1. UTICA GEACILIPES, White. (PI. XIII. Fig. 6.) 



Bronte lata, anteriore margine valde recto, post-frontem ad medium thoracem pertinente, eminentia. 

 magna lata subtriangulari, a transversa carina separata per altam lunatam depressionem, linea subimpressa 

 a finibus ad latus carinas porrecta. Pedibus gracillimis, pilis fimbriatis. 



Hab. Insulas Phiiippinas. 



Utica gracilipes, White, Pro. Zool. Soc, May, 1847. 



Front wide, fore-edge very straight ; behind it and extending to the middle of the 

 carapace, a considerable, wide, somewhat three-sided elevation, separated from the trans- 

 verse ridge by a deep lunated depression, from the ends of which a slight impressed line pro- 

 ceeds to the side of the ridge, where it deepens. 



Hind-legs very slender, and fringed with hair. 



Hab. Philippine Islands. 



Mr. Cuming found this species in a fresh-water rivulet among the mountains of the 

 Island of Negros. It was also obtained during the Expedition of the Samarang in the Island 

 of Mindanao, in the deep still muddy fresh-water rivulets near Samboangan, hiding under 

 weeds and rotten wood. When caught, it feigns death, contracting its limbs and rendering 

 them perfectly rigid. Its colour, when alive, is dark-red brown, on the under-surface dark 

 chocolate-brown, lighter on the legs and abdomen, which latter in the female has a yellowish 

 line down the middle. 



ix. leucosim:. 



Besides several species of Leucosia new to science, a few Philyrce were obtained in 

 the Sooloo Sea, and on the coast of Borneo from a rocky stony bottom ; among them 

 was the P. scabriuscula of Leach, which, when alive, is of a chocolate colour, with red-brown 

 legs ; the Philyra latifrons (A. & W.), which is of a deep red brown, with orange fore- 

 legs ; and another with a dead-white pohshed carapace, marked with dark olive brown, and 

 the fore-legs banded with the same. The Philyrce have much the same habits as the 

 Leucosice, being slow-moving, torpid Crustaceans, never using their fore-legs for defence, and 

 living in deep water on a clean rocky or stony floor. A pretty species of Myra was dredged 

 in the Sooloo Sea of a delicate flesh colour, with two blood-red spots on the carapace. 

 The Myrafuyax, which is punctulated and dark liver-coloured on the carapace, and a new 

 species with white carapace and pinkish legs, were also procured ; they are found usually in 

 about eight or ten fathoms on a muddy bottom ; one species is common in the mud of 

 Manda bay. The Arcanice are usually of a dead-white colour, variously marked with red, 

 with the legs spotted or banded ; they prefer deep water and a clear gravelly bottom ; several 

 were dredged on the coast of Borneo in twenty-four fathoms. The Iocce inhabit very deep 

 water, and are inert and feeble ; when taken they contract their legs and remain perfectly im- 

 movable. The Iphides are usually found concealed in madrepores and sponges, and live in a 

 coral bottom in from fifteen to twenty fathoms ; they are numerous on the coast of China,
