As Winckworth has shown the generic name Corbida of Roding has nothing in common 

 with Corbnla Lamarck, and since the former must hâve precedence over Lamarck's later name 

 the generic name Corbula^ as hitherto understood, must give way to Aloidis Megerle. The géno- 

 type is Aloidis stilcata (Lam.).

The earlier descriptions of A. monilis by Hinds and Reeve are incomplète, but Smith 

 redescribed the species in détail, while good figures of it v^^ere published by Lynge. Reeve in 

 his remarks on the species apparently mixed up right and left valves, for he stated that "the 

 right valve is sunk in the left valve", whereas it is the globose left valve which is sunk in 

 the rostrate right. 



Distribution: — A. monilis was described from the Philippines, but the species has since 

 been recorded from the Torres Straits, Singapore and the Gulf of Siam. 



In the "Siboga" collection there are a few stray right valves of the species dredged in 

 Madura Bay (St. 51).
