Genus LACUSTROICA. 
Lacustroica North, Victorian Naturalist, 
Vol. XXVI., p. 138, Jan. 13th, 1910. Type 
(by monotypy) .. .. .. .. Lacustroica whitei North. 
North’s diagnosis reads : “ Exposed portion of bill slightly less than half 
the length of head, moderately straight, equal in height to breadth at nostril, 
the culmen distinctly arched, and decurved towards the tip ; tongue grooved 
above, bifid at the tip. First primary short, the second equal in length to 
the seventh, the almost square end of the wing formed by the third, fourth, 
fifth, and sixth primaries, which are almost equal in length. Tail about two- 
thirds of the length of the wing. Tarsi long, slender, about twice the length 
of the bill.” 
North added : “ Remarks. The genus Lacustroica is allied to Entomophila, 
and to that section of it winch includes E. picta, but differs from it principally 
in having a shorter bill, longer tarsi, and a different wing formula.”
