from Singapore. Specimen E is from Java, and perhaps belongs 

 to a slightly larger local race ; this example was collected by 

 Dr. Bernstein, by whom it is marked as a female. The sex of 

 specimens C and D has not been i-ecorded by the collectors. 



The plumage of the three specimens C, D, and E agrees with 

 that of A and B, except that the whole of the breast, abdo- 

 men, and thighs in C, D, and E are crossed by transverse bars 

 of dark brown of about an eighth of an inch in diameter, placed 

 at intervals of about a quarter of an inch, the intermediate 

 spaces being white without any tinge of fawn-colour. The 

 transverse bars on the tail are also somewhat more distinct in 

 C, D, and E than in A and B. 



The dimensions of the three specimens C, D, and E are as 

 follows, viz. : — 



I may add that the present species appears to be most nearly 

 allied to Accipiter rhodogaster {Nisus virgatus rhodogaster of 

 Professor SchlegePs * Museum des Pays-Bas'), from which, how- 

 ever, it differs in its shorter tarsi and toes, and in the greater 

 length of its wing as measured from the carpal joint. 



The colouring of the breast is also much paler in A. steven- 

 soni than in A. rhodogaster, taking for comparison what I believe 

 to be the adult males of each species.

 In my ' Monograph of the birds forming the Tanagrine genus 

 Calliste,' which was completed in December 1857, I included 

 descriptions of fifty-two species of this group of birds which 

 were then known to me. During the five years which have
