Genus — M ACLENNANIA. 
Maclennania Mathews, Austral Av. Rec., 
Vol. III., pt. 5, p. 127, December 28, 
1917. Type (by original designation) Cincloramphus maihewsi Iredale. 
I introduced this genus name in honour of William Rae Maclennan, who 
was instrumental on account of Dr. W. Macgillivray in the discovery of the 
North Queensland Claudie River novelties. The genus had been recognised 
by most workers and as the genus name Ptenoedus Cabanis had been used. 
It was shown that that name, however, had been proposed simply as a substitute 
of more classical formation for Cinclorhamphus Gould, that being a hybrid of 
Latin and Greek roots. The eccentricities of would-be purists is well seen in 
their action in connection with another compound, Colluricincla, which became 
Collyriocichla , while Cinclorhamphus and Cinclosoma were left unchanged, 
but these each showed as palpable an erroneous formation. As this genus has 
been confused with the preceding, the distinguishing features may be noted, 
though the differences are so marked they should never have been put together 
by ornithologists separating the other Gouldian genera. As instance, 
Maclennania shows a short first primary, whereas Cinclorhamphus has the first 
primary so minute that it is hidden by coverts, and the second primary 
appears to be the longest. 
The genus is composed of smaller birds with shorter bills, more rounded 
wings, rounded long tail and shorter stout legs and feet. The sexes are a little 
dissimilar in size. 
The bill is shorter than the head, similar to that of the preceding but 
correspondingly deeper. 
The wing formula is very different , the first primary short, a little less 
than half the length of the second, which is subequal to the third, fourth and 
fifth and longest, the rest successively a little shorter until the ninth, which 
is equalled by the secondaries, while the tertials are elongate and nearly equal 
the primaries in length but are broader feathers. 
The tail is long and rounded, the feathers with pointed tips, but the outer 
webs not notably reduced in size. 
The legs are shorter and stout, but not so strong as in the preceding genus, 
the tarsus showing five scutes anteriorly, and posteriorly bilaminate ; the 
toes weak and slender.
