D 4; A 4; P 12-13.
Attains 10 cm. In our area, known only from a 7 cm specimen, washed up on the beach at Isipingo, Natal. May be the
same as Halieutaea coccinea Alcock , 1889, from the Bay of
Bengal, which is similar in squamation and markings.

Ids. About 8 species, 1 in our area.

7, Figs. 2, 2a 2b (Bay of Bengal).
D 6; A 4; P 14-16. Body not strongly dorsoventrally flattened , the head
nearly cube-like.
Colour in preservative: totally pale except for black tips
on tiny V and black peritoneum. Attains nearly 8 cm. South
Africa to the Philippines in depths of 500 m or more; 1 specimen (in poor condition, identification tentative) has been
collected in 910 m off Durban.
104.5 Halieutopsis micropus: 7 em SL (off Durban).

Disc markedly triangular. South Africa to Hawaii; about
6 species (this genus is currently being revised by J. H.
