U. minutus and U. candidus of Brown, and possibly also 

 his U. peUucidus (1827) ; but althoui^h these names arc prior

 subsequent authors. In the second edition of Brown's work, 

 published in 1844, he describes " U. hi/alina " of Turton as a 

 different species. It is the Bulla debilis of Gould (1840), and 

 B. subangidata of ^loller (1842).
