OR Family of Crowned Humming Birds. 



Body moderate, sometimes very minute as in the genus 

 Mlorochera. Bill short slender and straight, serrated at tips 

 in tlie genus Chrysolampis. Feathers projecting on the culmen, 

 especially so in the genera Bellona and Chrysola'inpis, in

 whole body. Wings long, nearly reaching the end of tail. Tail 

 rounded, excepting in the genus Loddigesia. Sexes unlike.
