SuTER is wrong in suggesting that O. F. Mûller ^) designated Anomia craniolaris as 

 the génotype of Anomia in 1776, for in tlie work cited there is no mention of any of the 

 species having been selected as the type. The first type désignation was made by Children in 

 1823, who selected Anomia ephippitim Linnaeus as the génotype. Woodring has published a 

 good description of the genus Anoinia.

The species of this genus are in a state of great confusion, but there can be no doubt 

 that several of the so-called species of Gray and Reeve are based on individual variations of 

 the shells. Unfortunately the material at my disposai is not sufficient for a revision of the Indo- 

 Pacific species, but from an examination of the types of the various species in the British Muséum 

 (Nat. Hist.), London, I hâve little doubt that A. plenihinium Reeve (op. cit., pi. i, fig. 2), A. sol 

 Reeve (pi. i, fig, 4), A. malleata Reeve (pi. VI, fig. 25) and A. ar^yritis Reeve (pi. VI, fig. 31) 

 are ail synonyms of this variable species.
