(1880) off reefs at Honolulu, Hawaii at 40 
fathoms, and by Brady (1890) at New Cale- 
donia at 3-6 fathoms afid Fiji in the littoral 
zone. 
discussion: Loxoconchella anomala differs 
from the type species, L. honoluliensis, by 
having less complex vestibules and large dorso- 
lateral inflations, especially well developed in 
the wider form. Of lesser importance between 
the two species, L. anomala is deeply reticulate 
whereas L. honoluliensis is punctate to lightly 
reticulate.
