Description:
Nematocarcinus tenuirostris Sp. Bate, var. sibogae n.\nStat. 300. January 30, 1900. 10\xc2\xb0 48\'.6 S., 123\xc2\xb0 23\'.1 E. 918 m.\nBottom fine grey mud. 4 adult females, 3 of which are laden with eggs.\nIn the typical Nemat. tenuirostris, as described by Spence Bate (Report Challenger Macrura) and Miss Rathbun (The Brachyura and Macrura of the Hawaiian Islands. Wash. 1906, p. 926, Pl. XXIII, fig. 6), the rostrum is from two-thirds to one-half as long as the rest of the carapace, projecting horizontally forwards, the upper margin is slightly convex and it bears 9\xe2\x80\x9413 dorsal and 1 or 2 ventral teeth. In the adult specimens, collected by the \xe2\x80\x9eSiboga" off the south coast of Rotti, the rostrum measures, however, somewhat more than two-thirds the length of the carapace proper and is more or less obliquely turned upward from the orbital margin to the tip; it is styliform, tapering, quite straight, not at all convex in front of the eyes and armed above with 8\xe2\x80\x9410 teeth, beneath with one and of the dorsal teeth 3 or 4 stand on the carapace, posterior to the orbital margin. Length 146 mm.\nPlesionika longipes A. M.-Edw., var. indica n.\nPandalus longipes, A. Milne-Edwards, Recueil de Figures de Crustac\xc3\xa9s nouveaux ou peu connus, Avril 1883, Pl. 20.\nStat. 254. December 10. 5\xc2\xb0 40\' S., 132\xc2\xb0 26\' E. Near the Kei-islands. 310 m. Bottom fine, grey mud. 1 male and 8 ova-bearing females.\nWhen the figures in the quoted \xe2\x80\x9eRecueil" are indeed correct and accurate, the specimens, collected by the \xe2\x80\x9eSiboga", differ from the typical species that occurs in the West Indies, by the somewhat shorter rostrum, which is less strongly upturned and armed both dorsally and ventrally
