This species has been long known in a fossil state only, until A. 

 Milne-Edwards in 1865 supposed that it might also be found living in 

 the Indian Ocean; his surmise was corroborated by the discovery of living 

 specimens at New Caledonia (1873). Afterwards Ortmann established the 

 identity of M. serratus with M. latreillei. 



The various names attributed to this species are due not only to the 

 different designation of geologists and zoologists (who first called this 

 species M. serratus) but also to the variability this species evidently 

 displays in the succeeding stages of age. Indeed, if we compare Stimpson's 

 figure of a young specimen of M. serratus and its cheliped (1907) with
