membrane, and the apical part corneous and vaulted, with the tip hooked and acute ; the tip of the 
lower mandible overlapped by that of the upper mandible, and the gonys short and curved upwards ; the 
Nostrils placed in the fore part of the membranous portion of the bill, and near the lateral margin, with

DiDus Linn.-f 
Bill strong, and much longer than the head ; with the culmen straight for some distance from the 
forehead, and then gradually arched to the tip, which overlaps that of the lower mandible, and is acute ; 
the sides compressed ; the lower mandible strong, with the gonys short, and suddenly curved upwards ; 
the nostrils placed in the membranous portion (which occupies two thirds of the bill), near the apex and 
the lateral margin, with the opening oblique, exposed, and oval. Wings imperfect. Tail apparently 
consisting of a tuft of (five) curved broad feathers. Tarsi as long as the middle toe, robust, and covered 
with rather small irregular scales, lessening towards the knee joint, and a few at the base of the toes 
narrow and transverse. Toes moderate, broad, and transversely scaled above ; the outer toe shorter than 
the inner, and the base of the anterior toes free ; the hind toe rather long, on the same plane with the 
others, and covered above with transverse scales ; the claws short, strong, and blunt. 
This bird formerly inhabited the Island of Mauritius, where it is supposed by Mr. Strickland to have lived in the 
dense forests of palms and various other trees that once covered the island, " wandering from tree to tree, tearing with 
its powerful beak the fruits which strewed the ground, and digesting their stony kernels with its powerful gizzard, 
enjoying tranquillity and abundance until the arrival of man destroyed the balance of animal life and put a term to its 
existence." The nest is stated by the old voyagers to have been made of herbs or grass heaped together in the depth of 
the forest, and the female is said to have laid only a single egg at a time.

* I had formerly considered that this subfamily formed part of the order Struthionid^, but M. Reinhardt's idea of the type being 
a pigeon having been so ably proved by the careful investigation bestowed on the head and foot by H. E. Strickland, Esq., and Dr. Melville, 
I am now induced to place this remarkable subfamily among the Colvmb^. 
I Established by Linnseus in 1766. Raphus of Moehring (1752) is synonymous.
