Remarks.
Bathycadulus queirosi
is noticeably wider than
B. fabrizioi
, the central area is less conspicuous and the apical and oral constrictions are longer. The specimens from
Vanuatu
were found in deeper waters than those from the
Solomon Islands
.
Etymology.
Named for Pedro Fernandes de Queirós (
1563−1615
), Portuguese navigator and explorer, commonly known as Quirós, who discovered, under Spanish flag,
Vanuatu
(
New Hebrides
) and the
Solomon Islands
.
