This species is quite distinct from all other of the genus 

 to specimens or descriptions of which we have access. It has 

 an even coarser bill than C. magnirostris from the Malay 

 Peninsula and is totally distinct from C. unicolor a form of 

 which occurs together with it. It may possibly be referable 

 to C. ruecki, Oustalet, Bull. Soc. Philom. (7) V. p, 78 (1881), 

 from Kessang, Malacca, which to the best of our knowledge 

 is only known from the types in Paris.
