340 Mr. W. T. Blanford on some Indian 



The species which belong to the genus (Edicerus as thus 

 reduced differ greatly in the structure of the feet. In all, 

 indeed, the first two pairs of legs are furnished with large 

 prehensile hands of a peculiar form ; but in the various species 

 these are different in some parts : in (E. lynceus the lower 

 posterior angle of the fourth joint is not produced into any- 

 process ; in saginatus and affinis this is not half so long as the 

 hand ; in norvegicus it is so long that it meets the tips of the 

 claws, and the hands are much broader than in the others. The 

 same joint in the second pair of hands possesses in saginatus 

 and lynceus a not very long process, and the hands are oval; 

 in ajfinis both the processes and the hands are much elongated 

 and narrow ; and in norvegicus this is the case in a still higher 

 degree, so that they are not much shorter than the preceding 

 joints together, and not much thicker than these. Moreover 

 the lower posterior angle of the hands projects into a finger, 

 and the processes project even further than this. The third 

 and fourth pairs of feet are entirely destitute of claws in nor- 

 vegicus ) in ajjinis the claws are small ; in saginatus long and 

 broad, as long as the fifth joint ; in lynceus, finally, they are 

 more strongly produced and narrower. In the two following 

 pairs the same relations occur ; but here a small claw is seen 

 in norvegicus. The last pair of legs are, as in the other spe- 

 cies, much elongated, and the sixth joint, or claw, is very long 

 and conical. It may also be remarked of this species that the 

 eye-processes are very short and broad, so that the head ap- 

 pears to form a hood over the superior antennas, the flagellum 

 of which is very short. The fourth and fifth joints of the in- 

 ferior antennas are of equal length ; the second joint of the 

 palpus of the maxillipedes is very broad ; the fifth epimera are 

 of the same height as, but much broader than, the fourth.

XLI. — Notes on some Indian and Mascarene Land-Shells. 

 By William T. Blanford, F.G.S., C.M.Z.S.,&c. 



1. On the Lingual Ribbon ofRealia (Omphalotropis). 



The resemblance of the shell and operculum in some forms 

 of Assiminea to those of Realia* is so great that, without an 

 acquaintance with the animal, it is extremely difficult to deter- 



* As no generic distinction has been shown to exist between Realia 

 and Omphalotropis (the only difference being that the latter has a less 

 thickened lip, and a keel round the umbilicus), the two cannot be kept 

 distinct, and the genus must bear the older name of ReaKa.
