This species is clearly out of place in the genus Turdinus, to which 
Doctor Sharpe has referred it,! but is strictly congeneric with Horizillas 
magna, the type of Horizillas. The present generic name for this 
group is Horizillas Oberholser,? the employment of which in place of 
Malacopteron Eyton * we have elsewhere explained. 
ANUROPSIS MALACCENSIS MALACCENSIS (Hartlaub). 
Brachypteryx malaccensis Harritaus, Rey. Zool., 1844, p. 402 (Malacca, Malay 
Peninsula). 
Three specimens are in the collection, as follows: 
Adult male, No. 171081, U.S.N.M.; Pulo Jimaja, September 21, 
1899. ‘‘Iris dark red; feet pale brownish fleshy.” 
Adult male, No. 176948, U.S.N.M.; Pulo Siantan, September 10, 
1899. 
Adult female, No. 170947, U.S.N.M.; Pulo Siantan, August 24, 
1899. 
They average a very little darker on upper parts, sides, and flanks 
than typical examples of the species from the Malay Peninsula; but 
in the absence of any other characters, these differences appear too 
slight and inconstant to be of subspecific importance. All these 
examples show traces of a nearly completed molt; but the bird taken 
on September 10 (No. 170948, U.S.N.M.) has many more undeveloped 
feathers than the others, particularly on pileum, throat, breast, and 
tail, 
Measurements are given below.
