Eye oval. Antenna without inner spine on basis; with outer basal seta on scale. Palp of maxillule and maxilla of three segments. Maxillipede i with outer seta on segment i. Chelae not fully developed. Leg 5 with small exopod. Epipods absent. Three pairs of pleopods. As the three specimens are all young it is possible that the pleopod on somite 2 may appear late. If this is so they may be referable to species D. X. Thalassinid VI (Fig. 24) Barrier Reef St. 44. Rostrum i-o mm.; body 37 mm. Rostrum broad, scarcely longer than antennule. Carapace with small, close-set teeth. Abdomen: somite 2 with large hollowed spine; somites 3-5 with low smooth ridge and small posterior point. Pleura all rounded. Fig. 24. Thalassinid VI. a. Side view. b. Telson. Telson three times as long as wide; lateral spines widely spaced; posterior margin convex, with four spines on either side of the median spine; spine formula 8, 1,8. Eye pale, slightly pointed. Antenna: basis with small inner spine; scale without outer basal seta. Palp of maxillule and maxillae of three segments. Maxillipede i with outer seta on segment i. Legs I and 2 with large chelae. Leg 5 without exopod. Epipods absent. Three pairs of pleopods. Stage L Total length 2-35 mm. Rostrum cylindrical with terminal spicules. Telson as in Callianassa, triangular, with median spine shorter than spine 7.
