Penaeopsis Lysianassa (de Man). Penaeus Lysianassa J. Gr. de Man, in: Journal Linnean Soc. London, Zoology, XXII, 1888, p. 290, PI. 19, figs. 1—11. 1 young male collected 1892 by Mr. Herbst at Bagan Api Api, Sumatra. 2 young males and 2 young females collected October 1911 by Dr. P. Buitendijk in the road of Samarang. The specimens were compared by me with three full-grown cotypes from the Mergui Archipelago, 2 males and 1 female, preserved in my private collection. The examination revealed the remarkable fact, still unknown, that, like in Penaeopsis spinulicauda Stebb. from Durban Bay, the lateral margins of the telson are armed with numerous little spines up to a short distance from the acuminate tip; they seem to be 20—25 in number in the adult species, on the posterior half of the telson, and to increase in length from before backward, the posterior being 1/4 to 1/3 mm. long.
