390 ME. J. E. HENDEESON— A CONTEIBUTION 



Genvis Scopimera, De Haau. 



149. Scopimera mycxiroides (Milne-Eclw.). 



Doto myciiroides, Milne-Edwards^ Aim. Sci. Nat. ser. 3, Zool. t. xviii. p. 152, pi. iv. fig. 24 (1852). 



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

 and mud ; Eunore {J. B. H.). 



De Man, on wliat are apparently good grounds, unites Dotilla, Stm. ( = Doto, De Haan, 

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

 Scoinmera is preferable as it is the older name, and Dotilla 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 meral joints of the ambulatory legs.
