390 ME. J. E. HENDEESON— A CONTEIBUTION 



Genus Scopimera, De Haan. 



149. Scopimera myctikoides (Milne-Eclw.). 



Doto myctiroides, Milne-Edwards, Ann. Sci. Nat. ser. 3, Zool. t. xviii. p. 153, pi. iv. fig. 24 (1852) . 



Rameswaram and Tuticorin ( Thurston). Common at Eameswarani, burrowing in sand 

 and mud; Ennore {J. R. H.). 



De Man, on what are apparently good grounds, unites Botilla, Stm. ( = Doto, De Haan, 

 nom. praiocc), and Scopimera, De Haan, selecting the former name for the genus ; but 

 Scopimera is preferable as it is the older name, and Botilla has more recently been 

 used to designate a genus of Mollusca. 



In a very large series of this species I have as yet only met with males. There is still 

 much to be learned about the genus, especially as to the nature of the curious ' tympana ' 

 on the sterna and on the moral joints of the ambulatory legs. 



Distribution. Malabar (Milue-Bdivards) ; Strait of Gaspar (Stimpson) ; Java {Brit. 

 Mus.) ; Singapore ( Walker) ; Seychelles {liters).
