CEUSTACEA FEOM KUTCH AND SIND. g 



decomposition the granules are replaced by equally smaU pits. The lobes of 

 the carapace are indistinct, only the semi-lunar depressions at the sides of the 

 urogastric region are traceable. 



The front edge has a thickened margin, with two median projecting tubercles 

 and two others at the inner angle of the orbit; the distance between these inner 

 tubercles very nearly or fuUy equals the length of one antero-lateral margin. 

 The orbits are nearly circular, deeply indented above, and with a swoUen margin ; 

 below somewhat flattened, and with a sub-median projecting tubercle. Each antero- 

 lateral margin has eight tubercles, of which the last one slightly exceeds the 

 others in size and is also more pointed ; the costal ridges are distract, and each 

 nearly one-third of the breadth of the carapace. 



The basilar joint of the antennae is very long, at its base scarcely higher 

 than at any other part of its length ; it terminates with a truncate edge in 

 the orbit. 



The basilar joint of the antennulse is, as usually, semilunar, with a flexuous 

 upper edge ; auditory tubercles somewhat smaller than the superseding portion of 

 the basilar joint of the antennse ; epistome almost linear, conspicuously depressed 

 in the middle, especially below the inter-antennulary prolongation ; endostome with 

 a sharp, almost continuous, lower edge, the lateral endostomic ridges rather close 

 together and somewhat curving outwards. Suture between the sub-hepatic and 

 pleural region simple throughout. 



The second endopodite joint of the outer maxUlipeds is not much longer than 

 broad, about the middle slightly depressed, but without any distinct groove ; the 

 third endopodite is somewhat broader than the last, a little less high externally, 

 and with an obtuse angle on the inner edge ; the fifth endopodite is a little longer 

 than the fourth, both are narrow. The second exopodite is about as long as the 

 second and third endopodite together, becoming somewhat narrowed towards above. 

 It would appear as if the comparative width of the outer maxillipeds was a little 

 smaller in the male than it is in the female. 



The chelEe are very strong, each equalling in length the greatest width of the 

 carapace. The fore-arm has externaUy three spines : two near the base, one above 

 the other, and one anteriorly. The right hand is scarcely longer, but consider- 

 ably higher and comparatively more compressed than the left, on which, however, 

 the fingers are thinner and longer : they are internaUy obtusely ridged, while the 

 fingers on the right hand are internally broadly flattened : there is sometimes at 

 the base of the lower finger an obtuse tubercle indicated. The upper edge of 

 the right hand is crowned with from five to seven large obtuse tubercles, that 

 of the left hand with four to five ; the upper outer sm-face of each hand is very 

 strongly rugose; each movable finger has near the upper base a strong tubercle, 

 which in ve;y old specimens becomes sometimes unequaUy bipartite The fingers 

 1 both hands are very distinctly black coloured, which is of usua occurrence in 

 the whole of this group of aA.c..ii>^. The ambulatory feet equal in length the 

 ^e J; hey are very distinctly laterally compressed, obtusely rounded above and
