ScopiMERA, De Haan. 



Scojjtjnera, De Haan, FauQ. Japon. Crnst., p. 2i (1835) : Milne Edwards, Ann. 

 Sci. Nat., Zool., (3) XVIII. 1852, p. 153. 



Scopimera bas the same deep " cubical " carapace and tbe same 

 general facie.s as Dotilla, but differs in tbe following cbaracters : — 



Tbe carapace is much broader than long and has none of tbe 

 curious sculpture, resembling brain convolutions, that is found, at any 

 rate on the sidewalls, in Dotilla : the external maxillipeds are un- 

 sculptui'ed and their merus, though large, is smaller than their ischium : 

 the abdomen of the m^ile has a, curious wasp-like form owing to the 

 length and narrowness of its fifth segment, which segment may even 

 become elongate-linear by consti-ictiou ; it has no bristles either on the 

 4th tergum or elsewhere : in the female the abdomen consists of 7 

 separate segments. 



Distribution : Indo-Pacific shores, from Karachi to Japan. 



Key to the Indian species of Scopimera. 



I. Chelipeda and legs with a reticulate or subsquaraiform 

 granulation, the chelipeds in the male about twice the 

 length of the carapace : most of the tympana on the 

 legs are ti'aversed by a longitudinal ridge : fifth 

 abdominal tergnm of male long and narrow, but not 



linear S. invottiyatoris. 



II. Chelipeds and legs finely and uniformly granular, the 

 chelipeds in the male neai'er 3 times than twice the 

 length of the carapace : the tympana not subdivided 

 by a ridge : the fifth abdominal tergum of the male is 



long and linear S. cialricaudu. 



According to F. lUiiller, S. ylolosa, De H.ian, is fouiid in Indian waters. The 

 form of the abdomen in this species is similar to that of S. inve^ligafcris, but the 

 carapace is smooth, and the tympana of the legs are different. 



64. Scopimera investigatoris, n. sp. 



Carapace much broader than long, decidedly pentagonal, without 

 distinction of regions, emooth except anteriorly and laterally where 

 there are numerous iiregulaily-scattered grannies : the sidewalls and 

 pterygostomian regions finely granular. 



Orbits broad as in Ocypod'i, shallow, the upper border very oblique, 

 the lower border finely denticulated and very prominent as in Gehisimns. 



External maxillipeds with some obsolescent granulation. Chelipeds 

 and legs finely granular in a somewhat reticulate or subsquamiform 

 way.
