Show 1900.] FROM SINGAPORE AND MALACCA. 767 Hab. Singapore: 12 fms., rough bottom; south of Blakang Mati island. One male. I quite concur with Mr. Alcock in the separation of this species from the next, and its identification with Herbst's form. This specimen lacks the red colouring of his Indian examples, being only of a rather dark, yellow-brown hue. Dim. 9-5x7-75. 111. NURSIA HARDWICKII Leach. Nursia hardwickii, Leach, Zool. Misc. iii. p. 20 (1817) ; M.-Edw. Hist. Nat. Crust, t. ii. p. 137 (1837). Nursia plicata, Bell, Trans. Linn. Soc. vol. xxi. p. 307, pi. xxxiv. f. 4 (1855). Nursia plicata ?, Miers, Trans. Linn.

Singapore: 6-10 fms., rough bottom; from both north and south side of Blakang Mati island. A male and a female. Rather yellow than, like Mr. Alcock's examples, flesh-coloured. It is interesting to find this species living together with the closely-related N. plicata. Dim. d 10-5x9-5. $9-75x8-75. LXIII. Genus OREOPHORUS Riipp. 112. OREOPHORUS RUGOSUS Stimpson.

Crust, p. 130 (1882). Hab. Singapore: a male from 2-3 fms., muddy bottom, and a female from the reef. Dim. d 13x9. $ 18-5x14. LXIV. Genus FAVUS \ gen. nov. Carapace twice as broad as long, extended laterally so as quite to conceal the 2nd, 3rd, and 4th pairs of legs in flexion, but suddenly narrowed behind so as to leave the whole of the posterior pair exposed; front small and upturned ; antennules obliquely folded; antennas with flagellum either very rudimentary or completely absent, and basal portion imbedded in the inner orbital angle and fused with the orbital margin; orbits, in consequence, Favus=& honeycomb. |
