Tetrathyrus forcipatus Claus, 1879. Barnard, 1930. Shoemaker, 1945. A. Hyperiidea Gammaroidea Tribe Derivata, Wolt. Family Scinidae Stebbing, 1888: 1270. Stephensen, 1918: 16. Wagler, 1926: 324. Pirlot, 1929: 53. “Head deeper than long; eyes small and separated. Pleon narrower than peraeon, 5th and 6th segments fused, telson short. Superior antennae strong, erect, not very flexible, fixed at an angle to the head. Inferior antennae fixed below and behind the superior antennae, variable with age and sex. Mandibles without palp. Maxillae well developed. Gnathopods simple and slender. Third peraeopod generally the strongest, fifth the shortest; dactylos sharp, not retractile. Inner rami of uropods generally fused with the peduncles.” (Translated from Pirlot.) Only one genus, Scina, has been recorded from New Zealand waters. Three species were taken by the “Terra Nova”. Genus Scina Prestandrea, 1833. Prestandrea, 1833: 10. Stephensen, 1918: 19. Wagler, 1926: 324 (Key to Species). Pirlot, 1929: 62 (Key to Species). “Head anteriorly truncated. Superior antennae very robust, their bases occupying almost all the anterior face of the head. Maxillae with inner plates divided. Gnathopods slender, simple. Third pair of peraeopods generally the strongest. Inner rami of the uropods fused with the peduncles which are long but not smooth.” (Translated from Pirlot.)
