species, 1 may occur in our area.

Omosudis elongatus Brauer, 1906: 140, Fig. 68 (Gulf of Guinea); ?Gilchrist & von Bonde, 1924: 10; ?Smith, SFSA No. 186*; Post, 1972: 156.
Paralepis elongata: Maul, 1962: 539* ; Post , 1972: 156.
D 10-12; A 23-25 ; P 16; LL 63; GR (2-5)+(13-15). Depth 10, head 4.1.
Gill-plates with 5 or 6 teeth. Anterior nostril in front of rear tip of maxilla.
LL nearly reaches C base. Young stages « 40 mm SL) with 9-13
peritoneal pigment patches , the anterior 4 sections are very large and
separated by extremely narrow intervals.
Attains at least 21 cm. Gulf of Guinea and off west Africa.
(Data from Maul, 1962.) The specimen from Natal, listed
by Gilchrist & von Bonde (1924) , is lost; and the occurrence
of P. elongata in our area thus needs confirmation.
81.9 Paralepis elongata: 20 em (after Maul, 1962).
Genus Sfemonosudis Harry, 1951
Thirteen species; 3 in our area, known from postiarvae
and from young adolescents only ; morphometric data as
81 : PARALEPIDIDAE (BARRACUDINAS)
well as colour pattern may be considerably different in
adults.
