OEUSTACEA FROM KUTCH AND SIKD. ig 



slightly concave. The Burf«=e is maried with two diagonal depressions, one extend- 

 mg from the base of the fourth endopodite to the oppoA infero-posteita- angle, the 

 other from the inner snb-median projection to near the middle of the lower ed"e 

 but not reaching it, ° ' 



The chel^ appear to be of moderate length, as in most other ca.-c^rtj^^. 

 the upper arm is triangular, smooth, with an obtuse terminal tubercle at the 

 upper outer ridge, and a much sharper tubercle at the upper inner one. The palm 

 of the right hand (the only one as yet found preserved) is a Uttle longer than hi-h 

 rounded above and below, and almost equally convex on the outer and inner sid°es! 

 The surface was probably smooth, or nearly so; it is partially decomposed or 

 removed in the specimen and appears, therefore, reticularly scrobiculate. The 

 fingers are very strong,, equal in length to the height of the hand; the immovable 

 stronger, a little shorter, but more convex at the outer margin than the other ; 

 the inner edges are irregularly dentate and sulcated longitudinaUy from within. 

 None of the ambulatory legs are preserved. 



The greatest width of the sternum is slightly less than haK that of the carapace ; 

 the third sternite is rather coarsely scrobiculate, with a slightly convex posterior 

 edge, emarginate and strongly depressed in the middle. Tail long and of 

 moderate width; all the joints apparently separated:* the first very shorf, but 

 apparently broadest, the next at least double as long, and the following gradually 

 increasing in length, but decreasing in breadth, each with somewhat concave lateral 

 margins; the last is elongately semioval, anteriorly with projecting edges, and 

 posteriorly obtusely rounded. 



So far the description of the Indian species which Al. Milne-Edwards has, I 

 believe correctly, referred to his new genus Galenopsis, though in the descrip- 

 tion of the species (loc. cit., p. 350,) he suggests that a new generic name may 

 be required for it. On this account only have I gone into several minor details 

 which would otherwise be thought unnecessary, but there are several points in 

 the characteristics of the genus which yet require correct definition. 



The affinities of Galenopsis to Galena are expressed in the general shape 

 of the carapace, much more inflated anteriorly than posteriorly, the subhepatic 

 and pleural regions being considerably tumid ; in the short antero-lateral, and 

 in the much longer and concave postero-lateral, margins ; in the moderate size of the 

 orbits directed towards the front and provided with a large internal hiatus, the basilar 

 ioint of the antennge being very small; further, in the subquadrangular shape of 

 the third endopodite of the outer maxiUipeds, the large size of internally tuber- 

 culated fingers on the hands, and the apparently entirely separated joints of the 



tail in the male sex, .,..,.,. ^. - .• r 



The cHef difference from Galena consists in the indistinct separation of 



the lobes of the carapace, and,-if we are allowed to regard the present species as 



a true Galenopsis -m the peculiar depression of the outer maxilUpeds, the second 



*0n the specimen the third, fourth, and fifth joints are mostly seen as impassions only, and they are separated 

 aWtthrou^hrhyfine raised lines which appear to indicate sutures hetween the ^omts, or at least considerably 

 excavated grooves. .
