P. 926. Scrobicularia longicallus. Off C. Spartel, Marocco,

 sical name Syndosrnya should be retained by some 

 conchologists for species of the established and con- 

 sistent genus Scrobicularia. I have already endea- 

 voured to show that Syndosmya is not founded on a 

 single valid character and that it is long subsequent 

 in point of date to Leach's generic name Abra, as 

 well as to Erycina of Lamarck, which is apparently 

 the same genus.
