 times as large as eepals, quite scssile. Lip very large ; its laieral lobes oblong, iwo- 

 lobed, small ; tlie miildle one very broad, unguiculate, reniform, or raiher crescent- 

 shaped. Cresl small with five collateral equal downy round tubercles , in front of 

 which is a itiin three-lobed arched membrane. Column-wings very large, hatchet- 

 shaped , wiih the angles rounded. This is one of the finest of the genus. It differs
