Other authors, including Serene (1962) and Ingle (1963), re-illus- 

 trated parts of one or more of the above specimens. A comparison 

 of these illustrations revealed several discrepancies, some of which are 

 cited below. 



Gravier (1937) figured a small specimen from the Poulo Condore 

 Islands in which the third lateral carinae of the telson were subdivided 

 into three erect spines; Serene (1962) refigured Gravier's specimen 

 and showed an uninterrupted carina terminating in a single spine. 

 Gravier's specimen has a rounded lobe between the spines of the 

 basal prolongation of the uropod; the lobe is lacking in the Chinese 

 specimen of M. 'pilaensis figured by Schmitt (1929) and Ingle (1963). 

 These are among the discrepancies noted in the literature. 



All but the two specimens of M. pilaensis from Elphinstone Island 

 have been examined for this study. M. pilaensis is redescribed, a 

 new species from the Poulo Condore Islands, M. serenei, is described, 

 and the single, mutilated specimen from the Gulf of Aden, which 

 probably represents a new species, is briefly characterized but 

 not named. 



The descriptions given herein do not include generic characters, 

 which are summarized separately in the generic definition. Syn- 

 onymies include all references in the literature. Measurements of 

 total length (TL) are made along the midline, from the apex of the 

 rostral plate to the bases of the movable submedian teeth of the 

 telson. Telson length is also measured to the bases of the submedian 

 teeth. Carapace length (CL) is measured along the midline and 

 does not include the rostral plate. In general, appendage setation 

 is not shown in the illustrations; on most of the specimens the setae 

 are badly damaged. 



I would like to thank R. W. Ingle of the British Museum (Natural 

 History) (BMNH) and J. Forest of the Museum National d'Histoire 

 NatureUe, Paris (MNHNP), for makmg available on loan specimens
