""Char. gen. — Most nearly related to Siphonorhis; Scl. (monotypic; type S. 

 americana,) but nasal tubes shorter, 1.5 mm. in height (in skin) as compared with 3 

 mm. in Siphonorhis; bill disproportionaUy smaller, its outline from above more regu- 

 larly triangular, less shield-shaped, the upper mandible not convex in outline, the 

 ridge on its cutting edge less developed; rictal bristles apparently actually stronger; 

 tail squarer, less graduate; tarsus and toes disproportionately longer." (Chap- 

 man, 1. c). 



^ Microsiphonorhis brewsteri Chapman: " In general coloration resembling Sipho- 

 norhis americana, but paler throughout, throat and pectoral band white sharply 

 defined from the black subterminal area, which is much broader; abdominal region 

 buflfy white instead of ochraceous buff, more narrowly and less regularly barred; 

 tertials narrwoly tipped with white." (Chapman, I.e.). Size smaller; female: 

 wing, 1 19.5; tail, 94.4; bill, 8.5 mm. Detailed description given. The type, an 

 adult female is the only known specimen.
